Course Overview

Soybean rode the poultry boom from curiosity to contract crop across Africa's maize belts: 40% protein, 20% oil, feed mills hungry for tonnage, and free nitrogen left behind for the maize that follows. It is also a crop of specific, learnable tricks — and this course teaches them in order of return. First, inoculation: the few-dollar sachet of specialist rhizobium that most African soils lack, worth 30–50%+ on new land, taught as a ten-minute technique with a pink-nodule test to prove it worked. Then the population stand this crop demands, phosphorus as the purchased key, the daylength rule behind released-variety discipline, the rust scouting habit, and the quality war against splits, greens and moulds. Harvest is a race the course names honestly — the shattering clock — and storage splits into grain stock and the fragile, premium-earning seed stock. The business module sells into contracts, traders, the town food trade (with the absolute cooked-soy heat rule) and your own livestock rations, and writes the final plan for the maize–soybean pair, because the system margin beats either crop alone.

What You Will Learn

Month 1: The Protein Crop, the Rhizobium Trap & the Markets

Start

Lesson 1.1 — The protein crop the feed mills are hunting

Soybean is the world's protein workhorse — ~40% protein and 20% oil in one seed — and Africa's fastest-growing field-crop market. The engine is the poultry boom: every broiler and layer ration is built on soybean meal, and most African feed mills import it at painful prices. Add oil pressing, human foods (soy milk, flour, textured 'chunks'), and the crop's nitrogen-fixing gift to the following maize, and soybean has moved from curiosity to contract crop across the continent's maize belts in a decade.

Season: 90–130 days by variety; a rains-season row crop for the same land and equipment as maize.
Yields: African smallholder average ~1 t/ha; good management with inoculated improved seed reaches 2–3.5 t/ha.
Rotation gold: a well-nodulated crop can leave the equivalent of a meaningful nitrogen dressing for next season's maize, plus a clean disease break.

Lesson 1.2 — The one lesson that towers over the rest

Soybean fixes nitrogen ONLY when its roots carry nodules of the right rhizobium bacteria — and here is the trap: the soybean rhizobium is a specialist that most African soils do not naturally contain (unlike cowpea's and groundnut's easy-going partners). An uninoculated soybean crop on new land sits pale, hungry and stunted while its owner blames the seed. The fixes, in order of importance:

Inoculate the seed with soybean-specific rhizobium inoculant at planting — a sachet costing a few dollars that routinely adds 30–50%+ yield on first-time land (Module 2 teaches the technique).
Or plant 'promiscuous' varieties — African-bred lines (many from IITA) that nodulate with native rhizobia; lower ceiling than inoculated specialist varieties, but forgiving where inoculant is unreachable.
Once soybean has grown inoculated on a field for some seasons, the bacteria persist and the response fades — but on NEW land, inoculation is the single highest-return act in this course.

Lesson 1.3 — Markets at a glance

Buyer	Wants	Notes
Feed mills / soybean-meal processors	Tonnage, clean dry grain, low splits	The anchor market; many run outgrower/contract schemes
Oil crushers	Volume; oil + meal both sold on	Often the same industrial buyers
Human-food processors & households	Clean white-hilum types for milk/flour where preferred	Growing town trade: soy milk, flour blends, chunks
Seed companies & neighbours	Certified-quality seed grown carefully	Soybean seed is fragile and always scarce — a premium niche (Module 2)

Practical Assignment — Month 1: Map your soybean market: find the nearest feed mill, processor or outgrower scheme and record its buying terms and specs (or the trader prices where no scheme operates); price soybean products in town (meal, oil, soy flour/milk if sold). Ask your agro-dealer and extension office about soybean-specific inoculant availability and about released varieties (noting promiscuous types and maturity days). Write one paragraph: your target channel and variety.

Month 1 Quiz — 10 Questions

Answer every question. Aim for at least 7/10 before marking this month complete. Each answer comes with an explanation — read them even when you are right.

1. Soybean seed contains roughly:

Why: The densest protein package in field cropping — the reason every poultry ration and feed mill hunts it, and the anchor of its market boom.

2. The engine of African soybean demand is:

Why: Feed mills import meal at painful prices; local grain substitutes directly. The Poultry courses' industry is this course's customer.

3. Soybean's rhizobium partner is:

Why: The central trap of the crop: no native partner means no nodules, no fixed nitrogen, and a pale stunted field. The inoculant sachet exists precisely for this.

4. On first-time soybean land, inoculation typically adds:

Why: The highest-return single act in the course: living bacteria applied to seed unlock the nitrogen factory the plant was bred around.

5. 'Promiscuous' varieties are:

Why: IITA's answer to the inoculant-access problem: a lower ceiling than inoculated specialists, but nodules and nitrogen where the sachet cannot reach.

6. A well-nodulated soybean crop leaves the next maize:

Why: Rotation gold: the legume contract pays the cereal that follows — the farm-system argument that completes soybean's business case.

7. Good managed African soybean yields reach:

Why: Inoculated improved seed, full stands and timely harvest close the gap — the same levers as everywhere in this college, with the sachet added.

8. The anchor buyers of soybean tonnage are:

Why: Industrial demand gives soybean something few smallholder crops enjoy: standing contract channels with published specs and collection points.

9. White-hilum soybean types matter to:

Why: The food trade pays attention to the seed's eye-spot colour; knowing your buyer decides whether that column matters at variety choice.

10. Once soybean has grown inoculated on a field for seasons:

Why: Inoculation is establishment technology: the first crops build the soil's population. Budget the sachet for every NEW field and relax on veterans.

Month 2: Seed, Inoculation & the Population Stand

Locked

Lesson 2.1 — Seed: fragile, short-lived, handled like eggs

Soybean seed is the most delicate in this college: a thin coat over a living embryo that cracks when dropped, dies young in storage (viability falls sharply after ~8–12 months in ordinary stores), and drinks moisture from humid air. Rules: source fresh certified/QDS seed each season or save your own with real care (dry, cool, hermetic, never dropped in sacks); always germination-test (50 seeds, damp cloth, 5 days — below 70–75%, raise the rate or reject the lot); never plant last year's leftover bag on hope.

Lesson 2.2 — Inoculation technique: ten minutes that grow the crop

Buy soybean-specific inoculant (check the expiry date and that it was kept cool — living bacteria die in a hot shop window).
In shade, on planting day: moisten seed lightly with water (a sugar or gum-arabic solution sticks better), sprinkle the inoculant powder, mix gently until every seed is dusted grey-black.
Plant within hours, into moist soil — sun and heat kill the bacteria on the seed; never leave inoculated seed baking in an open pan.
Check success at 4–6 weeks: dig (don't pull) a few plants — pink-red insides in root nodules = working nitrogen factories; white/green nodules or none = the field will need rescue nitrogen and next season a fresh, better-kept inoculant.

Lesson 2.3 — Planting for the combine you don't own yet

Element	Standard	Why
Sowing time	Main rains established; warm soil	Cold wet seedbeds rot the fragile seed
Spacing	Rows 45–60 cm, seeds 5 cm apart in-row, 3–4 cm deep	~300,000–400,000 plants/ha — soybean yields on POPULATION; dense stands also set pods higher off the ground (easier harvest, less loss)
Seed rate	60–100 kg/ha adjusted by germination test	A real budget line — the price of a population crop
Fertility	No (or minimal starter) N — the nodules' job; P is the purchased key (SSP/compound at planting); K where soils test low; lime sour soils	P powers nodulation and pod fill; acid soils cripple rhizobia

The two-sachet insurance: on new land, serious growers double-inoculate (two sachets' rate) — the cost is small, the downside of failed nodulation is the whole crop's nitrogen. And where phosphorus is skipped, inoculation underperforms: P + inoculant is a package, not a menu.

📺 Watch it done: The ten-minute inoculation — and planting for 350,000 plants. Open curated video search → The written lesson above is complete on its own — the video is optional reinforcement.

Practical Assignment — Month 2: Source fresh seed and run the 50-seed germination test, recording the result and your seed-rate adjustment. Obtain inoculant (check expiry and storage conditions at purchase); inoculate in shade on planting day and sow at least four 10-metre rows at 45–60 × 5 cm, 3–4 cm deep, with P fertiliser, within hours. Record everything: product, lot, timing, weather. At three weeks, count your stand; at 4–6 weeks, dig five plants and score nodules (pink/white/none) — your proof sheet.

Month 2 Quiz — 10 Questions

Answer every question. Aim for at least 7/10 before marking this month complete. Each answer comes with an explanation — read them even when you are right.

1. Soybean seed viability in ordinary storage:

Why: The fragile embryo dies quietly in the sack. Fresh seed plus a germination test every season is the only safe rule for a population crop.

2. The germination-test threshold for action is:

Why: Fifty seeds and a damp cloth prevent the classic soybean disaster: a half stand discovered when the rains are already spent.

3. Inoculated seed must be:

Why: You are planting living microbes. Shade, speed and moist soil deliver them alive to the roots they must colonise.

4. Working nodules at 4–6 weeks show:

Why: Leghaemoglobin's pink is the crop's health certificate. Dig, don't pull (pulling strips nodules off), and read the colour: pink means the sachet worked.

5. White or absent nodules mean:

Why: The 4–6 week check exists so failure is caught while rescue nitrogen can still save the season — and the diagnosis (dead inoculant? sour soil? no P?) fixes next year.

6. Soybean population targets are:

Why: Soybean yields on numbers, and dense stands set pods higher — less ground loss at harvest. Population is architecture and economics at once.

7. Soybean's purchased nutrient key is:

Why: P powers the nodulation the inoculant enables; skipping P starves the very bacteria you paid to apply. N stays minimal — that's the nodules' job.

8. Acid (sour) soils affect soybean by:

Why: The nitrogen partnership is pH-sensitive: lime is not cosmetic on sour land, it is the inoculant's life support.

9. The two-sachet insurance on new land means:

Why: First-time fields are where nodulation fails and where it pays most; doubling the living dose is cheap certainty.

10. Soybean seed rate is:

Why: A population crop costs population seed. Budget it honestly and protect it with the test — thin soybean never recovers.

Month 3: Weeds, Water, Stages & the Rotation Seat

Locked

Lesson 3.1 — Weeds: win the first six weeks

Soybean seedlings are slow and low; weeds in the first 4–6 weeks cost more yield than any other management failure after stand and nodulation. Programme: clean seedbed at planting; first weeding at 2–3 weeks, second at 5–6 weeks; after canopy closure (helped by your dense stand) the crop shades the rest out. Hoe shallow — soybean roots and nodules ride near the surface. Where herbicides are used locally, follow label and extension guidance exactly; the hand-hoe programme above delivers the same result with timeliness.

Lesson 3.2 — Water and the flowering clock

Critical windows: establishment, and flowering through pod fill (~weeks 6–12) — stress there aborts flowers and shrinks seed. Mid-vegetative dry spells are tolerated far better.
Waterlogging suffocates nodules within days — drainage or ridging on heavy land.
Soybean is daylength-sensitive: varieties are bred for latitude bands, and a variety moved far north/south flowers at the wrong size. Plant RELEASED-for-your-area varieties and respect recommended planting windows — the calendar is part of the genetics.

Lesson 3.3 — Reading the crop

Stage	See	Do
V-stages (leaf growth)	Trifoliate leaves unfolding	Weedings; nodule check at 4–6 weeks
R1–R2 (flowering)	Small white/purple flowers at nodes	Water status watch begins; no stress, no deep cultivation
R3–R6 (podding & fill)	Pods lengthen, seeds swell	The yield window — scout pod pests (Module 4)
R7–R8 (maturity)	Leaves yellow and DROP; pods brown; seeds rattle	Harvest fast — Module 5's shattering clock starts

Lesson 3.4 — The rotation seat

Soybean's classic seat is between maize crops: it returns nitrogen, breaks cereal pest cycles, and its early canopy fits the machinery and labour calendar maize built. Never soybean after soybean repeatedly (rust, nematodes and soil diseases build); groundnut and beans share some diseases — space legumes apart in the cycle. The maize–soybean pair is the backbone of every serious feed-grain area on the continent for a reason: each crop sells to the same feed mill, and each makes the other cheaper to grow.

📺 Watch it done: Two weedings and a closed canopy — reading V and R stages on real plants. Open curated video search → The written lesson above is complete on its own — the video is optional reinforcement.

Practical Assignment — Month 3: Complete both shallow weedings on schedule (2–3 and 5–6 weeks), recording dates and hours. Track and date your crop's stages: first trifoliate, R1 flowering, R3 podding, R7 leaf drop. Keep a water log through weeks 6–12 (rain days, any stress signs, any waterlogging). Draw your four-season rotation map placing soybean between maize crops and spacing it from other legumes, with one sentence of reasoning per season.

Month 3 Quiz — 10 Questions

Answer every question. Aim for at least 7/10 before marking this month complete. Each answer comes with an explanation — read them even when you are right.

1. Soybean's costliest management failure after stand and nodulation is:

Why: Slow low seedlings lose the early race badly. Two timely shallow weedings plus a dense closing canopy is the whole cure.

2. Hoeing near soybean rows must be:

Why: Every nodule cut is nitrogen lost. The groundnut lesson echoes: surface-feeding legumes are weeded with a light hand.

3. The critical water window is:

Why: Stress at flowering aborts pods silently; the same weeks decide seed size. Vegetative dry spells are survivable — R-stage stress is not.

4. Waterlogging on soybean:

Why: The nitrogen factory breathes. Even short flooding turns a pink-nodule crop pale — drainage is nodule protection.

5. Soybean's daylength sensitivity means:

Why: A variety moved far from its band flowers tiny or too late: the calendar is inside the genetics. The released list is not bureaucracy, it is physics.

6. At R7–R8 maturity, soybean:

Why: The self-defoliating finish is the harvest signal — and Module 5's warning: from rattle onward, delay pays the ground, not the grower.

7. Soybean's classic rotation seat is:

Why: The maize–soybean pair is the feed-grain backbone: each makes the other cheaper and both sell to the same mill. Repetition of soybean itself builds rust and nematodes.

8. Legumes in the rotation cycle should be:

Why: A legume slot is not interchangeable: shared pathogens ride between legume species. The cycle plans the family, not just the crop.

9. The nodule check belongs at:

Why: Early enough to rescue with N if the sachet failed, late enough for nodules to show their pink — the crop's mid-term exam.

10. Deep cultivation during flowering:

Why: By R1 the field work is done: the crop wants water, scouting and peace through its deciding weeks.

Month 4: Rust, Pod Pests & the Quality Enemies

Locked

Lesson 4.1 — Soybean rust: the airborne threat

Asian soybean rust is the crop's most explosive disease in Africa: tiny tan-brown pustules on lower-leaf undersides that, in warm wet spells, climb the plant and defoliate a field in 2–3 weeks during pod fill — the exact moment yield is being assembled. Management:

Scout from flowering onward: hand lens or sharp eyes on LOWER leaf undersides, weekly in humid weather.
Tolerant/resistant released varieties where available; early-maturing varieties often escape the worst late-season pressure.
Fungicide response where the crop justifies it: a triazole-type spray at first pustules (or preventively at R1–R3 in known rust areas), repeated per label — timing beats product; a spray after defoliation is money thrown at history.
Destroy volunteer soybean between seasons — rust's green bridge.

Lesson 4.2 — The rest of the gallery

Problem	Recognise	Act
Pod-sucking bugs (stink/shield bugs)	Shrivelled, dimpled, stained seed; flat pods	Scout at podding; treat real infestations (evening, threshold-based); field edges first
Pod borers & leaf caterpillars	Holed pods; windowed leaves	Healthy crops tolerate much defoliation pre-flowering; protect the R3–R6 window
Bacterial blight / wildfire	Angular water-soaked leaf spots	Clean seed, rotation; rarely economic alone
Frogeye leaf spot & others	Round grey-brown leaf spots	Resistant varieties, rotation, residue management
Nematodes	Patchy stunting, galled or stubby roots	Rotation with cereals; resistant varieties where identified
Hares, rodents & birds at emergence	Grazed seedling rows	Field presence in week one; gap-fill fast

Lesson 4.3 — The quality enemies: splits, greens and moulds

Feed mills and food processors buy QUALITY, and soybean's quality is made at the margins of harvest. Three graders' enemies: splits (cracked seed from rough threshing and over-dry handling), green seed (harvested immature or drought-forced), and moulds/heating (stored damp — with the same mycotoxin stakes as every crop in this college). Module 5's timing and gentleness rules are written against exactly these three.

📺 Watch it done: Pustules on the underside — the rust scout's routine and the splits-greens-moulds triangle. Open curated video search → The written lesson above is complete on its own — the video is optional reinforcement.

Practical Assignment — Month 4: From flowering onward, scout weekly: check lower-leaf undersides of ten plants across the plot for rust pustules, and beat five plants over a tray at podding to count pod bugs; record all findings. Price a triazole fungicide option locally and write your spray trigger (first pustules / preventive R1–R3 if your area is known rust country) without necessarily buying. Write your three-enemy quality plan: how you will prevent splits, greens and moulds at harvest and after.

Month 4 Quiz — 10 Questions

Answer every question. Aim for at least 7/10 before marking this month complete. Each answer comes with an explanation — read them even when you are right.

1. Asian soybean rust can defoliate a field:

Why: The most explosive disease on the crop strikes exactly when yield is being assembled — which is why scouting starts at flowering, not at symptoms' convenience.

2. Rust scouting looks at:

Why: Rust climbs from the bottom. The underside habit finds it at the few-pustule stage when a spray still changes the outcome.

3. A rust fungicide applied after defoliation is:

Why: Fungicides protect leaves that exist. First-pustule (or preventive R1–R3 in known areas) timing is the entire skill.

4. Early-maturing varieties relate to rust by:

Why: A crop that finishes before the epidemic peaks was never in the room — earliness as disease escape, the pearl-millet drought logic transferred.

5. Volunteer soybean between seasons:

Why: The pathogen needs living tissue year-round; volunteers provide it. The rotation gap only works when the bridge is down — sunflower's sclerotinia lesson repeated.

6. Stink bug damage shows as:

Why: Pod-suckers inject and drain developing seed — invisible on the outside, graded down at the mill. Podding-window scouting with evening threshold sprays protects the R3–R6 yield.

7. Pre-flowering leaf feeding by caterpillars:

Why: Soybean compensates for early defoliation; it cannot compensate for lost pods. Thresholds and timing put chemistry only where it pays.

8. The three graders' enemies of soybean quality are:

Why: Rough threshing, mistimed harvest and damp storage — every one made or prevented in the farmer's own hands at the season's margins.

9. Mouldy or heated soybean carries:

Why: The universal law crosses into the protein crop: moisture discipline protects the feed chain, the food chain and the price alike.

10. Nematode problems in soybean are managed by:

Why: The maize–soybean alternation earns again: cereal seasons starve the legume's nematodes while the legume feeds the cereal's nitrogen.

Month 5: The Shattering Clock, Threshing & Two Stocks

Locked

Lesson 5.1 — The shattering clock

Soybean announces harvest honestly — leaves drop, pods brown, seeds rattle at ~13–15% moisture — and then punishes delay like no other crop here: dry pods shatter, twisting open in afternoon heat and firing seed onto the ground. Field losses of 10–30% from late harvest are common and invisible until you look down. Rules:

Harvest within days of rattle stage — not weeks. Morning work (pods slightly damp, less shatter) for hand harvest.
Hand method: pull or cut plants, stack small heaps/bundles on tarpaulins, move to the threshing floor same day where possible.
Where small combines or hired threshers operate, book them AGAINST the rattle date, not after it.
Shattering-tolerant released varieties exist — one more column worth reading at seed choice.

Lesson 5.2 — Threshing gently, drying honestly

Thresh on tarpaulins: beat bundles LIGHTLY with flexible sticks, or rub through by trampling boards — soybean splits under enthusiasm, and splits are the number-one grade cut. Motorised threshers: correct drum speed per the operator's soybean setting.
Winnow clean; remove greens, stones and pods.
Dry to 11–12% for sale, 10–11% for storage — thin layers on tarpaulins/racks, never bare soil, turned gently. The bite test: cracks cleanly, no dent. Over-dried seed (sun-baked days at 8%) splits at every later touch — dry enough, then STOP.

Lesson 5.3 — Storage and the two stocks

Grain stock (sale): clean sacks on pallets, dry ventilated store, monthly checks; soybean stores well at correct moisture but heats fast if damp — a warm sack is an alarm.
Seed stock (next season + the premium niche): the fragile-seed rules concentrated — hand-harvested from your best area, gently threshed, dried to ~10–11%, hermetic containers, cool and shaded, never dropped; germination-tested before the season. Because everyone's soybean seed dies young, the careful grower's tested fresh seed sells at a strong premium every planting time — the potato/yam seed business logic in its lightest form.

Lesson 5.4 — Home and town processing

Beyond the mill gate, soybean's food uses are a real cottage industry: soy milk (soak, grind, boil WELL, strain), soy flour for porridge blends (roast before milling — raw soybean contains anti-nutrition factors that heat destroys; never feed raw beans or raw flour to people, poultry or pigs), tofu from milk plus a coagulant, and roasted snack beans. The heat rule is absolute and is the food-safety centrepiece of this module: properly cooked/roasted soy is excellent food; raw soy is not.

📺 Watch it done: Rattle date to threshing floor — gentle sticks, target moisture, and the seed-stock rules. Open curated video search → The written lesson above is complete on its own — the video is optional reinforcement.

Practical Assignment — Month 5: Record your rattle date and harvest within days of it (morning work), noting the gap — then estimate ground loss honestly by counting shattered seed in three 1 m² quadrats. Thresh gently on tarpaulins, winnow, and dry to the crack-clean-no-dent standard, recording days and final estimate. Separate a seed stock from your best area into a hermetic container (cool, shaded, labelled) and set a pre-season germination-test reminder. Store grain stock in sacks on a pallet with a monthly check log.

Month 5 Quiz — 10 Questions

Answer every question. Aim for at least 7/10 before marking this month complete. Each answer comes with an explanation — read them even when you are right.

1. Soybean punishes late harvest by:

Why: The shattering clock starts at rattle stage. Days matter; weeks are a levy paid to the ground — harvest is booked against the rattle date.

2. Hand harvest is best done:

Why: A little dew is the hand-harvester's friend: the same pods that explode at 2 pm open gently at 8 am.

3. The number-one grade cut at soybean buying points is:

Why: Gentle flexible-stick threshing on tarpaulins, correct drum speeds, and the dry-enough-then-STOP rule exist because every crack is discounted money.

4. Target moistures are:

Why: The oil-and-protein seed sits between grain and oilseed laws: dry enough to keep, not so baked it splits at every touch thereafter.

5. A warm soybean sack in the store is:

Why: Heating is spoilage announcing itself. Monthly checks by hand catch it while re-drying still saves the stock.

6. The soybean seed-stock rules are:

Why: Fragility concentrated: seed is the one lot where every rule doubles. Its reward is the standing premium fresh tested seed earns each planting season.

7. Tested fresh soybean seed at planting time:

Why: The lightest version of the seed-business logic running through this college: care plus a germination certificate converts fragility into margin.

8. Raw soybean fed to people, poultry or pigs:

Why: The heat rule is absolute: roast or boil well before any food or feed use. Cooked soy is excellent; raw soy undoes the very protein it carries.

9. Soy milk production requires:

Why: The boil is not optional flavour — it is the heat treatment that makes soy food safe and digestible. Every cottage product in this module passes through proper heat.

10. Drying soybean happens on:

Why: The universal off-ground law, with a gentleness clause added for the crop that splits: thin layers, soft handling, and stop at target moisture.

Month 6: Contracts, Rations & the Maize–Soybean Plan

Locked

Lesson 6.1 — Selling into an industrial market

Channel	How it works	Your move
Feed mill / processor contracts & outgrower schemes	Registered farmers/groups, published prices or formulas, specs (moisture, splits, foreign matter), collection points	The anchor: register early, read the spec before planting, deliver on grade — contract soybean is this crop's version of the brewery sorghum deal
Traders/aggregators	Farm-gate cash, price follows the mills minus margin	The flexible channel; your scale and moisture discipline claw back margin
Town food trade	Soy milk/flour/chunks makers, roasters, households	Smaller tonnage, better prices; white-hilum clean grain where preferred
Seed niche	Fresh tested seed at planting season	Module 5's premium — small volumes, best margins
Your own livestock	Roasted/cooked soy + your maize = home-mixed rations	The Poultry/Piggery courses' feed-cost revolution — never raw

Lesson 6.2 — An honest one-hectare budget

Item	Assumption	Amount
Yield	Inoculated improved seed, full stand, two weedings, rattle-date harvest	~1.8 t
Gross	$0.40–0.60/kg to mills/traders (food/seed niches above this)	~$720–1,080
Seed (70–90 kg) + inoculant (double sachet)	fresh certified + the few-dollar yield multiplier	$70–130
P fertiliser (+ lime where sour)	SSP/compound at planting	$60–140
Labour + optional rust spray + sundries	weedings, harvest ON TIME, threshing gear, sacks, transport	$140–280
Indicative margin	plus nitrogen left for next maize	~$450–650/ha — before the rotation bonus is counted

Lesson 6.3 — The rotation bonus, counted

The honest soybean ledger adds a line most budgets forget: the following maize crop's saved nitrogen (often the equivalent of a bag or more of urea) and its measurable yield bump on soybean land. When the pair is planned together — same feed-mill buyer for both grains, machinery and labour shared, legume nitrogen banked — the SYSTEM margin beats either crop alone. This is why the course's business plan is written for the maize–soybean pair, not soybean solo.

Lesson 6.4 — Records and the growth path

Per plot per season: variety, seed source and germination result; inoculation details (product, expiry, storage) and the 4–6 week nodule score (pink/white/none); stand count at 3 weeks; weeding and any spray dates; rattle date vs harvest date (the shattering meter); yield, splits estimate and moisture at sale; price and channel; the following maize's yield on this land. Report card: nodule score, stand count, and the rattle-to-harvest gap. Growth path: year one — one inoculated hectare done exactly right; year two — the maize–soybean pair with a contract registration and hermetic seed stock; year three — group tonnage on contract, the seed-sales niche, and home-mixed rations feeding your own poultry or pigs.

📺 Watch it done: From collection point to home-mixed ration — the pair that beats either crop alone. Open curated video search → The written lesson above is complete on its own — the video is optional reinforcement.

Practical Assignment — Month 6: Build the one-hectare budget from your recorded costs and local prices; then extend it to the SYSTEM budget: add next season's maize on this land with its nitrogen saving and expected bump. If a contract scheme exists, obtain its registration requirements and spec sheet; if not, interview two traders on grades and price seasonality. Cost a small home-ration trial (roasted soy + your maize) against bought feed for the livestock you keep or plan. Conclude with your year-one/two/three path in one paragraph.

Month 6 Quiz — 10 Questions

Answer every question. Aim for at least 7/10 before marking this month complete. Each answer comes with an explanation — read them even when you are right.

1. Contract/outgrower soybean schemes offer:

Why: Industrial buyers organise supply like the breweries organise sorghum: register early, read the spec before planting, and deliver on grade.

2. The spec lines contracts grade on include:

Why: Module 5's disciplines priced: dry honestly, thresh gently, winnow clean — the three numbers that decide whether the truck accepts your sacks at full price.

3. Feeding your own soybean to poultry or pigs requires:

Why: The heat rule follows the bean into the ration. Properly cooked soy plus home maize is the feed-cost revolution the livestock courses point at.

4. The rotation bonus in the soybean ledger is:

Why: A bag-of-urea equivalent left in the soil plus a measurable maize response: the system margin is the true bottom line, which is why the plan is written for the pair.

5. The three report-card numbers are:

Why: Nitrogen working, population achieved, shattering beaten — the season's three decisive acts, each reduced to one honest recorded figure.

6. The seed-sales niche rewards:

Why: Soybean seed's fragility is the careful grower's moat: a germination certificate at planting week outsells any sack of hope.

7. Group tonnage matters to mills because:

Why: The sorghum-contract lesson repeats: one clean store, one scale, one moisture discipline, many farmers — and the truck comes to you.

8. The year-one goal of this course is:

Why: Intensity before area, the college's constant law: the skills proven on one hectare multiply safely onto every hectare that follows.

9. Soybean's town food trade prefers:

Why: Milk, flour and chunk makers pay above commodity for quality they can see — a premium side channel beside the contract anchor.

10. This course's business plan is written for:

Why: Shared buyer, shared calendar, banked nitrogen: the pair is the unit of profit. Planning them together is the module's parting instruction.

Market case: your channel map (mill/contract, traders, food trade, seed niche, own rations) with real terms and specs, and the variety chosen for it with maturity and daylength fit.
Establishment plan: seed source and germination protocol, the full inoculation procedure with product handling rules, P (and lime) programme, and the population plan with target stand count.
Season calendar: planting window, weeding dates, nodule-check date, water-watch weeks, rust scouting routine with spray trigger, and pod-pest thresholds.
Quality war plan: the splits-greens-moulds commitments — harvest trigger, gentle threshing method, drying targets with the stop rule, and store checks.
Harvest and stocks: the rattle-date booking system (labour or thresher), ground-loss measurement, and the two-stock separation with the seed stock's hermetic rules and premium sales plan.
System budget: the hectare budget plus the following maize's nitrogen saving and yield bump — the pair's margin as one number; cash-flow across both seasons.
Risk page and year-3 vision: three risks with mitigations, and the staged path — one perfect hectare, then the pair with contract registration, then group tonnage, seed sales and home-mixed rations.

Submission standard: A plan you could hand to a savings group, a bank officer, or a family investor without embarrassment. Real local prices, real named buyers, honest risks.

💰 Startup Budget — 1 Hectare Inoculated Soybean (within the Maize–Soybean Pair)

Soybean's budget turns on three small purchases used exactly right — fresh seed, the inoculant sachet, and phosphorus — plus discipline at the shattering clock. The final line belongs to the system: the nitrogen this hectare banks for next season's maize is real money this sheet credits explicitly.

Item	Details	Typical cost (USD)
Fresh certified seed (70–90 kg)	Germination-tested; released for your latitude band	$55–100
Inoculant (double sachet, new land)	Cool-kept, in-date — the yield multiplier	$8–25
P fertiliser (SSP/compound) + lime where sour	The nodulation package's other half	$60–140
Land preparation & planting labour	Warm moist seedbed, dense drilling	$70–150
Weeding labour ×2	Shallow, on the 2–3 and 5–6 week clock	$40–100
Optional rust fungicide + sprayer access	Triazole at first pustules where justified	$20–60
Harvest & threshing on the rattle date	Morning labour, tarpaulins, flexible sticks / thresher hire	$60–140
Drying & storage gear	Racks/tarpaulins, sacks, pallet, hermetic seed container	$30–80
Transport to collection point		$25–70
Contingency (10%)		$35–85
Total indicative startup	Plus the nitrogen credit banked for next season's maize	$405–950

Prices vary widely by country. Before spending anything, price every line in your own town and rebuild this table — that exercise is part of your final project.

📚 Glossary

Rhizobium (soybean-specific): The specialist nitrogen-fixing bacterium most African soils lack — supplied on the seed via inoculant.
Inoculation: Coating moistened seed with live rhizobium powder in shade and planting within hours — the course's highest-return act.
Nodule score: The 4–6 week dig-and-cut check: pink-red inside = working; white/none = rescue N and diagnose.
Promiscuous varieties: African-bred soybeans that nodulate with native rhizobia — the no-inoculant fallback.
Population crop: A crop yielding on plant numbers: 300,000–400,000/ha, dense rows, pods set higher.
Daylength sensitivity: Flowering triggered by day length — why varieties are bred for latitude bands and planted in released windows.
V and R stages: The leaf (vegetative) and flowering-to-maturity (reproductive) stage ladder used to time every decision.
Asian soybean rust: The explosive defoliating disease scouted on lower-leaf undersides from flowering; fought with tolerance, earliness and timed triazoles.
Green bridge: Volunteer plants carrying disease between seasons — destroyed to make rotation real.
Shattering: Dry pods twisting open and firing seed to the ground — the reason harvest is booked against the rattle date.
Rattle date: The day seeds rattle in browned pods (~13–15% moisture): the harvest clock's start.
Splits: Cracked seed from rough threshing or over-drying — the number-one grade cut.
Anti-nutritional factors: Compounds in RAW soybean harmful to people and livestock — destroyed by proper roasting or boiling.
Hermetic seed stock: The fragile seed lot kept airtight, cool and untouched — next season's stand and the planting-week premium.
Outgrower scheme: A processor's contracted farmer network with specs, prices and collection points — soybean's anchor channel.
Rotation bonus: The nitrogen and yield bump soybean banks for the following maize — the pair's hidden margin line.
