Purpose. A functional coverage map of the curriculum in John Seymour's self-sufficiency system, extracted as facts/methods/scope only and mapped to Sproutopia's engines. This drives KB scope and epics. It is authored in our own words; no Seymour prose or illustrations are reproduced here or in the product.
Source editions (both project-root PDFs, planning reference only). Primary reference is now the 2018 US revised edition — The Self-Sufficient Life and How to Live It (the-self-sufficient-life-...pdf, 410 pp., DK 2018; foreword by Alice Waters) — cross-checked against the earlier Complete Book of Self-Sufficiency (full-self-sufficiency.pdf, 258 pp.). The 2018 edition is more food-focused (it drops the older traditional-crafts chapters), which reinforces the ⛔ scope calls below. Publisher caveat (adopt as a hard KB signal): DK's "A Note on the Text" states Seymour's text is his 1970s writing with only minimal changes, and flags with asterisks the pesticide/chemical and peat recommendations that are no longer recommended or available. → Policy: any asterisk-flagged item is REMOVED entirely from the KB — not carried forward, not caveated, not shown as "no longer valid." We simply omit it; where a control or growing medium is still needed, we author fresh modern guidance from scratch (§8.4 IPM; peat-free media). Corroborates NFR-11 / NFR-16. Both PDFs are local planning references only — never deployed, never in the AI grounding corpus (NFR-17), and git-ignored if this becomes a repo.
Disposition legend: ✅ v1 KB · 🕓 roadmap/secondary-persona · ⛔ out of scope for Sproutopia · ⚠️ integrate only after modernization/safety review.
Two layers: §1–§7 map Seymour's curriculum (options 1 + 2). §8 is our own researched additions — modern methods and post-1970s knowledge Seymour lacks or gets dated on (option 3), with the authorities to build from in §9. All content is authored clean-room in our own words.
1. The Way to Self-Sufficiency — first principles
| Seymour topic (functional) | Sproutopia home | Disp. | Notes |
|---|---|---|---|
| "High Farming" — the balanced loop where plants feed animals, animals' manure feeds soil, soil feeds plants; species rotated so each gives/takes | Closed Byproduct Loop (§4.12), Knowledge Base rules | ✅ | This IS our closed-loop thesis. Seymour's "High Farming" validates the whole product spine. Ground the loop mechanics here. |
| Crop rotation — don't grow one family repeatedly on the same soil; rotate to balance soil needs & break disease | Beds engine / Self-Collision (§4.5), KB rules (FR-19) | ✅ | Direct source of the Tron rotation-trail guardrail. Plant-family data + rotation windows. Concrete cycle to author from (2018 ed., "Vegetables through the Year"): a 4-plot loop — Plot A potatoes (heavily manured) → B legumes/brassicas (limed after potatoes) → C roots (no fresh manure) → D miscellaneous / green-manure fallow — rotating one step each year, greenstuff carried through winter by brassicas + leeks. This is the canonical rotation sequence + seasonal task template for the Calendar (FR-11/32) and confirms the Beds trail order. |
| Soil fertility & husbanding the land ("heart" of the soil) | Soil-Life View (FR-4), Beds nitrogen charge (FR-16) | ✅ | Modeled soil life; compost/manure raising fertility. |
| Planning by land size — the One-Acre Holding | Digital Twin onboarding + starter plan (FR-3), Ambition Level | ✅ | Directly supports "plan scoped to your space." Beginner/backyard tier. |
| The Five-Acre Holding (larger mixed smallholding) | Ambition Level (advanced), secondary persona | 🕓 | Beyond Megan's half-acre v1 front door; useful for the active homesteader path. |
| Biodiversity / leaving wild areas / interaction of species | Biodiversity Score (FR-47) | ✅ | Whole-system health, beneficials, hedgerows. |
2. Food from the Fields — field-scale crops & grassland
| Seymour topic | Sproutopia home | Disp. | Notes |
|---|---|---|---|
| Grains (wheat, barley, oats, rye, maize), sowing→harvest→threshing | — | 🕓 | Field-scale; beyond a half-acre backyard v1. Roadmap for larger holdings. |
| Grassland, hay, silage | Livestock (feed) | 🕓 | Feed context for larger livestock; light KB reference only in v1. |
| Larger livestock on field scale (working the land) | Livestock engine | 🕓 | Overlaps §3 Food from Animals; field-scale husbandry is roadmap. |
Whole part is largely 🕓: the field/acreage-scale content serves the secondary "active homesteader," not Megan's first season.
3. Food from Animals
Breed/variety data lives in
animals.json(rendered at/breeds) — 75 breeds across cattle, goat, pig, sheep, chicken, duck, goose & rabbit, each with purpose, size, temperament, pros/cons, beginner-suitability, and Livestock Conservancy conservation tier, so users choose their animals by real tradeoffs. It expands well beyond Seymour's ~25 breeds (his originals are flagged). Verified at the NFR-16 gate (nfr16-verification.md). The husbandry rows below are the KB authoring reference for the Livestock engine.
| Seymour topic | Sproutopia home | Disp. | Notes |
|---|---|---|---|
| The living farmyard (integration of animals) | Livestock engine (§4.7), Closed Loop | ✅ | Feeds the manure→soil loop. |
| Cow (dairy/beef/dual-purpose); butter, cream & cheese | Livestock + Cellar (dairy crafting), KB rules (FR-19) | ✅ | Dairy → Cellar crafting tree; cheese aging = real cellar timers. Husbandry to author: classes dairy/beef/dual-purpose; breeds — Jersey (small "family cow," richest milk, tractable, poor beef), Friesian/Holstein (big, heavy dairy, good beef calves), Red Poll / Danish Red / dual-purpose Shorthorn (dual), Hereford (beef), Brown Swiss (longevity, high-protein/fat milk for cheese). 1 calf/year to keep milking; ~10-month lactation; dry off ~8 wks pre-calving; milk 2×/day at ~12-hr intervals. Buy-checks: TT (tuberculosis) + brucellosis tested (often legally required), udder for mastitis/blind quarters, age by teeth. Feeding: maintenance + production ration (hay ~12–20 lb/day Jersey→Friesian; ~3.5 lb concentrate per gallon over the first; seaweed/minerals). Health: mastitis (common), brucellosis, TB, grass staggers (hypomagnesemia) → ⚠️ modernize vet guidance via Extension. |
| Goat (small-holding/garden dairy) | Livestock (FR-21/22), Cellar (goat cheese), KB rules | ✅ | The garden-scale dairy animal — efficient roughage→milk converter; milk suits cow-milk-allergic, superb cheese (small fat globules). Breeds: Nubian (rich milk, lower volume), Toggenburg (small Swiss, lives on grass), Saanen (large, high yield). Chief challenge = containment: 3-strand electric (15/27/40 in) or 4-ft chain-link; wire netting useless. Feeding: doe 3–6 pints/day; ~2 lb hay/day + roots + grain + salt lick (needs real feeding, not grass alone). Housing: not winter-hardy, hate rain — airy draft-proof shelter. Dry off 8 wks pre-kidding; can milk 2–3 yrs without re-kidding. Castrate billy kids by 3 mo (Elastrator rings) or meat turns gamey. Bonus: goat-milk orphan-rearing for calves/piglets/foals. |
| Pig (the "free cultivator" + closed-loop keystone) | Livestock (FR-21/22), Closed Loop (§4.12), KB rules | ✅ | Best all-round converter; clears/plows/manures land behind a movable electric fence — a closed-loop keystone (eats scraps/whey/surplus, makes meat + compost). Feeding: barley/corn meal + protein supplement (whey/skim milk/fish/bean/soy — animal protein/B12 essential for milking & late-pregnancy sows); roots/veg unrestricted; creep-feed piglets from ~3 wks; restrict concentrates after ~100 lb (half-grown) to avoid over-fat; twice-daily "15-minute rule." Sows: ~2 lb/day concentrate on grass → ~6 lb at farrowing. |
| Sheep (meat + wool) | Livestock (FR-21/22), KB rules | ✅ | Meat + wool (+ milk in places). Breeds: Dorset Horn (can lamb twice a year), Border Leicester (prolific; mutton + wool), Southdown (very small → good for a small family). Small-flock catch = tupping (a ram is uneconomic under ~6 ewes → borrow / take ewes to a farmer's ram; raddle/marker to track service). Stocking ~5 sheep = 1 bullock; ~5 lambs/acre; graze pasture rested 6+ mo (parasites). Mating: flush (poor→good pasture) before tupping; ram serves up to 60 ewes; gestation 147 days; lamb late Feb–Mar; cull old ewes by teeth; fat lambs ~4 mo on spring grass. |
| Rabbits (domestic meat/fur husbandry) | Livestock engine (FR-21/22), KB rules (FR-19) | ✅ | Farmed rabbits are in scope — a distinct topic from "rabbits as game" (§5, ⛔). Ch 3 gives full husbandry: breeds (New Zealand White, Californian for meat/fur; Flemish Giant too large → crossing only); breeding cadence (gestation ~30 days, wean ~8 wks, re-breed ~6 wks post-kindling, doe re-kindles ~17 days after litter removal, sex-separate at 3 mo); yield (2 does + 1 buck → ~200 lb/yr); portable-shelter/paddock/hutch housing (cold-tolerant, wet/heat-averse, nest box); feeding schedules. Strong beginner-scale animal; a good first-animal alongside poultry. |
| Poultry / chickens (layers/meat) | Livestock (flagship beginner animal), KB rules (FR-19) | ✅ | Likely Megan's first animal (layer vs meat branch). Husbandry to author: must have outdoor range (welfare + disease avoidance) + dust-baths (mites); ~¼ of food + protein from grass. Dual-purpose heritage breeds that lay, go broody, hatch, and make table birds: Rhode Island Red, Barred Plymouth Rock, (Columbian) Wyandotte, Light Sussex, Cuckoo Maran (hardy, deep-brown eggs) — commercial hybrids won't go broody. Feeding: summer grass + grain; winter protein supplement (soy must be cooked; or fish/meat/bean meal); greens from 10 days; grit/crushed seashell for shell; layer/chick/fattening mash recipes as reference. Systems: free-range (house till noon to collect eggs), limited-grass strip rotation, Balfour method (straw yard + rotated grass pens — ideal for small backyards). Housing: mobile coop, perches with clear droppings fall, dark rat-proof nesting boxes, broody coop for sitting hens. ⚠️ Pair with modern backyard-chicken guidance (biosecurity, predator-proofing, local ordinances — see §8.5). |
| Bees & honey | Bees engine (§4.9), Cellar, KB rules | ✅ | Colony management, honey as loot, pollination aura. Hive types: old straw skep vs Langstroth movable-frame (the "bee space" discovery) — teach Langstroth. Honey as a sugar substitute (~⅔ the quantity); rent-a-hive for pollination income. ⚠️ Safety (NFR-11): never give honey to infants under 12 months — infant botulism risk (surface wherever honey appears in Cellar/recipes). Modern Varroa mite IPM is the critical post-Seymour gap — see §8.5. |
4. Food from the Garden — the beginner core
| Seymour topic | Sproutopia home | Disp. | Notes |
|---|---|---|---|
| The food-producing garden; the gardener's tools | Beds, KB reference cards (FR-18) | ✅ | Core beginner content. |
| Sowing & planting; growing under cover; the greenhouse | Beds, Calendar (FR-11), KB timings | ✅ | Season/timing rules feed the Calendar. |
| Protecting from pests | Vision AI diagnosis (FR-8), KB hazards | ✅ | Modernize with IPM; pair with Vision AI. |
| Vegetables; herbs | Beds, KB entity cards, Apothecary (herbs) | ✅ | Per-crop reference data (spacing, timing, hazards). |
| Vegetables through the year (Winter/Spring/Early & Late Summer/Autumn) | Weather-aware Calendar (§4.4), seasonal chapters (FR-32) | ✅ | Backbone of the seasonal task calendar. ⚠️ UK-centric seasons — must generalize to the user's zone/frost dates (FR-1), not hard-code his calendar. |
| Soft fruit; tree fruit; caring for fruit trees | Orchard engine (§4.8) | ✅ | Pruning, pollination partners, multi-year care. |
| Storing fruit & vegetables | Cellar/Pantry (§4.11), Larder | ✅ | Root-cellaring, cold storage. |
| Preserving; bottling; pickles & chutneys; jams & syrups | Cellar crafting (FR-33/34) | ⚠️ | Food-safety critical (NFR-11). Seymour's 1970s bottling/canning times predate modern botulism/pressure-canning standards — do NOT teach his preservation times; use current tested (USDA/NCHFP-equivalent) standards. Method concepts fine; times/temps must be modern. |
| Making wine; cider & vinegar | Cellar (brewing branch), real timers | ✅ | Fermentation concepts; note alcohol/legal + hygiene. |
5. Food from the Wild
| Seymour topic | Sproutopia home | Disp. | Notes |
|---|---|---|---|
| Plants, nuts & berries (foraging) | Foraging/Wild layer (FR-51) | ✅ | Map wild edibles/medicinals; seasonal prompts. ⚠️ Add strong "positive-ID / don't eat unknowns" safety framing. |
| Game (hunting/trapping — incl. wild rabbits) | — | ⛔ | Out of v1: hunting/trapping/firearms/ferreting beyond a gardening app's scope & liability. NB: this is the wild-rabbit-as-game frame only — farmed/domestic rabbit husbandry is fully in scope under §3 Livestock (✅). Don't let the hunting exclusion drop farmed rabbits. |
| Fish & sea foods | — | ⛔ (foraging shellfish 🕓) | Fishing largely out; shellfish/wild foraging roadmap with heavy safety caveats. |
6. Natural Energy
| Seymour topic | Sproutopia home | Disp. | Notes |
|---|---|---|---|
| Saving energy | Self-Sufficiency Score (FR-46) inputs | 🕓 | Ledger context; conceptual only in v1 (food-first). |
| Power from water / sun / wind | — | ⛔ (v1) | Hardware/infrastructure — out of v1 (aligns with deferred soil-sensor hardware). Roadmap for the Self-Sufficiency vision. |
| Fuel from waste / composting waste | Closed Loop (FR-37), compost → soil | ✅ | The waste→resource loop concept is core; biogas hardware out. |
7. Crafts & Skills
| Seymour topic | Sproutopia home | Disp. | Notes |
|---|---|---|---|
| Natural medicine / herbal remedies (herbs thread) | Apothecary branch (FR-36) | ✅ | Functional herbalism; ⚠️ "not medical advice" framing (already flagged §9.1). |
| Wells, ponds & fish farming | — | 🕓 | Water/infrastructure; roadmap. |
| Basketry, pottery, spinning, weaving, flax, curing & tanning, bricks & tiles, stone, metal, building & thatching, woodwork, household items, the all-purpose furnace | — | ⛔ | Traditional homestead crafts — outside Sproutopia's food-and-growing scope for v1 (and roadmap). Not KB content. |
8. Beyond Seymour — modern KB additions (our research)
Seymour's book is 1970s UK. These are the topics a modern, beginner-first, US-capable KB needs that he lacks, gets dated on, or predates entirely. Authored clean-room from the authorities in §9.
8.1 Soil & bed methods (modernize his double-dig era)
| Addition | Why (gap vs. Seymour) | Sproutopia home | Disp. |
|---|---|---|---|
| No-dig / no-till (compost mulch on top, minimal disturbance) | Seymour is double-dig; modern soil-health practice is no-dig — less work, better soil life, fewer weeds. Beginner-friendly. | Beds, Soil-Life View | ✅ |
| Square-foot / intensive spacing (grid; 1/4/9/16 plants per sq ft) | Gives beginners exact, foolproof spacing — directly answers "what goes where, how far apart." | Beds spacing data, KB cards, beginner Ambition | ✅ |
| Raised beds & container / small-space growing | For Megan's patio containers & side yard; Seymour is land-scale. | Beds, Twin | ✅ |
| Cover crops / green manures & mulching | Modern soil-building between crops. | Beds, Closed Loop | ✅ |
| Soil testing (pH / NPK / micronutrients) & interpretation | Modern amendment decisions; grounds the Soil-Life model. | Soil-Life View (FR-4), KB | ✅ |
| Space-value / "plants with attitude" — rank each crop by return per unit area for small/urban gardens (avoid space guzzlers: maincrop potatoes, corn, winter squash, asparagus; prioritize salads, tomatoes, pole/runner beans, carrots, soft fruit, herbs); make the most of all three dimensions (vertical/trellis) | Beds recommender (small-space steering), KB cards | ✅ | Seymour's Urban-Garden guidance, now captured as a small_space_value (high/medium/low) field on every crop in plants.json. Directly answers Megan's "what's actually worth growing in my tiny space." |
8.2 Climate, zones & timing (localization Seymour can't give)
| Addition | Why | Sproutopia home | Disp. |
|---|---|---|---|
| USDA Plant Hardiness Zone map (2023 update, 1991–2020 data) + last/first frost-date databases | The zone/frost backbone of the Twin. Note: zones = winter survival; frost dates = when to plant — different things. ~half the US shifted a warmer half-zone in 2023. | Digital Twin (FR-1), Calendar | ✅ |
| Season extension (row covers, low tunnels, cold frames — Coleman four-season) | Modern materials/methods to stretch the season. | Calendar, Weather quests, greenhouse | ✅ |
| Climate-adaptation (drought resilience, shifting frost dates) | Post-1970s reality Seymour couldn't foresee. | Weather engine, Calendar | ✅ (concept) |
8.3 Seed starting (fixes Megan's exact failure — the leggy grow-light seedlings)
| Addition | Why | Sproutopia home | Disp. |
|---|---|---|---|
| Grow-light discipline (14–16 h/day; light 2–4 in above tops; fan for airflow; avoid hot soil) → prevents leggy seedlings | This is literally Megan's documented failure ("grow light used once, seedlings got leggy and died"). Highest emotional payoff in the KB. | Winter War-Room Feb seed-starting (FR-44), Calendar | ✅ |
| Hardening off (~2-week gradual outdoor acclimation) | The step beginners skip → transplant shock. | FR-44, Calendar | ✅ |
8.4 Pest & disease — modern IPM
| Addition | Why | Sproutopia home | Disp. |
|---|---|---|---|
| Integrated Pest Management (monitor → thresholds → beneficials/row covers → least-toxic escalation) | Modernizes Seymour's 1970s, pesticide-forward pest chapter; pairs with Vision AI. | Vision AI (FR-8) + KB hazards, Beds | ✅ |
| Evidence-based companion planting (separate tested benefits from folklore) | Beds/adjacency buffs must be grounded, not myth. | Beds, KB | ✅ |
8.5 Livestock & bees — post-1970s knowledge
| Addition | Why | Sproutopia home | Disp. |
|---|---|---|---|
| Varroa mite IPM (sugar-roll/alcohol-wash monitoring, <3% threshold, screened bottom boards, drone-brood removal, oxalic/formic acid in broodless windows, resistant genetics) | Varroa reached the West after Seymour's book — a total gap. The single most important modern beekeeping topic; our Bees frame-photo Vision AI already targets it. | Bees engine (§4.9), Vision AI | ✅ |
| Modern backyard chickens (biosecurity, predator-proofing, coop ventilation, local ordinances, vaccination) | Seymour's poultry is farm-scale; Megan needs backyard-scale, legal-aware guidance. | Livestock (§4.7) | ✅ |
| Native pollinators beyond honeybees (pollinator strips, nesting habitat) | Broadens pollination + biodiversity beyond hives. | Bees, Biodiversity Score | ✅ |
| Modern livestock health (parasite management, vaccination schedules, antibiotic stewardship) | Updates his veterinary guidance. | Livestock, KB | 🕓 |
8.6 Preservation & food safety — modern tested standards (SAFETY-CRITICAL, NFR-11)
| Addition | Why | Sproutopia home | Disp. |
|---|---|---|---|
| USDA/NCHFP tested method rules — water-bath for high-acid (pH<4.6: fruit, acidified tomatoes, pickles); pressure canning for low-acid (vegetables, meats) to reach ≥240°F and kill C. botulinum spores | This is the authority that replaces Seymour's unsafe 1970s numbers. Botulism is fatal. | Cellar (FR-35), NFR-11 | ✅ (mandatory) |
| Altitude adjustments (water-bath +1 min/1000 ft above 1000 ft; pressure: raise PSI per elevation on a tested gauge) | Missing/dated in Seymour; safety-critical. | Cellar, FR-35 | ✅ |
| Modern methods he underweights — freezing, dehydrating, lacto-fermentation (kraut/kimchi) safety, freeze-drying | Broadens the Cellar beyond canning. | Cellar | ✅ |
8.7 Water, waste & apothecary
| Addition | Why | Sproutopia home | Disp. |
|---|---|---|---|
| Drip irrigation / water-wise / rainwater harvesting / mulching for moisture | Modern efficiency; Seymour minimal. | Beds, Calendar, Self-Sufficiency | ✅ (concept) |
| Modern composting (hot composting, vermicomposting, bokashi for kitchen scraps) | Powers the scraps→soil loop & the Livestock upsell CTA. | Closed Loop (FR-37) | ✅ |
| Herbal-remedy safety (evidence level, drug interactions, contraindications, not-medical-advice) | Guards the Apothecary branch. | Apothecary (FR-36) | ✅ (safety) |
9. Authorities & sources for KB authoring
Build the KB from these (facts, methods, tested standards — all safe to author from in our own words). Not reproduced; cited so the content team knows the canonical references.
- Food safety (mandatory): USDA Complete Guide to Home Canning / National Center for Home Food Preservation (NCHFP, UGA); USDA FSIS on C. botulinum. — [the source for all preservation times/temps].
- Zones & frost: USDA Plant Hardiness Zone Map (2023) + frost-date databases.
- Soil & beds: no-dig (Charles Dowding); square-foot / intensive spacing (Mel Bartholomew); university Cooperative Extension services (soil testing, cover crops).
- Season extension: four-season methods (Eliot Coleman).
- Pest/IPM & beekeeping: land-grant university Extension IPM guides; Varroa IPM (Penn State / Virginia Tech Extension, etc.).
- General: Cooperative Extension is the go-to US authority for region-specific, tested guidance — a strong, safe backbone alongside Seymour's methods.
Headline findings (for the PM / KB epics)
- Seymour's "High Farming" is our closed-loop thesis, stated plainly. Ground the Closed Byproduct Loop and Beds rotation directly in his first-principles chapter — it's the strongest fidelity anchor and the brand's honest lineage.
- The garden + seasonal calendar + animals + preserving map almost 1:1 onto our beginner core (Beds, Calendar, Livestock, Bees, Cellar). This is where ~80% of usable v1 KB content lives.
- Two hard safety gates before any preserving/foraging content ships (NFR-11): (a) replace all of Seymour's preservation times/temperatures with modern tested standards — teach his methods/concepts, never his 1970s canning data; (b) add positive-ID/toxicity safety framing to foraging.
- Localize, don't transcribe, his calendar. His seasons are UK-centric; drive timing from the user's zone/frost dates (FR-1), using his structure (what to do each season) not his dates.
- Clear scope line: the field-scale (grains/acreage), energy-hardware, and traditional-crafts parts are 🕓/⛔ for v1 — Sproutopia is food-and-growing first. Good "not now" boundaries for the KB.
- Fidelity is achievable and safe: everything ✅ above is functional method/scope (not protectable); authored clean-room in our words it fully satisfies "built on Seymour's teaching" without touching his expression.
- Seymour is the foundation, not the ceiling (§8). The KB should pair his methods with modern researched content he lacks — no-dig, square-foot spacing, IPM, USDA zones/frost, modern food-safety standards, and especially Varroa management (which post-dates his book entirely). Cooperative Extension + NCHFP are the safe modern backbone.
- Two additions are disproportionately high-value for Megan: (a) grow-light seed-starting discipline directly fixes her documented failure (leggy seedlings); (b) square-foot spacing answers her core "what goes where" paralysis. Prioritize both in the beginner KB.
