Knowledge Base — Coverage Map

John Seymour's curriculum, mapped clean-room to Sproutopia's engines.
Internal planning artifact Clean-room · own words Source: Seymour (not reproduced)
← Product Docs · KB Coverage Map

Purpose. A functional coverage map of the curriculum in John Seymour's The Complete Book of Self-Sufficiency (258 pp.), 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. The source PDF (full-self-sufficiency.pdf, project root) is a local planning reference only — never deployed, never in the AI grounding corpus (NFR-17), and should be 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.
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

Seymour topic Sproutopia home Disp. Notes
The living farmyard (integration of animals) Livestock engine (§4.7), Closed Loop Feeds the manure→soil loop.
Cow; making butter & cream; making cheese Livestock + Cellar (dairy crafting) Dairy → Cellar crafting tree. Cheese aging = real cellar timers.
Beef, goats, pigs, sheep, rabbits Livestock evolutions/branches (FR-21/22) Life-cycle timings, husbandry tasks, branch decisions (dairy vs meat).
Poultry (layers/meat) Livestock (flagship animal for beginners) Likely the first animal for Megan; layer vs meat branch.
Bees & honey Bees engine (§4.9) Colony management, honey as loot, pollination aura.

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) Out of v1: hunting/trapping/firearms beyond a gardening app's scope & liability.
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

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)

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
