Complete Plowing, Soil Preparation, and Field Management Guide
All agriculture begins with breaking ground. The plow is the tool that transforms wilderness into farmland. This campaign covers plow construction, draft animal use, soil types, and field preparation for maximum yield.
Chapter 1: Plow Types and Applications
| Plow Type | Draft Power | Depth | Best Soil | Complexity | Era |
|---|---|---|---|---|---|
| Digging stick | Human | 2-4 inches | Light, sandy | None | Prehistoric |
| Foot plow (chakitaqlla) | Human | 6-8 inches | Any | Low | Ancient |
| Ard (scratch plow) | 1 ox or horse | 3-6 inches | Light, dry | Low | 3000 BC+ |
| Moldboard plow | 2 oxen or 1 horse | 6-12 inches | Heavy, clay | Moderate | Medieval |
| Chisel plow | Tractor or 4+ oxen | 12-18 inches | Compacted, hardpan | Moderate | Modern |
| Disc plow | Tractor | 6-10 inches | Sticky, rocky | High | Modern |
| No-till (direct seed) | None (hand or drill) | 1-2 inches | Any (with mulch cover) | Low | Modern sustainable |
Chapter 2: Draft Animal Power
| Animal | Pull Force | Acres/Day | Endurance | Feed Required | Training Time |
|---|---|---|---|---|---|
| Ox (single) | 150-200 lbs | 0.5-0.75 | 6-8 hours | Grass/hay (low cost) | 2-4 weeks |
| Ox (pair/yoke) | 300-400 lbs | 1-1.5 | 6-8 hours | Grass/hay | 2-4 weeks |
| Horse (draft) | 200-300 lbs | 1-2 | 4-6 hours | Grain + hay (higher cost) | Months |
| Mule | 175-250 lbs | 1-1.5 | 8-10 hours | Hay + some grain | Months |
| Water buffalo | 200-300 lbs | 0.75-1 | 6-8 hours | Grass, wetland forage | 2-4 weeks |
| Human (with hoe) | 30-50 lbs | 0.1-0.25 | 4-6 hours | Food | N/A |
Oxen advantages over horses: cheaper to feed (grass only, no grain), stronger for heavy pulling, calmer temperament, easier to train, can be eaten when retired. Horses are faster but require grain and more skill.
Chapter 3: Soil Types and Management
| Soil Type | Texture | Drainage | Fertility | Workability | Best Crops |
|---|---|---|---|---|---|
| Sandy | Gritty, loose | Excellent (too fast) | Low (nutrients leach) | Easy (light to plow) | Root crops, melons |
| Loam | Balanced, crumbly | Good | High | Ideal | Everything (best soil) |
| Clay | Sticky, heavy | Poor (waterlogged) | High (holds nutrients) | Difficult (heavy, sticky) | Rice, wheat (when drained) |
| Silt | Smooth, flour-like | Moderate | High | Moderate | Vegetables, grains |
| Peat | Dark, spongy | Poor | Very high (organic) | Easy when drained | Vegetables, berries |
| Chalky | White, rocky | Excellent | Low-moderate | Moderate | Grapes, lavender |
Soil improvement: Sandy → add clay and organic matter. Clay → add sand and organic matter. All soils → add compost, manure, and cover crops annually. The goal is always loam (balanced mixture).
Chapter 4: Field Preparation Calendar
| Season | Action | Purpose | Tools |
|---|---|---|---|
| Fall (after harvest) | Primary plowing (deep, turn soil over) | Buries crop residue, exposes pests to frost | Moldboard plow |
| Fall | Spread manure/compost on plowed field | Nutrients decompose over winter | Wagon, fork |
| Early spring | Secondary plowing (lighter, break clods) | Prepares seedbed | Ard or disc |
| Spring | Harrow (drag frame with teeth/chains) | Levels field, breaks clods, kills weeds | Harrow frame |
| Spring | Roll (heavy roller) | Firms seedbed, ensures seed-soil contact | Stone roller |
| Planting | Furrow (shallow trench for seed) | Creates planting row | Plow or hoe |
| Growing | Cultivate between rows | Kills weeds, aerates soil | Hoe or cultivator |
| Post-harvest | Cover crop (plant rye, clover, vetch) | Prevents erosion, adds nitrogen, builds soil | Broadcast seed |
Chapter 5: Building a Simple Plow
| Component | Material | Function | Specification |
|---|---|---|---|
| Beam (main frame) | Hardwood (oak, ash) 6-8 feet | Connects to draft animal | Straight, strong |
| Share (cutting blade) | Iron or steel, pointed | Cuts soil | Sharpened, replaceable |
| Moldboard (turning surface) | Iron, steel, or hardwood | Turns soil over | Curved surface |
| Handles (stilts) | Hardwood, 3-4 feet | Operator control | Two handles for steering |
| Coulter (vertical blade) | Iron/steel disc or knife | Cuts ahead of share | Optional but helpful |
| Landside (flat plate) | Iron/steel | Stabilizes plow in furrow | Runs along furrow wall |
| Clevis (hitch) | Iron | Connects beam to draft chain | Adjustable height/angle |
Simplest plow: Forked tree branch (one branch = beam, other = share). Sharpen the share end. Attach to ox yoke with rope. This is the ancient ard — it scratches soil rather than turning it, but it works.
Chapter 6: Crop Rotation (Four-Field System)
| Year | Field 1 | Field 2 | Field 3 | Field 4 |
|---|---|---|---|---|
| 1 | Wheat/grain | Root crops (turnips, potatoes) | Legumes (clover, beans) | Fallow (rest) |
| 2 | Root crops | Legumes | Fallow | Wheat/grain |
| 3 | Legumes | Fallow | Wheat/grain | Root crops |
| 4 | Fallow | Wheat/grain | Root crops | Legumes |
Why rotate: Grain depletes nitrogen. Legumes ADD nitrogen (bacteria on roots fix atmospheric N₂). Root crops break up compaction. Fallow allows recovery. Continuous monoculture = soil death within 3-5 years.
Reference Card
- One pair of oxen plows 1-1.5 acres per day (enough for a family's grain needs in 5-10 days)
- Oxen are cheaper than horses: eat grass only, stronger pull, calmer, easier to train
- Always plow in fall (deep) and spring (shallow): fall buries residue, spring prepares seedbed
- Rotate crops: grain → roots → legumes → fallow. Never plant same crop twice in same field.
- Add organic matter every year (compost, manure, cover crops): builds soil, increases yield
- Simplest plow: forked branch sharpened at tip, pulled by ox. Upgrades from there.
- Loam is ideal soil: improve sandy soil with clay+compost, improve clay with sand+compost
- Cover crop in fall (rye, clover): prevents erosion, adds nitrogen, suppresses weeds
