備土

察土況、過修、堆、生力備立健活土也。

  • 起新畦察現土→用
  • 植弱即水光足(土為因)→用
  • 自常轉有機或生力→用
  • 土壓、瘠、拒水→用
  • 立堆系→用
  • 施生力備(500-508)→用

  • :可至土(畦、田、缽)
  • :今土試果(pH、N-P-K、有機 %)
  • :園史(前作、施修、年)
  • :欲種作
  • :徑偏(有機、生力、永續)

一:察土

三場試無需室——皆行。

Test 1: Jar Test (Texture — Sand/Silt/Clay Ratio)
1. Fill a quart jar 1/3 full with soil from 15cm depth
2. Fill to top with water, add 1 tablespoon dish soap
3. Shake vigorously for 3 minutes, then set on level surface
4. Read layers after settling:
   - Sand settles in 1 minute (bottom layer)
   - Silt settles in 4-6 hours (middle layer)
   - Clay settles in 24-48 hours (top layer)
5. Measure each layer as % of total soil depth
   - Ideal garden soil: ~40% sand, ~40% silt, ~20% clay (loam)

Test 2: Spade Test (Structure and Compaction)
1. Push a spade into moist soil to full depth (25cm)
2. Lever up a block of soil and place on a board
3. Observe:
   - Crumbles easily → good structure
   - Breaks into angular blocks → compacted
   - Smears or is sticky → too much clay or waterlogged
   - Layers visible → hardpan or plough pan present
4. Smell the soil:
   - Sweet, earthy → healthy aerobic biology
   - Sour, sulphurous → anaerobic conditions (drainage problem)

Test 3: Earthworm Count (Biological Activity)
1. Dig a 30cm × 30cm × 30cm cube of soil
2. Place on a tarp or board
3. Gently break apart and count earthworms
   - 0-5: Poor biology — needs organic matter
   - 5-10: Fair — improving but not yet thriving
   - 10-20: Good — healthy biological activity
   - 20+: Excellent — this soil is alive

得:明知土質、構、生。瓶試果、構評、蚓數。

敗:瓶層難分→重以清水力搖。蚓 0 且土酸→恐厭氧——修前必處排。

二:診計修

對察果於修計。

Hot Compost Protocol:
1. Build pile in layers — 2 parts brown (carbon) to 1 part green (nitrogen)
   - Brown: dried leaves, straw, cardboard, wood chips
   - Green: kitchen scraps, fresh grass, manure, coffee grounds
2. Moisten each layer (damp sponge consistency)
3. Pile must be at least 1m × 1m × 1m to reach temperature
4. Internal temperature should reach 55-65°C (130-150°F) within 3-5 days
5. Turn pile when temperature drops below 45°C (every 5-7 days)
6. After 3-4 turns, cure for 2-4 weeks without turning
7. Finished compost: dark, crumbly, smells like forest floor, no recognizable inputs

Never Compost:
- Meat, dairy, oils (attract pests)
- Diseased plant material (unless hot compost reaches 60°C+ for 3 days)
- Treated wood, glossy paper
- Pet waste (pathogen risk)

得:堆系立、首批進中。

敗:熱堆不熱:察濕(過乾或過濕)、察 C:N(增綠為氮)、察堆大(<1m³ 不熱)。

四:施無耕與覆作

護土構而不翻。

No-Till Sheet Mulching (New Bed from Lawn or Weeds):
1. Mow or scythe existing vegetation as low as possible
2. Layer cardboard (overlapping edges) directly on ground — no gaps
3. Wet cardboard thoroughly
4. Add 5cm compost on top of cardboard
5. Add 10-15cm organic mulch (straw, wood chips, leaves)
6. Wait 3-6 months (autumn application → spring planting)
7. Plant through mulch by pulling it aside — do not till

│                 │                │ compaction                    │

│                 │                │ winter (bio-drill)            │
└─────────────────┴────────────────┴───────────────────────────────┘

Terminate cover crops by:
- Crimp and roll (best — leaves roots in place)
- Scythe and lay as mulch
- Never rototill — this destroys the soil structure you're building

得:土年護、生不擾、有機增。

敗:覆作不立→察播深(多需面或淺播)與濕。重播或厚覆代。

五:生力備(可——進)

為循 Demeter 或生力者。

Preparation 500 Application:
1. Stir 100g horn manure in 35 litres warm water
2. Stir dynamically for 1 hour — create vortex, reverse, create vortex
   (alternating direction every minute)
3. Apply within 1 hour of stirring
4. Spray in large droplets on soil surface — late afternoon, descending moon
5. Apply autumn (before winter) and early spring (before sowing)

Note: Biodynamic preparations are available from certified suppliers
or local biodynamic farming groups. Making your own requires the
previous season's preparations and specific animal horn sheaths.

得:備施於正時與月相。土生活見於 1-2 季。

敗:備不得→善堆與覆作得 80% 生益。備增非代妥土管。

六:癒點——修後察

修後六週、重察土。

Post-Amendment Soil Health Check:
1. Repeat the spade test:
   - Has structure improved? (Crumbles more easily)
   - Are roots penetrating deeper?
   - Any remaining hardpan layers?

2. Repeat the earthworm count:
   - Has the count increased? (Even 2-3 more is progress)
   - Are worms distributed through the depth or just at surface?

3. Drainage test:
   - Dig a 30cm hole, fill with water, let drain, refill
   - Second fill should drain within 1-4 hours
   - <1 hour: very free draining (may need more organic matter)
   - >4 hours: still compacted or clay-heavy (continue treatment)

4. Surface observation:
   - Fungal threads visible in mulch layer? (Good — decomposition active)
   - Green algae on surface? (Too wet or too compacted)
   - Mulch layer breaking down? (Biology is working)

Triage:
- All improving → Continue current approach, reassess next season
- Structure improved but worms low → Add more diverse organic matter
- Worms present but drainage poor → Broadfork again, add coarse material
- No improvement → Soil may have contamination — consider lab test for heavy metals

得:3 指(構、生、排)至少 2 量化進。

敗:6 週後無進→事恐深於頂土修可治。計築高畦含購土混為並策、續多季改地土。

  • 三場試畢(瓶、鍬、蚓)
  • 自試果正診土型
  • 修計合診況
  • 堆系立(熱、冷、蚓)
  • 土年覆(覆、覆作、活植)
  • 無翻耕或土反
  • 修後 6 週癒點行
  • 園誌更於試果與所施修

  1. 不試而加:隨修費錢可加亂。必先試
  2. 翻耕:似產而破土構、殺蚓、引草籽至面。若必鬆用寬叉
  3. 裸土:露土失濕、構、生。必覆或植覆作
  4. 鮮糞於畦:燒根引病。諸糞必堆 ≥6 月乃接土
  5. 未試 pH 而灰:過灰致養不可用。唯按實試果調 pH
  6. 期速果:建土以季年計、非週

  • cultivate-bonsai — 盆栽土混(赤玉/輕石/熔岩)為專土備
  • plan-garden-calendar — 修土時合季曆(秋灰、春堆)
  • read-garden — 土察為園讀則之分
  • heal — 修後察循癒分類式
  • forage-plants — 解土植關助野植境讀
  • make-fire — 火灰為傳土修(鉀+灰)
