Soil

Soil is the foundation the rest grows from, and on worn-out farmland it is usually the first thing to fix and the slowest. Healthy soil is alive — fungi, bacteria, insects, worms — and fungi are the easiest to overlook though whole ecosystems lean on them (protected areas overlook fungi, study).

Non-negotiables​

  • Test before you treat: texture, chemistry, contamination.
  • Feed the soil life, don't sterilise it; disturb as little as possible.
  • Build organic matter; track change across years, not months.

Options & pathways​

  • Living cover and mulch — almost always; keep the ground covered. Cheap, needs material. Mixed cover crops feed soil microbes and balance nutrients (mixed cover crops for soil health, news).
  • Compost and amendments — for depleted ground you can feed; limited by supply.
  • Fungal and microbial support — when planting into broken ground; needs the right fungi (plant–mycorrhiza synergy).
  • Minimal- or no-till — protects structure and life; sometimes slower to establish.

Even bare sand can be rebuilt from almost nothing with microbial crusts (soil crusts on degraded land, news).
