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. In 23–44% of EU and UK farmland the organic carbon in the soil is at high risk of loss, mostly in cool, humid regions (soil carbon at risk in Europe ✓, news). 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. Full recovery takes decades: restored grasslands needed 75+ years of management to match ancient grassland plant diversity, and pollinators lag behind even that (grassland recovery takes 75+ years ✓, news).

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.
  • Hedgerows and field margins — wherever there are field edges; slow to establish, then permanent. Soil under hedgerows held about 40% more carbon than neighbouring grassland across England, and older hedges hold more (hedgerows store 40% more soil carbon ✓, news); they also connect habitat.

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