The integrated biological soil cycle shows how much fertile soil relies on microbial activity

The integrated soil-plant biological cycle starts/ends with soil organic matter, and is entirely mediated by soil microbes (and soil animals) yet appears destined to serve nutrients to plants and CO2 to capture sunlight.

Will Brinton speaks about the inportance of soil biology for healthy soils with high yielding crops at theNo-Till Alliance in Pennsylvania last summer

The way nature does it – the carbon dioxide cycle in simple steps

  1. PLANTS may require up to 500 lbs of CO2 per day per acre, making carbon the single largest nutrient (but ignored in modern farming).
  2. SOIL can supply up to 300 lbs/day as CO2- the less the more depleted soil is.
  3. ROOT respiration also supplies more CO2 to the soil system respiring similarly to soil microbes.
  4. AIR: Theoretically, to satisfy the CO2 needs for 1 acre of wheat 10 cubic acres of air are needed (but much less if the soil is healthy).
  5. ALL: Under whole-healthy conditions, the soil-plant cycle is a unified self-contained oxygen-CO2-nutrient system.
