As you gain more experience, you can change the recipe. The fungal energy pathway and the microbiome; Christine cites some of the papers presented at the Wageningen Soil Conference we wrote about here, emphasising that the early model of the soil food web is beginning to be replaced by a new, more dynamic model.Previous models of the soil carbon pathway were fairly linear, with carbon entering the soil through breakdown of above ground matter and . The roots of cover crops prevent erosion and reduce compaction, and their presence encourages more beneficial microbes in the soil.

Drying-wetting cycles can also help restore porosity in soils containing clay minerals that swell when they are moistened and shrink when they dry. Some good cover crops for compacted soils are hairy vetch, red clover, and hairy sorghum. In a study in Georgia, tall fescue sod was terminated by moldboard plowing or glyphosate application (no-till) and converted into annual crop production. Soil that is left bare may bake in the sun and become impermeable or, in wet conditions, stormwater run-off will carry away the valuable topsoil.
