The possibility of a win-win for farmers and the environment is a driving force for the soil health movement. It is a management philosophy centered around four simple principles: reduce or eliminate tillage, keep plant residues on the soil surface, keep living roots in the ground, and maximize diversity of plants and animals.
If nature has not been optimized by any process that we know of, and therefore consists of mostly random mixes of species dictated primarily by natural disturbances, then there is no reason to “follow nature’s lead.” But if we don’t, what are we left with?
We are left with an agriculture based on human ingenuity.
