When soil structure fails, the soil literally collapses into compacted layers at depth and crusted soil at the surface. In order to reverse this downward trend in soil carbon, soil aggregate stability, and overall soil function, we must reverse the way the soil has been managed. Restoring soil carbon, soil structure, and soil function won’t happen overnight, but it can happen in as little as a few years. As soil function is restored, the methods of assessing the soil must change as the soil changes. He is also the author of “A Soil Owner’s Manual: How to Restore and Maintain Soil Health.”
