Carbon is the currency of nature: the backbone of soil organic matter and the energy source for soil microorganisms. Therefore, much interest in soil health focuses on increasing carbon storage in soil. When you reduce tillage or increase crop rotation diversity, you expect soil organic matter to increase. However, soil organic matter often changes slowly for several years. In fact, less than 1% of plant biomass carbon returned to soil eventually becomes stable humus organic carbon.
Soil health is the cornerstone of balanced crop nutrition. Up to 60% of yield is dependent on soil fertility. Setting the foundation for healthy soils provides greater crop productivity and sustains the land for generations to come.
