Improving soil health on farm fields integrates the three types of soil management: physical, chemical, and biological. Physical management includes how farmers use their equipment on fields – tilling, harvesting, etc. Chemical management involves the timing and choice of fertilizers, manure, and other additions. Soil biology is the next frontier being researched for optimizing soil … Continue reading What is the current research about soil additions to help soil biology?
