I have been reading Nicole Masters book “For the love of Soil” She has given me a new understanding the power of the right biology for the desired out come. Any studies on soil biology and how it relateds to changes in the soil and plant health could be very beneficial. There is much to learn in this area. What systems (crops, plants, animals, inoculants, stimulants, or management disruptions) change the soil biology and what are the effects. This is a big subject that is very exciting to me.
