USDA-NRCS is rolling out a new soil health campaign according to No-Till Farmer. NRCS has been preaching soil health for 20 years. I am looking forward to see if there is anything new. Healthy soil is definitely important. Practices that keep soil healthy also lead to higher yields. It is all about a healthy root zone. There is a myth that healthy soil means organic farming. Organic farming is not necessary. Another idea is that no-till is needed to keep soil healthy. I have seen healthy soils maintained using a number of techniques. Some of them are simple.
