WHAT IS GOING ON WITH OUR SOILS?

What is going on with our soils and why is there a perception amongst farmers that they have to use higher rates of fertilisers to get the same results they used to get 40 years ago? The answer to both these questions is intrinsically linked and lies in the soils – specifically soil chemistry and soil biology. Clearly, soils are not performing like they used to despite a shift to reduced tillage, better rotations, controlled traffic, and so on. To understand what is going on, we have been looking at the science behind two key issues, namely nitrogen and organic matter in the soil.
