DAN348 - Long term management of wheat rotations to sustain soil fertility and crop productivity
In south east (SE) Australia, grain growers are facing large scale degradation of soil chemical, biological and structural fertility which has largely been the result of past inappropriate management practices over a long time. Issues of concern to the industry include declining soil organic matter, total nitrogen (N), soil pH, soil structure and soil biology. Most of these attributes change slowly over time and long term studies of trends are required to accurately and scientifically ascertain the effects of these practices.
