Abstract
In the semiarid
tropics (SAT) regions, the loss of soil, organic matter, and nutrients are of great concern. Nutrient imbalance in the
case of major plant nutrients has been reported for a long period of time as a result of decline in soil organic carbon status in the
rainfed areas of Asia and SubSaharan
Africa. In India, the results of analysis of a large number of soil samples collected from farmers
fields in Andhra Pradesh, Karnataka, Madhya Pradesh and Rajasthan, showed that the samples were low in organic carbon, low to
medium in available phosphorous (P), medium to high in potassium (K), low in sulphur (S), boron (B) and Zinc (Zn).
