The rainfall in India is variable in intensity, duration and distribution. High-intensity storms often result in large amounts of rainfall excess (runoff), particularly in soils such as the Vertisols where infiltration rates are low. Runoff causes large amounts of soil erosion annually, resulting in the degradation of the crop production potential of the soil resource. Proper management of the Vertisols results in many benefits. A system of graded broadbeds and furrows has been developed at ICRISAT which improves surface drainage in the monsoon season (facilitating rainy season cropping), allows runoff to occur at non-erosive velocities and permits it to be collected in storage facilities. The broadbed-andfurrow system also facilitates reapplying the water to the crops during stress periods.
