Title Using Rainfall Excess for Supplemental Irrigation of Vertisols in India
 
Creator Krishna, J H
 
Subject Watershed management
Agriculture-Farming, Production, Technology, Economics
 
Description 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.
