Abstract/Description: | Groundwater is the major or the only source of supplemental irrigation in the arid, semi-arid and coastal regions. Poor quality irrigation water in shrink–swell soils (i.e. Vertisols or black cotton soils) causes poor drainage (due to low saturated hydraulic conductivity (sHC)), increase in pH (due to soil reaction), high exchangeable sodium/magnesium percentage and increase in bulk density of soil. Therefore, quality of irrigation water is a key issue in irrigated agriculture, particularly in black soils where due to high clay content of the shrink–swell type of soil, the drainage problem is more likely. In India, shrink–swell soils (Vertisols) developed in the alluvium derived from the weathering of Deccan basalt, are found mostly in the Peninsular region extending from 845N to 260N lat. and 680E to 8345E long. Majority of shrink–swell soils (Vertisols) covering nearly 76.4 mha (ref. 3) in India occur in the lower piedmont plains or valleys, or in microdepressions. |
