Use of brackish water and its impacts on soil fertility and wheat crop in Kachho, Sindh, Pakistan
Abstract
In the Northwest of Sindh, due to the absence of River and irrigation water, the brackish water of Right Bank Out Fall Drain (RBOD) has remain the basic source for irrigation since last ten years. The use of brackish water of RBOD for agriculture purpose, direct impacts on the pH, TDS and EC of the Soil. For the laboratory purpose, soil samples were collected from disturbed parts of research area where a white layer of the salt crust has been exposed out. Average analytical results showed that pH level was 8.2, EC was7.2 dsm-1and TDS of 3580ppm. The samples were collected at depth at of depth of 0–15, 15-30 and 30-45cm to find out the depth of salts in soil. The study area is wheat growing region; the study showed that 13.3%, 27.8%, 40.6%and 55.6% productivity has been reduced in 2011, 2012, 2013 and 2014 cropping years respectively.
