The water desk goes all the way down to the level of fifty cm below soil surface area during dry intervals and soil pH falls to three-4 leading to acid sulphate condition. Hitherto several efforts have already been manufactured to ameliorate the paddy lands but no any affordable Resolution is received. The Nationwide Science Foundation undertaking to learn the feasibility of making use of organic hydraulic forces to extend drinking water table to keep the acid sulphate forming minerals at bay and to cultivate rice in these paddy lands. Water desk fluctuation in relation to drinking water degree inside the drainage channel was researched above 1 year and there was found a very high correlation (r2=0.
Appropriately, the Minister emphasised that the final determination During this regard will be taken at the Cabinet meeting because of be held up coming week.

Extreme and continuous use of nitrogen and phosphorous fertilizers for many years have transformed the agricultural soils into Digital chemical time bombs. Phosphate rocks by their very geological and mineralogical character comprise a bunch of environmentally hazardous chemical features like Cd, Pb, Hg, U Cr and As among Other individuals. The superphosphates are especially considerable in these harmful features and they contaminate the agricultural soils throughout the use of fertilizer.
