Effects Of Water Table Management Practices On The Transport Of Nitrates In Sandy Underground Environment

Enhancing the degradation of agrochemical pollutants by managing the water table has introduced a new horizon in agricultural pollution control. Experimental work in this area shows that the degradation of agrochemicals such as nitrate is dependent on the soil water content. The aim of this study...
