The banana bowl in Khandesh, Citrus zone in Varhad and cotton/ cereal crops belt in all north eastern Maharashtra witness nitarte contamination in underground water as these soils are routinely fertilized with heavy dosages of nitrogenous fertilizers. Thus, the bulky doses of the fertilizers for the past five decades (since 1970s) have been resulted into (i...
