Is application of fertilizers harmful to the soil/ plants/ humans ?
Fertilizer applications at the recommended rates are not at all harmful. It is wrong to carry such doubts to the farmers and the consumers of farm products. Fertilizers carry the similar chemical elements which a soil or atmosphere contain. Secondly, the raw materials used for manufacturing fertilizers are natural products. For example, the air we breathe contains 79% nitrogen and is used to manufacture nitrogenous fertilizers like urea. Natural minerals like sulfur, rock phosphate are used to manufacture phosphatic fertilizers like super phosphate.
