Effect of Continuous Use of Chemical Fertilisers and Manures on Soil Physical and Chemical Properties

Continuous use of FYM helped in maintaining and improving physical properties and organic matter content of the soil but failed to give higher yields in a permanent manurial experiment. On the contrary, the nitrogenous fertiliser slightly deteriorated soil physical properties but gave higher yield due to higher availability of N. The role of phosphatic fertilisers in improving soil physical properties is commendable. It has been concluded that if N fertiliser is used in combination with P and K plus FYM, higher yields can be obtained without causing any deterioration of soil physical properties.
