Effect of continuous application of organic and inorganic sources of nutrients on chemical properties of soil

Continuous applications of organic manures and inorganic fertilizers have been reported to affect soil pH, electrical conductivity, Soil organic carbon, available N, P and K. Electrical conductivity has been used as chemical indicator of soil biological quality in response to crop management practices. Continuous application of organic manure and inorganic fertilizer decreased soil pH but increased total soluble salt concentration. Soil organic carbon, available N, available P; and water soluble, exchangeable and total K were significantly increased with the conjoint application of organic manure and inorganic fertilizer whereas the concentration of non-exchangeable K was significantly decreased with combined application of organic manure and inorganic fertilizer in comparison to application of fertilizer alone. Thus the use of organic and inorganic sources of nutrients improved chemical properties of soil, ultimately soil health and productivity.
