Efficacy of long-term integrated plant nutrient management on important soil properties of an Inceptisol

摘要

A long-term field experiment conducted since 1972 on Vertic Ustropept indicated that application of 10 t ha~(-1) of farmyard manure along with 100 per cent NPK recorded significantly lower bulk density. Farm yard manure application with 100 per cent inorganics increased the hydraulic conductivity, water stable aggregates, porosity and water holding capacity. There was increase in CEC, organic carbon and total N content of soil due to incorporation of organics with inorganics. There was no marked changes in soil pH and EC due to various treatments. Available major and micronutrients increased significantly when organics was incorporated along with inorganic sources of nutrients.
