Effect of different organic sources on biochemical properties in typical inceptisols of Jammu

A pot experiment was conducted during Kharif 2005 to ascertain the response of different organic sources viz Wheat Straw, Farmyard Manure, Vermicompost and Poultry Manure on biochemical properties viz microbial biomass carbon (MVC), microbial biomass nitrogen (MBN), and microbial biomass phosphorous (MBP) and dehydrogenase activity. Poultry Manure and vermicompost treated soil coupled with NPK resulted in higher MBC as compared to manure treatment. Soil MBP and MBN also increased with the application of wheat Straw, poultry Manure, FYM and vermicompost respectively over control. Similarly the soils showed higher dehydrogenase activity with incorporation of poultry manure, vermicompost, FYM and wheat straw respectively over control.
