Effect of Integrated Nutrient Management Practices on Distribution of Nitrogen Fractions in Soil

A field study was carried out at College of Agriculture, Navile, Shimoga during Kharif 2009 to study the effect of integrated nutrient management practices on distribution of nitrogen fractions in soil. There were two levels of nitrogen applied through organics (FYM and vermicompost) and inorganics involving nine treatments combinations were tried in a RCBD with three replications. Significantly lower available nitrogen status was recorded in the treatments which received nitrogen only through fertilizers and without any organic matter application (196.00-200.50 kg ha^-1) including absolute control compared to all other treatments (238.00-243.60 kg ha^-1). Except inorganic nitrogen fractions, organic nitrogen fractions were recorded high in integrated treatments compared to the treatment which received nitrogen only in the form of fertilizers.
