Combined application of inorganic fertilizers (NPK) along with either 25% N or 50% N substitutions through FYM registered higher value in soil physico-chemical properties than recommended dose of NPK and biofertilizer based INM package. Integrated treatment receiving 50% of NPK along with 50% N through FYM resulted lower value for bulk density and higher values for mean weight diameter and water stable aggregates after rice-niger sequence. Organic carbon content and pH of the surface and sub-surface soils were found to be maximum in treatments involving either 50 or 75% of NPK along with FYM. In surface soil, application of 50% of NPK along with 50% N of FYM exhibited significantly the highest value of CEC after harvest of rice. 收起
