INFLUENCE OF ORGANIC MANURES AND FERTILIZERS ON SOIL MICROBIAL BIOMASS-C, N AND P

The field experiment was undertaken to investigate the influence of organic manures and fertilizers on soil microbial soil microbial biomass-C, N and P. The research was conducted at ZARS, GKVK, Bangalore. There were 10 treatments and three replications in an RCBD design. The treatment contains different levels of organic manures like 5t, 10t, 12.5t, 15t, 17.5t and 20t fertilizers like 25%, 50%, 75% and 100%. Soil microbial biomass C, N and P were analysed in different treatments and these were found to be significantly higher in the treatment with application of 20t of FYM ha-1 compared to recommended NPK alone
