A field study entitled Soil biological properties as influenced by long term application of organic and inorganic inputs under wheat-maize cropping system in typic haplustepts was conducted during Kharif 2016-17 and 2017-18 in the Long Term Fertilizer Experiments initiated in Kharif, 1997 at the Instructional Farm of the Rajasthan College of Agriculture, Udaipur. The results of the present investigation revealed that the significantly highest microbial population (i.e Bacteria, Fungi and Actinomycetes) were registered in FYM @ 20 t treatment followed by 100% NPK + FYM 10 t ha-1. Application of inorganic fertilizer alone or combination with manure significantly improved microbial population as compared to control and 100% N treatment. However, highest Azotobacter population was found in 100% NPK + Azotobacter treatment followed by FYM @ 20 t treatment. The maximum content of soil microbial biomass carbon, soil microbial biomass nitrogen, soil microbial biomass phosphorus and soil microbial biomass sulphur were registered under application of FYM @ 20 t in LTFE soils. Application of either manure (FYM) alone or in combination with inorganic fertilization significantly improved microbial biomass as compared to inorganic fertilization alone.
