Speedy development of agriculture is vital to the progress of our country. For securing maximum crop production, the best use of available land has to be made and the latest methods of crop husbandry are to be put into practice. A field study was carried out to analyze the short term impacts of replacing mineral by organic fertilizers on the microbial and biochemical parameters relevant for soil fertility and crop yield. Three types of fertilization regimes were compared: (1) conventional fertilizer regime with inorganic fertilizer, and combined integrated fertilizer regimes in which 25 % of the nutrients were supplied by either (2) rabbit manure or (3) vermicompost. The effects on microbial community structure and function (phospholipid fatty acid [PLFA] profiles, bacterial growth, fungal growth, basal respiration, β-glucosidase, protease and phosphomonoesterase activities), soil biochemical properties (total C, dissolved organic carbon [DOC], N-NH4+, N-NO3−, PO4, total K) and crop yield were investigated in the samples collected from the experimental soil at harvest 3 months after addition of fertilizer. | | Keywords : | | - Sustainable agriculture PLFAs and Soil enzymes
