Abstract:
Community level physiological profile (CLPP) assays, which assess a microbial community, has the capacity to metabolize specific sole carbon sources for study of environmental soil samples. Analysis of soils after ten years of application of different organic manures and inorganic fertilizers under cotton-wheat cropping system at CCS H.A.U Hisar shows that there was a buildup of higher microbial functional diversity than those in conventional farming systems. In this study, we made an attempt to find out the effect of organic manuring and integrated nutrient management on microbial communities and BIOLOG assay. Functional microbial diversity on the basis of sugar and amino-acid utilization pattern was also studied in these soils and it was found that in inorganically fertilized, integrated managed and organically manured soils formed two different groups indicating the different microbial activity in these treatments.
