Abstract
Current management practices in crop production by using excessive chemical fertiliser and pesticide have significant impact on soil organism populations and their activities. Community level physiological profiles CLPP have shown their potential as a relevant method to characterise soil microbial community diversity. This study was done to assess the short term response of microbial community diversity to organic amendment and biofertiliser application in the conventional agricultural practices area. Biolog EcoPlate„ system was used to assess the microbial activity and community-level physiological profile. Fertilisation influenced the average wellcolour development AWCD in the first week where most of the treatment except treatments 0 0D 0.46 nm and F 0D 0.34 nm enhanced the AWCD especially treatment C. This indicated that fertilisation influence microbial metabolic diversity and carbon-mineralisation. Only a few substrates were highly utilised 0D0.50 such as Putrescine L-Asparagine L-Serine L-Arginine D-mannitol I;J-Acetyl-DGlucosamine Cellobiose D-Galacturonic Acid D-Malic Acid Pyruvic Acid Methy Ester Glucose-1-Phosphate Tween 40 and Tween 80. Richness R was generally decreased for all treatment as compared to control. This showed that microbes in the treated soil oxidised lower carbon substrates as compared to control. Based on Shannon Weaver Diversity index there were no significant differences between every treatment for all weeks. This indicated that all treatments have a more or less the same catabolic diversity.
