Abstract
The present study was undertaken to observe the effects of chemical fertilizers and compost amendments on microbial community structure in rice based cropping system under long term fertilizer application experiment. Changes in microbial community structure assessed by the relative abundance of fatty acid methyl ester (FAME) profiles revealed that compost amendments led to promoting the abundance of Gram-positive bacterial FAMEs. Multivariate analysis of FAME profiles separated the treatments primarily on the basis of the amount of added compost. A link between different fertilizer application treatment and soil microbial components was tentatively established, but it needs to be verified in further studies.
