Abstract
Agronomic practices markedly influence the characteristics of the soils leading to changes in their microbial communities and, consequently, in ecosystem functioning and productivity. We evaluated the long-term effect of three tillage systems (no tillage - NT-, minimum tillage -MT- and conventional tillage -CT-) and two cropping systems (monoculture and rotation) on the microorganisms in a soil under semi-arid climate. For this purpose, we assessed by quantitative polymerase chain reaction (qPCR) the abundance of universal genetic markers to identify total communities of bacteria (16S ribosomal RNA) and fungi (internal transcribed spacer, ITS). We performed Pearson?s rank correlation and backward multiple-linear regression analyses to identify the relationship between these biological markers and physical-chemical and biochemical soil attributes. Under both cropping systems, bacteria were more abundant in plots under MT whereas fungi dominated under NT. NO3-N concentration was among the parameters that had the greatest influence on the microbial markers.
