This study assessed the structural changes in fungal and bacterial communities in soils under integrated croplivestock systems, comparing six rainfed plots with four center-pivot irrigated quadrants and a neighbor native forest. All plots were managed under crop rotations with palisade grass (Urochloa brizantha), upland rice, soybean, maize, and maize + pasture intercropping. Soil samples collected in 2015 and 2016 were analyzed by Terminal Restriction Fragment Length Polymorphism. Canonical analyses of principal coordinates using Bray-Curtis dissimilarity indices showed that the microbial communities were differently influenced by the land use (rainfed, irrigated, or forest) and the crop. The results with the AluI endonuclease in 2015 showed that the fungal community structure shifted according to the treatments (cropped plants) and soil moisture. In 2016, there were overlapping fungal communities in rainfed and irrigated plots with less evident responses to the cultivated crop. There was a clear separation between bacterial communities in rainfed and irrigated areas in both years, but no clear distinction was found between crops within a management system. There was a higher overlap of important (0.4 > mean relative abundance) fungal T-RFs in rainfed and irrigated plots samples for two enzymes. In contrast, there was a higher overlap of bacterial T-RFs between irrigated areas and forest. The results suggest that crop-livestock integrated management increased soil fungal diversity compared to the native vegetation, while this shift in diversity was not clear for bacteria. The diversity increase and the fungal community's response to crop rotations may be linked to reports of soil suppressiveness to soil-borne fungal pathogens.
