Crop rotation reduces the frequency of anaerobic soil bacteria in Red Latosol of Brazil.

Braz J Microbiol 2021 Jul 28. Epub 2021 Jul 28.

ABC Foundation, Rod. PR 151 km 288, Caixa-postal: 1003, Castro, PR, CEP 84165-700, Brazil.

Crop diversity affects the processes of soil physical structuring and most likely provokes changes in the frequencies of soil microbial communities. The study was conducted for soil prokaryotic diversity sequencing 16S rDNA genes from a 25-year no-tillage experiment comprised of two crop systems: crop succession (Triticum aestivum-Glycine max) and rotation (Vicia sativa-Zea mays-Avena sativa-Glycine max-Triticum aestivum-Glycine max). The hypothesis was that a crop system with higher crop diversification (rotation) would affect the frequencies of prokaryotic taxa against a less diverse crop system (succession) altering the major soil functions guided by bacterial diversity.
