Abstract

Nowadays, one of the most important challenges is to ensure sustainable agricultural management of crops such as maize (Zea mays L.). Long-term crop production, however, may influence the soil properties, the composition and activity of microbial communities. The aim of this study was to compare the catabolic activity and taxonomic diversity of bacterial communities inhabiting the soil of a non-fertilized maize monoculture and a natural grassland. Samples were taken from the horizons A and C in the first part of the vegetation period. MicroResp™ technique was used to explore the catabolic potential of microbial communities and next generation amplicon sequencing to reveal the bacterial diversity. Based on the catabolic activity results, higher differences were revealed among the soil horizons than the different land uses. The highest degree carbon source utilization was detected in the soil horizon A of the natural grassland. The taxonomic composition of bacterial communities was dominated by Proteobacteria. The relative abundance of other dominant phyla (Acidobacteria, Bacteroidetes, Verrucomicrobia, Actinobacteria, Planctomycetes, Gemmatimonadetes, Chloroflexi and Patescibacteria) varied according to both the land use and soil depth. Amplicon sequences belonging to genera of r-strategist "copiotrophic" and K-strategist "oligotrophic" bacteria were identified from the soils of both maize monoculture and grassland.
