Soil microbiome analysis of Uruguayan grasslands and croplands reveals losses of microbial diversity and necromass recycling traits.

ABSTRACT:

Background

Soil microbiomes are critical regulators of nutrient biogeochemical cycles, contributing significantly to ecosystem services that support plant productivity. In this study, we investigated the effects of agricultural rotations on soil microbial communities in Uruguayan grasslands, comparing cropland soils with native grasslands grazed by livestock. By employing advanced metagenomic techniques, we characterized the diversity and functional potential of the soil microbiome, with particular emphasis on its roles in carbon, nitrogen, and phosphorus cycling. Additionally, we assessed functional genes associated with microbial necromass recycling, a key process for maintaining soil health and fertility.

Results

Our analysis revealed a significant decrease in fungal dive
