Effect of anthropogenic activities on soil microbiota.

The soil microbiota is conformed by microorganisms present in the soil such as bacteria, fungi, algae, protists and archaea, mainly, which have a fundamental role in the mineralization and mobilization of nutrients, as well as in the protection of plants against pathogens, in addition to establishing mutualistic interactions in the rhizosphere. Therefore, microbiota play an important role in soil productivity, quality and structure. The objective of this bibliographic review was to Know the effect of anthropogenic activities on soil microbiota. From the review it was found that anthropogenic activities such as the use of agrochemicals, fires, erosion or change in land use have negatively affected the soil microbiota. There is evidence of a decrease in the diversity and abundance of microbial populations, in addition to the reduction or inhibition of the activity of microorganisms. This directly affects the functions of the microbiota (microbiome), since different microbial taxa influence soil physicochemical characteristics, biogeochemical cycles and plant population dynamics, although it is essential to conduct more exhaustive research to identify the effect of human activity.
