- Abstract
The different types of soil and climate in the Northeast region of Brazil are an important factor for livestock exploitation, and consequently, there is a predominance of forage crop cultivation, making it important to study species that can be used by producers. The objective was to evaluate the alteration of soil microorganism diversity after anthropogenic interference in natural vegetation for land use as pastures in the southern region of Piauí. An area of 300 m² was selected for the collection of seven simple soil samples at a depth of 10 cm. Microbiological parameters were evaluated: percentage of colonization and taxonomy of Arbuscular Mycorrhizal Fungi (AMF), basal respiration, extraction of total glomalin (GT) and easily extractable glomalin (GFE) fractions, determination of soil carbon sources (CLPP), and statistical evaluation of data using analysis of variance (ANOVA) and Tukey's test (5%). The cerrado forest showed the highest diversity of AMF compared to systems cultivated with forage grasses. The microbial community present in the soil of treatments containing grass cultivation and native cerrado forest consumed different types of carbon sources, indicating variability of microorganisms in the rhizosphere of these ecosystems.
