Activity of soil microbial biomass altered by land use in the southwestern Amazon Bragantia
Mazzetto,André Mancebo; Cerri,Carlos Eduardo Pellegrino; Feigl,Brigitte Josefine; Cerri,Carlos Clemente.
ABSTRACT The increasing demand for food creates environmental problems, mainly due to the removal of native vegetation cover for agriculture expansion in Brazil. These changes in land use lead to changes in the soil organic matter dynamics. Microorganisms represent the most biological and physiological diversity in soil, as well as are responsible for more than 95% of the decomposition and nutrient cycling processes. The objective in this research was to check if there is difference of patterns in activity of soil microbial biomass under varied natural vegetation, pastures in use and agricultural systems recently established. The area covered by this study corresponds to the states of Rondônia and Mato Grosso. Canonical variate analysis was used in...
