ABSTRACT

In this paper we discuss the impact on conversion degraded pasture areas into an integrated
crop, livestock and forest system (ICLFS). We collected 30 soil samples at 0-0.1 m depth in
five agroforestry systems, degraded pasture and native areas along Brazilian Cerrado biome.
We analyzed the influence of chemical variables on microbial biomass carbon and enzyme activity
using multivariate statistic analysis. The land use explained only the variation of microbial
biomass carbon and seasonality explained the variation in glycine aminopeptidase activity.
The sample controls differ from the other soil areas due to their greater biological activity (MBC).
The enzymatic indicators showed that the biological activity is lower in degraded pasture. It was
observed that the ICLFS system had a positive effect on the microbial activity (MBC and soil
enzyme) when compared to pasture. This reinforces the importance of adopting more sustainable
practices to improve soil quality.
