Integrating Chemical and Microbial Soil Indicators for Effective Erosion Stabilization in the Atlantic Forest

Abstract

Soil erosion in the Atlantic Forest biome, particularly within gully systems, is a significant environmental challenge affecting biodiversity, ecosystem function, and land productivity. Erosion control and stabilization in these areas have become a key focus for land conservation and restoration strategies. This study examines the chemical and microbial attributes of soils as indicators of erosion stabilization in gully systems of the Atlantic Forest biome in Brazil. Soil samples were collected from both eroded and stabilized gully sites across different regions within the biome. Chemical parameters, including pH, organic matter content, cation exchange capacity (CEC), and levels of nitrogen (N), phosphorus (P), and potassium (K), were analyzed. Microbial activity was assessed through the measurement of soil respiration, microbial biomass, and enzymatic activities (e.g., dehydrogenase, phosphatase). The results revealed that soils in stabilized gully areas exhibited higher organic matter content, improved chemical fertility, and higher microbial activity compared to eroded sites. These findings suggest that the chemical and microbial health of soils can serve as reliable indicators for monitoring the success of erosion stabilization in gully areas. The study highlights the importance of integrating chemical and biological soil indicators into erosion control and land management practices in the Atlantic Forest.
