Abstract
Most of the soils of tropical countries are affected by erosion processes. As a result, much attention has been dedicated to the use of microorganisms to improve the geotechnical properties and stability of soils in the context of “bioengineering”. This work was carried out to analyze the effects of the use of a CaCO3 precipitating nutrient on native microbiota with the aim of mitigating the erosion processes in a tropical soil profile. We observed that the use of nutrient B4 enabled native bacteria present in the soil to precipitate calcium carbonate, resulting in improvements in the physical, chemical, mineralogical and mechanical properties of the soil, which allowed the mitigation of the erosion processes that characterize the soil profile studied.
