Evaluation of the Physical Attributes of Soil under Different Uses and Management in the Territory of the Zona da Mata in Rondônia, Brazil
Journal Title: International Journal of Advanced Engineering Research and Science - Year 2018, Vol 5, Issue 12
Abstract
The results of soil use is widely known mainly for the productivity and visual aspect of plant development. In order to characterize the results of the different soil management, this study was carried out on family farms in the Zona da Mata Territory in Rondônia. The samples were submitted to physical attributes analysis of density, total porosity, macroporosity, microporosity, aggregate stability and organic matter analysis. The soils under different uses were negatively influenced when compared to the forest, having in average decrease in total porosity, macroporosity, organic matter and increase in microporosity and density.
