Soil attributes in Brazilian palm swamps ecosystems in the Cerrado of Minas Gerais state
The aim of this study was to characterize the soils of veredas (Brazilian palm swamps) ecosystems and their surrounding savannas, in different stages of degradation. Three veredas ( Água Doce, Capivara and Buriti Grosso) and their respective surrounding cerrados (savannas) were selected. Soil sampling was performed in the layers 0-10, 10-20, 20-30, 30-40, 40-50, 50-75 and 75-100 cm to assess chemical attributes, granulometry, bulk density and stocks of soil nutrients. The data were subjected to analysis of variance and compared by Tukey test (p < 0.05). The soils in both environments were classified as sandy presenting high apparent density (1.40 to 1.65 g cm-3). The pH in the preserved vereda was higher in relation to the anthropized areas. In both areas the pH was acidic, with very low sum of bases, Al and potential cation exchange capacity (CTC). Nutrient stocks were similar between areas and higher in savanna environments. Potassium showed the greatest variation, with higher values in areas with degradation. We concluded that anthropic interventions in the studied environments influenced soil attributes.
