Influence from Eutrophication of Soil in the Brazilian Savanna Vegetation

Abstract

The aim of the work was to demonstrate if exists a relation between eutrophic processes of soil (N, P, K, pH, and organic matter) with phytosociology mosaic of native tree species in Brazilian adjacent sanitary landfill areas of the savanna. In recent decades, eutrophication has become a significant global problem. About the studies areas, one of them is located in the city of Brasilia (Federal District) and the other one in the main city Goiânia of the state Goiás, 120 km away between both cities. The used methodology was some techniques and an electronically package to this purpose. For the purpose of conducting a vegetation and soil survey, plots and subplots were used for each region. A correlation between eutrophic processes of soil and the phytosociological mosaic of indigenous savanna tree species was demonstrated statistically.
