ABSTRACT
The soils of Brazilian Cerrado are characterized with high acidity and
low fertility and productivity. However, these attributes are not homogeneously
distributed through all phytophysiognomies of this biome, and wetland known as
palm swamp or “veredas” are an exception. This
study aimed to describe and
compare the chemical and physical attributes of soil surface layers at six palm
swamps areas under different anthropization processes in the northern region of
Minas Gerais state, Brazil. Soil sampling of different hydromorphic soils were
collected at 0-20 cm depth layer from 100 m2 plots in the studied
areas. The variables were compared using the GLM procedure of
ANOVA using Statistica 10 software. Soil chemical
attributes and similarities between the six palm swamps areas were compared using
the statistical software R. Soil chemical attributes were different and soil
physical attributes were similar between the evaluated areas. The similarities
among the attributes were classified into three groups according to the
anthropic pressures, as well as with the origin of the soil material in the six
palm swamps areas evaluated. It could be concluded that soil fertility
can be reduced in palm swamps that suffered greater anthropic intervention. The
three similarity groups might be associated not only to the anthropic
pressures, but also to the raw material of soil at the six palm swamps areas
evaluated.
