Resumo
The expansion of the culture of sugar cane in Brazil is being driven towrds the
Brazilian Midwest, particularly in the states of Mato Grosso do Sul (MS) and Goiás,
since the end of last century. Goiás stands out in this process, but is now among the
three states with the largest cultivated area and production. South mesoregion excels,
especially micro-Quirinopolis (MRQ), where the process began in 2004, replacing grain
areas and pastures. This research aims to analyze the influence of different management
practice in the cultivation of cane sugar in the MRQ, using sensitive biological and
physico-chemical indicators of water quality and soil, to contribute to sustainable
models with parameters that sugarcane expansion. Eight sampling sites were selected in
areas occupied by soil type Red Oxisol dystrophyc and distroferric, with previous uses
of soybeans, pasture and pasture / soybean, and in parallel, two profiles as a reference,
with native vegetation, the type Semidecidual Forest, once dominant. Were also selected
two stocks next crop of sugar cane, collections with the Montate and downstream of
each channel. Descriptions and Samples of soil and water were carried out in September
2010 and March 2011. Proceeded physical, chemical and biological analysis of soil and
water by applying methods of Pedology, Biology and Ecology. It was concluded that
different agricultural practices directly influence the dynamics of soil and water,
unbalancing the biota, due to change in their physico-chemical and biological attributes
that succession soy / sugar use biomarkers showed. The same applies to the water, but
these can not yet be regarded as polluted by CONAMA parameters.
