Resumo
Quirinópolis Micro region depicts great expansion of sugar cane production on the clayed Red Latossols but due to
the increasing demand of new areas the naturally less fertile, the dystrophic Red Latosol of medium texture was
done. Such soils are considered weak to the extent of structural stability and impact installation such erosion and
compression, this one primarily due to highly high technified management, as though the sugar cane, which heavy
machinery during all stages of culture. The aim of this study was to evaluate the physical quality of LVd with current
use of sugar cane, however previously varied successions (soybeans, pasture and grazing succession/soybean),
with reference to soil profiles of areas with remaniant vegetation. Thus, we obtained macro and micromorphologic
indicators, physical and penetration resistance. The results revealed changes in micro and macrostructure,
consistency, clay dispersion, soil bulk density and penetration resistance on cultivated soil profiles compares with
natural cover profile, indicators compatible of degradation by compaction, however moderate.
