Résumé:
The work objectified to evaluate alterations in the physical characteristics in a Typic
Haplocambids, cultivated with melon, in function of the culture time. The election of the areas was
made taking in consideration four times of use, being an area of virgin bush and areas with one, two and
three years of culture. In each area, the collection of the soil samples was carried through in 3 points, in
2 depths (0-20 and 20-40 cm). Had been determined texture, particles density, bulk density, porosity
and aggregate stability. The data had been submitted to the variance analysis, considering a factorial 4 x
2 (4 times of use and 2 depths), with 3 repetitions. The results had demonstrated that in function of the
time, the culture practical had significantly improved the bulk density and provoked reduction of the
average size of steady aggregates in water.
