Behavior of the resistance to the penetration in a chromic vertisol planted with sugarcane.

Abstract

For study the influence of the sugarcane on the resistance from the soil to the penetration in a Chromic Vertisol, they were evaluated the stumps cane plant and 1^st sprout. They were settled down 24 observation points being carried out, with an impact penetrometer, the samplings in the furrow and in the ridge, to the depths 0-10, 10-20 and 20-30 cm. An analysis of variance took effect and the test of multiple status of Duncan was used to 95 % of probability. Cane plant was found that, in the furrow, the first 10 cm are few compacted upon on a fairly compacted layer that arrives until the 30 cm; while in the ridge the thickness of the superficial layer few little compacted is much bigger. In 1^st sprout, as much in the furrow as in the ridge, the soil is fairly compacted until the 30 cm.
