Ação de rodas compactadoras de semeadoras sob cargas verticais na deformação do solo em dois teores de água.

Abstract

The present work was lead in the assays track of sowing at (LAMMA) in UNESP/Jaboticabal, in São Paulo state, where was studied the action of press wheel under loads in the soil deformation by two moisture contents. The experiment was developed in block by change kind, with two moisture contents, and 6 loads, totalizing 12 treatments with three repetitions. Had been analyzed pressure and the soil deformation, proportionate for a aluminum press wheel, with 6.4 kg, 40 cm of diameter and 10 cm of width. The vertical loads had been gotten connecting on the press wheel lead ballasts. The soil moisture presented influence in the soil deformation and the increase of vertical loads on the press wheel was directly proportional the soil deformation.
