Resistência à penetração na soleira em solo preparado com diferentes tipos de arados.

Abstract

A study was realized on soil resistance to penetration at the threshold caused by four plow-types, respectively three moldboard plows (usual moldboard, special notched moldboard, and square plow), and one diskplow, in a Terra Roxa Estruturada soil, with 291.8g/kg moisture content. All four plows caused increased soil resistance at the threshold. However, whe comparing values among the four, no significant differences were observed between plows.
