riesgo de compactación del subsuelo. La resistencia a la penetración resultó un buen indicador para evaluar efectos físicos sobre el suelo causarlos por implementos de labranza y él tránsito de maquinaria.
the maximun soilloosening. However those treatments were the most sensitive to compaction due to the traffic of tractor
wheels. This work did not present conclusive evidence that bottom of furrow made by disk plough is a place of high risk for subsoil cornpactlon. Cone penetration resistance looks like a good index to assess changes in physical properties of the soil caused by tillage operations and machinery traffic.
