Red-Yellow Latosol Penetration Resistance Under Different Subsoiling Depths

ABSTRACT The objective of this work was to evaluate the penetration resistance (PR) of a red-yellow latosol submitted to two subsoiling depths for implanting a forest plantation. The subsoiling was evaluated at 40 cm (S-40) and 50 cm (S-50) of depth by determining the soil moisture and soil density, while soil PR was evaluated before and after subsoiling at five points transversely to the subsoiling line (furrow) up to a depth of 60 cm using an electronic penetrometer. The soil density in both treatments was not altered by soil management. Before soil preparation, the soil presented PR values ...
