Abstract

The objective of this study was objectified to evaluate the resistance to the penetration of the soil in area as seven successions of cultures, involving the double cropping cultures: corn, soybean, pearl millet, sunflower, sorghum, oat and turnip fodder, with the culture of the soybean, in no-tillage, driven for three years (1994-1996), in the Foundation experimental area of Higher education de Rio Verde, in the municipal district of Rio Verde, Goiás. In the last year, in the between cultures of double cropping it measured the resistance to the penetration in the soil in different layers between 0 and 30 depth cm, using penetrographer. Significant interaction was observed between successions of cultures and depths in the profile of the soils for the appraised characteristic. The successions that include pearl millet and sorghum reduce the penetration of the soil to 15 cm of depth bought to the sunflower. In this depth the soil offered tendency the largest resistance to the penetration in all the appraised treatments.
