Abstract

This work presents the results of three experiments carried out in "cerrado" soil in order to check out the effects of liming on the contents of calcium plus magnesium of those soils. After the experimental period (5 years) soil samples were taken from depths of 0-10, 10-20, 20-40, 40-70 and 70-100 cm and the amounts of exchangeable calcium plus magnesium were determined. It was observed that the contents of the exchangeable cations mentioned above increase with the amount of 1ime applied. It was verified a pronounced penetration of calciumplus magnesium in the profiles of the soils, and this was more evident in the most sandy ones.
