摘要

The leach of soluble inorganic ions and exchangeable cations in a Petrocalcic Paleudolls soil was studied. Doses of alperujo, between 0 and 80 t/ha, were applied at Ap horizon and 669 mm of deionized water were poured onto the soil. Leachates showed predominance of Ca~(2+)+Mg~(2+), Na~+ and HCO3"; its pH increased until about eight; and the electrical conductivity reached values between 0.42 and 0.63 dS/m. Cations at the exchangeable complex of Ap horizon decreased according to the trend Na~+>K~+>Ca~(2+)+Mg~(2+). The remaining horizons showed enrichment of K~+ when alperujo increases. At the amounts evaluated, the application of alperujo did not have adverse effects on the soil.
