EVALUATION OF CATION AND ANION LEACHING IN A SOIL AFTER TREATMENT WITH ALPERUJO

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 Ca²⁺+Mg²⁺, 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⁺>Ca²⁺+Mg²⁺. 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.
