Resumo: This study was based on two experiments carried out in Western Santa Catarina, Brazil, to evaluatethe effect of pig slurry and N fertilizer on soil nutrient availability in no-till corn on a Red Latosol (Oxisol). Soil samples were collected after the last corn cropping (season 2003/04), at dephts of zero to 5, 5 to 10 and 10 to 20cm, and were submited to chemical analyses. Treatments consisted of zero, 40 and 115m3/ha of pig slurry applicationon the soil, combinated with zero, 60 and 120kg/ha N. Surface application of pig slurry in no-tillage system increased the nutrient availability mainly at zero to 5cm depth. Utilization of pig slurry for three or four years increased the contents of organic matter, cation exchange capacity and extractable phosphorus. The intensity of observed alterations in the layers were proportional to the application rates. Treatments had no effect on the exchangeable K, Ca, Mg, Al and pH. It was observed that phosphorus in a clayey Latosol has very low mobility.

Este trabalho é baseado em dois experimentos de campo, conduzidos na Região Oeste de Santa Catarina, com utilização de esterco de suínos e adubo nitrogenado em milho no sistema plantio direto. Para o estudo foram coletadas amostras de solo nas profundidades de zero a 5, 5 a 10 e 10 a 20cm, com o objetivo de avaliar o efeito da adubação com esterco (zero, 40 e 115m3/ha) e nitrogênio (zero, 60 e 120kg/ha) nas características químicas do solo. A utilização de esterco de suínos em aplicação superficial, no sistema plantio direto, afeta as características do solo principalmente na camada de zero a 5cm. A sua utilização por um período de três a quatro anos na adubação do milho afetou os teores de matéria orgânica, CTC e fósforo disponível na camada superficialdo solo. As alterações observadas foram proporcionais à dose aplicada. Os teores de K, Ca, Mg e Al trocáveis e o pH não foram afetados pela aplicação de esterco e adubo nitrogenado. O fósforo teve pouca mobilidade e acumulou-se em maiores quantidades na camada de zero a 5cm.
