CALCÁRIO LÍQUIDO E CALCÁRIO CONVENCIONAL NA CORREÇÃO DA ACIDEZ DO SOLO

Abstract

A acidez pode alterar a disponibilidade dos nutrientes no solo. Objetivou-se com o presente trabalho avaliar o efeito da aplicação de calcário líquido e calcário convencional na correção da acidez de um Latossolo Vermelho-Amarelo distrófico do Cerrado. O delineamento experimental utilizado foi inteiramente casualizado, com três repetições. As doses de calcário líquido aplicadas foram equivalentes a 5; 10; 15 e 20 L ha-1 e as doses de calcário convencional utilizadas foram equivalentes a 1,0; 1,5; 2,0 e 2,5 t ha-1. Após a aplicação dos corretivos de acidez, o solo foi acondicionado em recipientes com capacidade para 0,4 dm3 com umidade próxima a capacidade de campo. Aos 70 dias após a aplicação dos corretivos foram mensurados o pH do solo, teores de potássio (K+), cálcio (Ca2+), magnésio (Mg2+), alumínio trocável (Al3+), acidez potencial (H+Al) e calcularam-se a capacidade de troca de cátions (CTC), saturação de bases (V%) e saturação de alumínio (m%). O calcário líquido não corrigiu a acidez do solo e não elevou a saturação por bases, apenas elevou os teores de Ca no solo. A aplicação de doses de calcário convencional proporcionou correção da acidez do solo e elevação da saturação de bases.
