Alumínio trocável e saturação em bases como critérios para recomendação de calagem

Abstract: O critério do alumínio para determinar a necessidade de calagem de solos, vem sendo usado há dezesseis anos no Brasil. As quantidades de calcário indicadas são em geral baixas. Neste trabalho, procurou-se avaliar esse método, com base em resultados de ensaios de calagem, realizados em três locais e durante vários anos. Em Mococa, em podzólico vermelho-amarelo, foram considerados cinco plantios de milho, um de algodão e um de soja; em São Simão, em latossolo vermelho-escuro textura média, três plantios de soja;… Show more

“…As consequence of lime application, there is also in increase in pH to levels estimated by formulas such as those of Catani and Gallo (1955) and Raij et al (1983), which characterize the correlation between base saturation and pH. In this method, the actual base saturation of the soil and the desired saturation are considered, as well as the CEC at pH 7 (T) .…”
