Saturação por bases na integração lavoura-pecuária com cultivo de milho nos dois primeiros anos

Abstract: A maioria das pastagens no Cerrado encontra-se com algum grau de degradação. A estratégia de introduzir a cultura do milho em consórcio com capim na recuperação das pastagens é uma alternativa viável. Mas como os solos do Cerrado são ácidos, para que essa técnica seja viável, dentre tantos outros fatores, um dos principais é conhecer qual o nível de saturação por bases para o milho em consórcio. Assim, o presente estudo objetivou avaliar o efeito de níveis de saturação por bases sobre o crescimento e a produçã… Show more

“…One of them is the presence of basic cations in biochar, which increased the soil base saturation (after incubation) to 87% with the application of the highest rate (10.12 t ha -1 ). It is noteworthy that the increase in base saturation was mainly due to the contribution of K and Na and that the recommended base saturation for the maize monoculture is 65% (Brito, Pereira, & Brachtvogel, 2019). The increase in soil fertility with applications of biochar amounts larger than 6.6 t ha -1 likely caused imbalance and damage to the plant metabolism, interfering with the biochemical processes that occur in it.…”
