Volatilização de N-NH3 de fontes nitrogenadas em cana-de-açúcar colhida sem despalha a fogo [PDF]

Revista Brasileira de Ciência do Solo, 2003
Com a colheita da cana sem queima, espessa camada de palha é depositada sobre o solo. A presença da palha modifica o agroecossistema, exigindo reformulação na tecnologia de manejo da cultura. Na adubação nitrogenada da cana-de-açúcar, a uréia é a fonte de N mais utilizada e, quando aplicada sobre a palha, apresenta elevadas taxas de perda de N-NH3 por ...
