Conteúdo: |
Study on oil and plant N dynamics as affected by fertilization and intercropping with a legume, in the central Amazon (Brasil). Soil samples up to 4 m depth were taken under guarana and in the middle between the trees at the end of the rainy and the end of the dry season. The results indicate large risks of nitrate leaching and a lack of available N at the end of the rainy season. The tree was able to use N from the subsoil and between the trees. However, without adequate fertilization with other nutrients than N and also with a cover crop, the N availability was higher than the demand by the tree. This lead to N leaching. Therefore, N fertilization could be reduced to more efficiently utilize the soil inherent N sources and the N supplied by the legume cover crop. |
