Journal ArticleDOI
Recycling of water in the Amazon Basin: An isotopic study
TL;DR: The oxygen-18 content of precipitation in the Amazon basin is characterized by a very small inland gradient, 0.75 × 10−3 ‰ km−1 as discussed by the authors, which is a consequence of the large contribution of reevaporated moisture to the basin's water balance.
Journal ArticleDOI
Confirmation of nitrogen fixation in two tropical grasses by 15N2 incorporation
TL;DR: The addition of sucrose to the soil doubled N2-fixation in roots in both grass species studied, but did not result in increased incorporation into the leaves of P. notatum.
Journal ArticleDOI
The use of the 15N isotope dilution technique to estimate the contribution of associated biological nitrogen fixation to the nitrogen nutrition of Paspalum notatum cv. batatais
TL;DR: This paper reports the results of a field experiment to investigate the use of the 15N-dilution technique to measure the contribution of biological N2 fixation to the N nutrition of the batatais cultivar of Paspalum notatum.
Journal ArticleDOI
The 15N-isotope dilution technique applied to the estimation of biological nitrogen fixation associated with Paspalum notatum cv. Batatais in the field.
TL;DR: The total N and 15 N data of these two grasses were not in good agreement indicating that it is important for the use of the isotope dilution technique that control plants are of very similar physiology and growth habit.
Journal ArticleDOI
Estudo da interceptação da água de chuva em cobertura florestal amazônica do tipo terra firme
TL;DR: In this article, the fraction of the rainfall intercepted by a canopy forest, located at the Reserva Florestal Ducke, 26 km far from Manaus, was determined, and the results showed an average rainfall interception of 19,8%.
