Abstract: Resumo€Œ€O objetivo deste trabalho foi quantificar as perdas de N do sistema solo-cana-de-acœcar, nosciclos de cana-planta e de cana-soca. Desenvolveram-se dois experimentos em vasos de 220 L, conten-do solo de classe textural arenosa. Os€fatores de estudo do experimento com cana-planta foram doistipos de restos culturais incorporados ao solo e quatro doses de N no plantio. No€experimento comcana-soca, estudaram-se duas formas de aplicacao da urOia em superficie: sobre a palha ou sobre o solodescoberto, ou na profundidade de 15€cm, e duas fontes de K: KCl ou vinhaca. Utilizou-se urOia marcadacom

TL;DR: Optimizing the need for a key human resource while minimizing its negative consequences requires an integrated interdisciplinary approach and the development of strategies to decrease nitrogen-containing waste.
Ammonia volatilization losses from surface-applied urea with urease and nitrification inhibitors
TL;DR: In this article, the effects of treating urea with both urease inhibitor and nitrification inhibitor to minimize NH3 volatilization were investigated in a controlled environment, where two experiments were set up to examine this process.

Reassessing the environmental impacts of sugarcane ethanol production in Brazil to help meet sustainability goals.
Solange Filoso,Janaina Braga do Carmo,Silvia Fernanda Mardegan,Silvia Rafaela Machado Lins,Taciana F. Gomes,Luiz Antonio Martinelli +5 more
TL;DR: The potential for sugarcane ethanol from Brazil to mitigate GHG emissions is undeniable, but the way that ethanol is produced during the agricultural and industrial phases will ultimately determine its benefits to society.

Leaching of nutrients from a sugarcane crop growing on an Ultisol in Brazil.
P.J. Ghiberto,P.J. Ghiberto,Paulo Leonel Libardi,A.S. Brito,Paulo Cesar Ocheuze Trivelin,Paulo Cesar Ocheuze Trivelin +5 more
TL;DR: In this paper, the loss of nitrogen and sulfur by leaching, at the depth of 0.9m, in an Ultisol in Sao Paulo State (Brazil) with high permeability, was quantified from the flux density of water and the concentration of the elements in the soil solution at this soil depth: tensiometers, soil water retention curve and soil solution extractors were used for quantification.

Nitrous oxide emissions from intensive agricultural systems: Variations between crops and seasons, key driving variables, and mean emission factors
TL;DR: In this article, emissions of nitrous oxide from intensively managed agricultural fields were measured over three years and the relationship with the driving variables showed strong similarities to those reported for very different environments: irrigated sugar cane crops, pastures, and forest in the tropics.

On the Gaseous Exchange of Ammonia between Leaves and the Environment: Determination of the Ammonia Compensation Point
TL;DR: The compensation points in several species are near the low partial pressures found in unpolluted air and approximate to the K(m) of glutamine synthetase in vitro, and in P. vulgaris L., the compensation point increases with temperature, termed the ammonia compensation point.
