Abstract: Bananas are important tropical fruits conventionally cultivated under intensive nitrogen fertilization. A current challenge is to understand the environmental impacts of this crop across the different cultivation stages considering greenhouse gas emissions. Therefore, the present study evaluated whether inorganic fertilization with ammonium sulphate and urea during different planting stages can change soil CO2, CH4 and N2O emissions. The experiment was conducted in 2018 in an Atlantic Forest region of S?o Paulo State, Brazil. We used the chamber-based methodology for gas sampling in young and established banana plantations and in a forest remnant fragment. Seasonal differences in temperature and rainfall during the sampling period resulted in a larger WFPS during the wet season. The CO2 emissions followed the rainfall variations. CH4 fluxes were mainly resulted of methanotrophy reactions. The maximum and minimum N2O fluxes were 7.38 and ?0.93?mg?m2 day?1, peaking after nitrogen fertilization. We found that the accumulated N2O fluxes from soil were greater for the two banana plantations than those observed in the forest remnant in dry and wet seasons. The highest N2O peaks were observed in the young banana plantation. CH4 uptake was 92 and 61% less in young and established banana plantations than in the forest remnant, while N2O emissions were 95 and 74% greater in young and established banana plantations than in the forest remnant. Considering the negative effect of N2O emissions, reduced rates of nitrogen application and the adoption of conservation practices should be considered in young banana plantations.

Foram estudadas as características do "Malt Sauce", produto importado e empregado como matéria-prima pela indústria brasileira de uísque, focalizando-se principalmente os valores dos componentes secundários, suas variações e interrelações. Os resultados encontrados, baseados, em análises efetuadas na Seção de Análises Comerciais do Instituto de Tecnologia de Bebidas, ex-Instituto de Fermentação, no período de 1954 a 1967, demonstraram que o grau alcoólico real ficou situado na faixa de valores entre 57,5 e 62,30GL; a soma dos componentes secundários, entre 2,9 e 4,6 g~1,, no álcool a 100'GL e, dentro da soma: álcoois superiores 65,2%, ésteres 16,7%, ácidos totais 12,8% e aldeídos 5,3%. |
