Greenhouse gases emission during vinasse and trash in areas cultivated with sugar cane: analytical infrastructure expansion


Brazil is the largest producer of cane sugar and current perspectives are of great growth in the sector, taking into account, among other factors, the interest of many countries to use ethanol as fuel, in the context of the protocol Kyoto and environmental and geopolitical issues surrounding fossil fuels. However, ethanol production has received considerable criticism, especially in the scenario of climate change and global warming. However, such criticisms were not based on direct measurements of N2O emissions in sugarcane and so little in intensive assessments covering the major soil management of the production cycle (vegetative) plant. Therefore, the sector requires that such measures are made, and nothing is known about the use of waste in the soil for the cultivation of sugar cane in Brazil, with respect to emissions of gases that cause greenhouse gas (GHG) Therefore, the main objective of this proposal is to expand the scientific infrastructure of the Bioclimate Laboratory from UFSCar campus Sorocaba (SP) to increase the efficiency of analytical samples, may meet the demands of research partners in the area thereby increasing and improving knowledge of the country on losses of N as N2O and other greenhouse gases during the production cycle of cane sugar after the application of two types of vinasse (regular and concentrated vinasse). Besides these measures, evaluations of leachable nitrogen forms and edaphic parameters after fertilization and vinasse, will also be focus of this project. (AU)
