40. Estudo comparativo da aplicaÃÃo de vinhaÃa tratada e in natura em solos sob cultivo de cana-de-aÃÃcar
Brazil is the world leader in sugarcane plantation. Its economical exploration generates residues, standing out the vinasse. Due to the problems of ecological and social order caused by the vinasse, the most plausible solution for its disposition is the application to the soil as fertilizer. However, that application requests studies to guide the management

41. Environmental impacts and nutrient recycling on pastures grazed by cattle
Grasslands are being replaced by urbanization and more profitable agricultural activities around the world. Producers may be faced with land constraints and need to consider intensification of the remaining grasslands as a means of maintaining overall production on a decreasing land resource. However, intensification of the grazing system is usually associat

43. Contaminação de aqüífero por hidrocarbonetos: estudo de caso na Vila Tupi, Porto Velho - Rondônia
Underground storage tanks (UST) are widely used in the Porto Velho area. A large number of these USTs are in bad condition due to corrosion processes causing groundwater contamination. A large number of these leaking underground fuel tanks (LUFT) are in urban areas but due to the lack of water quality monitoring, they are only detected when there is a high c
