ABSTRACT The present study aimed to evaluate water quality attributes in micro-watersheds under different soil uses. Therefore, four micro-watersheds under the following vegetation cover were selected: pasture, primary forest reforestation, forest, and coffee plantation. Surface and underground water sampling was performed bimonthly between February and December 2014, where thermotolerant coliforms, dissolved oxygen, total nitrogen, phosphorus, turbidity, temperature, pH, biochemical demand for oxygen and total solids were analyzed. Descriptive analyses of each variable were performed during dry and rainy periods, and the values were compared with the normative standards established by Brazilian legislation. Water Quality Indices (WQIs) were also calculated for each collection site. All sites presented some type of nonconformity with human consumption standards. The highest WQI values were found in the forest area micro-basin, followed by the coffee plantation and pasture area micro-basins, highlighting the importance of forested areas for water quality.

RESUMOOs produtos do açaí (Euterpe oleracea Mart.) apresentam grande importância econômica e cultural no Brasil com um crescente mercado consumidor. Com intuito de fornecer bases para ampliação desse cultivo em outros estados, buscou-se elaborar o zoneamento agroclimático para essa cultura no estado do Espírito Santo. Para tanto, utilizou-se de dados meteorológicos de 110 estações de órgãos governamentais e da ferramenta geotecnológica ArcGIS 10.1 para espacializar os dados de temperatura, precipitação e déficit hídrico e depois reclassificá-las para a geração do zoneamento. Os resultados demonstraram que 20,74% da área total do Espírito Santo possui zonas aptas a essa cultura, localizadas nas regiões Nordeste, Serrana e Sul, sendo Linhares o município com maior aptidão. Embora a maior parte do estado tenha algum tipo de restrição que limita o cultivo, seja da variável déficit hídrico, seja da precipitação, algumas técnicas podem minimizar tais restrições. Logo, torna-se viável a implantação da cultura do açaí no estado do Espírito Santo de acordo com as variáveis temperatura, precipitação e déficit hídrico.

ABSTRACTThe products of acaí (Euterpe oleracea Mart.) have great economic and cultural importance in Brazil with a growing consumer market. Seeking to provide a basis for the expansion of this crop in other states, we sought to develop the agroclimatic zoning for this crop in the state of Espírito Santo. Therefore, we used data from 110 meteorological stations and governmental geotecnologic's tool ArcGIS 10.1 for spatialize temperature data, precipitation and water deficit and then reschedule them for the generation of zoning. The results showed that 20.74% of the total area of the Espírito Santo has areas suitable to this culture, located in the Northeastern, Southern and mountainous, with Linhares the municipality with the highest fitness. Although most of the state has some kind of constraint that limits the cultivation, whether the variable is water deficit precipitation, some techniques can minimize such restrictions. Thus, it becomes feasible to implement the culture of acai in the state of Espírito Santo according to the variables temperature, precipitation and water deficit.
