1. Parametros de manejo de irrigacao e adubacao nitrogenada para o cultivo de cevada cervejeira no cerrado.
Este trabalho foi desenvolvido na area experimental do Centro de Pesquisa Agropecuaria dos Cerrados (CPAC) com o objetivo de determinar os parametros de manejo da agua de irrigacao e a dose de nitrogenio em cevada visando a maximizar a producao de graos com qualidade para malteacao. Foram testados os quatros niveis de tensao de agua no solo de 52, 162,526 e

2. Hydrological regionalization of flows and loads of total suspend solids for the program Producers of Water and the payment of environmental services. Case study of river basin Benevente, ES / Regionalização hidrológica de vazões e de cargas difusas de sólidos suspensos totais para o programa ProdutorES de Água e o pagamento de serviços ambientais. Estudo de caso: bacia hidrográfica do rio Benevente, ES
Systems of payment for environmental services of a catchment area can be economically attractive and ecologically important. Programs such as Producers of Water economically compensate owners upstream of the basin using the proper management of land use, and reforestation to prevent erosion, increased pollution loads diffuse and increase the availability and

3. Dinâmica biogeoquímica do estuário do Rio Itajaí-Açú, SC.
The Itajaí river estuary, SC, is located in the final portion of Itajaí river watershed, which has a total area of about 15,500 km2. The terminal region of this watershed is characterized by the presence of important cities such as Blumenau and Itajaí. Agriculture is also important, specially irrigated rice culture. The aim of this study was to evaluate t

4. ÁGUA NO SOLO E RENDIMENTO DE TRIGO, MILHO E SOJA, ASSOCIADOS AO FENÔMENO EL NIÑO OSCILAÇÃO SUL E À MUDANÇA CLIMÁTICA SIMULADOS PARA SANTA MARIA, RS. / SOIL WATER AND WHEAT, MAIZE AND SOYBEAN YIELD AND ITS ASSOCIATION WITH THE EL NIÑO SOUTHERN OSCILATION AND CLIMATE CHANGE, SIMULATED FOR SANTA MARIA, RS.
O El Niño Oscilação Sul (ENOS) é um fenômeno de grande escala que afeta o tempo e o clima em diversos locais do Globo Terrestre, incluindo o Brasil, especialmente as regiões Sul e Nordeste brasileiro. A água disponível no solo para os cultivos é um importante fator de variabilidade interanual da produção agrícola no Estado do Rio Grande do Sul. O

5. Avaliação de modelos matemáticos desenvolvidos para auxiliar a tomada de decisão em sistemas de produção de ruminantes em pastagens. / Evaluation of mathematical models developed to aid decision-making in pasture-based ruminant production systems.
In agricultural systems, environment, soil, animals and plants are indissociable components of the production process. Furthermore, the production time-frame is relatively long. These characteristics enhance risk and uncertainty associated with decision alternatives made during the process. One tool which can aid in decision-making in these processes is the

6. A global budget for fine root biomass, surface area, and nutrient contents
Global biogeochemical models have improved dramatically in the last decade in their representation of the biosphere. Although leaf area data are an important input to such models and are readily available globally, global root distributions for modeling water and nutrient uptake and carbon cycling have not been available. This analysis provides global distri
