Conteúdo:  Water availability is predicted to be reduced and temperature to rise in the global climate change context. Future climate conditions may thus represent a serious risk for coffee cultivation especially in less favorable environment. Agroforestry has been postulated as a promising strategy to adapting to climate changes. Shade tree may minimize radiation and temperature near the soil surface and reduce soil evaporation. Shade tree may enhance infiltration, reduce runoff and increase rainfall water use efficiency by taking up water from deep soil layers. However, shade tree may reduce the water that reaches the soil by rainfall interception. Trees may consume additional water and can establish a competitive relationship depending on tree species characteristics, soil water availability, site conditions and management. In this experiment water dynamics and use was monitored in a mature agroforestry experiment where coffee shaded by a mixture of Tabebuia rosea and Simarouba glauca is compared to full sun coffee over 2012 and 2013. The water balance was obtained by two independent approaches: 1) measuring directly all components of water balance (trees and coffee transpiration; soil evaporation; rainfall interception); and 2) measuring changes in the soil water stock through Time Domain Reflectometers (TDR) probes. Agroforestry (AFS) showed greater transpiration and lower soil surface evaporation compared to full sun (FS). Shade tree did not repr... Mostrar Tudo
