Testing the safety-net role of hedgerow tree roots by 15N placement at different soil depths,ittle .N from any depth but obtained an estimated 44–58% of its N from atmospheric N.-fixation. . took up an estimated 21 kg N ha. and Peltophorum an estimated 42 kg N ha. from beneath the main crop rooting zone. The results demonstrate that direct placement of .N can be used to identify N sourcing

Temperature and water-use efficiency by lucerne (,) sheltered by a tree windbreak in Tunisia,ed a decrease in above ground biomass production and water use efficiency when a highly restrictive water regime was applied. In July, daytime temperatures were disadvantageous to the lucerne, and even with a high degree of water availability, there were no significant differences between sheltered

Competition for light, water and nitrogen in an association of hazel (, L.) and cocksfoot (, L.),rriers were needed to exclude it. The second plantation was managed on a deep soil with a water table at approximately 2.5 m depth. The trees did not suffer from the presence of grass, and allowed a 15 to 75% light transmission rate. A control monocropped grass plot was established for comparison. O

,Simulating integration of agroforestry into livestock farmers’ projects in France,nes (southern France). The outputs of the model, related to labour requirements, stock number dynamics and landscape diversity are discussed in relation to farmer’s perception of the role of trees in the farm operation, and the indirect economic benefits sought.
