Soil improvement by trees in sub-Saharan Africa, through (1) input of N by biological N. fixation, (2) retrieval of nutrients from below the rooting zone of crops and (3) reduction in nutrient losses from processes such as leaching and erosion. Trees can increase the availability of nutrients through increased release of nutrients from soil organ

Shade management in coffee and cacao plantations,so compete for growth resources. For example, shade trees buffer high and low temperature extremes by as much as 5 °C and can produce up to 14 Mg ha. yr. of litterfall and pruning residues, containing up to 340 kg N ha. yr.. However, N. fixation by leguminous shade trees grown at a density of 100 to

Directions in tropical agroforestry research: past, present, and future,d experiential approach but have subsequently followed a deductive and experimental approach that includes hypothesis testing and the development of predictive capability; agroforestry research is thus being transformed into a rigorous scientific activity. The research agenda, so far, has given high
