Directions in tropical agroforestry research: past, present, and future, the high expectations that were raised about the role and potential of agroforestry as a development vehicle have not been fulfilled. In order to overcome this, it is imperative that research be focused on the generation of appropriate, science-based technologies of wide applicability, especially u

Of the available techniques for assessing N.-fixation by trees, the total N difference method (TND) is the simplest. The contribution of roots to ass

Priority areas for future research include theoretical and empirical analyses of agroforestry adoption decisions, improved economic analyses, and policy studies at local, national, and regional levels.
