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
