Descripción:	The objectives of this study are 1) to develop cropping sequences using legume green manures which keep losses of Ca, Mg, K, and N03 to economically and environmentally sound levels, and 2) to develop models that describe the losses of Ca, Mg, K, and N03 under different soil and climatic regimes and to define the input data required for these models.
