Economic and environmental viability of substituting lupins for soybeans: The case of dairy farming in Southwest Quebec

The research investigates the potential fur the inclusion of lupins (Lupinu s spp.) in the crop mix of a typical dairy farmer in Southwestern Quebec. T his crop is an alternative legume crop to soybean but it contributes to a g reater reduction in soil loss and more nitrogen being fixed for future crop s than soybean. Results of a linear programming approach to the problem ind icate that the crop can be profitably included in the crop mix with environ mental benefits. (C) 2001 by The Haworth Press, Inc.
