Nitrogen is the most limiting nutrient in many agricultural ecosystems. The integration of legumes (herbaceous and trees species) can contribute to: 1) minimize external inputs, particularly nitrogen fertilizers, in agricultural ecosystems; 2) increase resource and land use efficiency in cattle production systems; and 3) mitigate global warming. In the introduction, this paper presents a review of the ongoing and projected global trends in beef and milk production and consumption, with particular focus in the developing countries, most of which are located in the tropics.</style></abstract></record></records></xml>
