Resumen
Descripción
This paper is comprised of five parts. The first part discusses the role of legumes in sustainable soil management and crop-livestock production. In this part, strategic use of legumes, selection of forage legumes to sub-optimal soil conditions, use of appropriate rhizobium, response of legumes to phosphorus and evaluation of rockphosphates, and correction of other nutrient deficiencies are examined. The second paper deals with the role of crop residues and animal manures with particular reference to crop residues for feed or soil conservation, and effects of animal manure on long-term soil management. Measuring the sustainability of improved crop-livestock systems is the topic of part four. This part discusses the concept of intertemporal and interspatial TFP measures and indices of intertemporal and interspatial TFP. The last part of the paper presents and discusses research priorities.
