Los sistemas ganaderos de doble propósito representan el 78% del inventario ganadero en América Latina tropical y contribuyen con aproximadamente el 42% de la leche producida. Sin embargo, se caracterizan por baja productividad animal debido a sistemas deficientes de alimentación basados básicame...

Bean ( Phaseolus vulgaris check for this species in other resources L.) production in Africa is constrained by edaphic stresses. A pan-African effort, Bean Improvement for Low Fertility in Africa (BILFA), was initiated in 1990 to screen beans for tolerance to several edaphic stresses. In the fir...

Tropical soils are particularly vulnerable to fertility losses due to their low capacity to retain organic matter and mineral nutrients. This urges the development of new agricultural practices to manage mineral nutrients and organic matter in a more sustainable way while relying less on fertiliz...
