Most commercial Brachiaria species are adapted to low-fertility acid soils of the tropics. We describe, with examples, some of the attributes that enable them to adapt. These include the ability to (1) maintain root growth at the expense of shoot growth; (2) acquire and use both nitrate and ammon...

Cassava is drought-tolerant and grows reasonably well in relatively infertile soils where other crops would fail. However, production could be further increased if important soil-related constraints are addressed. In order to supply cassava plants with the nutrients required for optimal productio...

Efforts to develop cassava technology for the vast areas of acid infertile soils were continued Large-scale germplasm screening in the field was begun in Carimagua for tolerance to low levels of P and acidity and in Quilichao, for tolerance to low levels of P. Various fertilizer trials were used ...

Se continuaron los esfuerzos para desarrollar tecnologia de yuca adecuada para las vastas extensiones de suelos acidos e infertiles; en Carimagua se inicio la seleccion de germoplasma en gran escala a nivel de campo para buscar tolerancia a bajos niveles de P y a la acidez y en Quilichao toleranc...
