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...

Low nutrient availability, especially phosphorus (P) and nitrogen (N) supply is the major limitation to forage production in acid infertile soils of the tropics. A field study was conducted at the farm ‘La Es- peranza’ located in Mondomo, Department of Cauca, in the coffee growing zone of Colombia...

Low phosphorus (P) supply is a major limitation to pasture establishment and production in highly weathered acid soils. Previous research showed that the forage legume, Arachis pintoi, was more efficient in acquiring P from infertile acid soils than the forage grass, Brachiaria dictyoneura. The m...

desacelerar la decadencia de la pastura; y el sistema de enraizamiento profundo y abundante de las gramíneas recibe el C atmosférico fijado y lo secuestra luego en profundidad en mucha mayor cantidad que las especies de la sabana nativa. Dada la gran extensión que ocupan las pasturas de Brachiari...

In many low input agricultural systems, phosphorus (P) is one of the most limiting mineral nutrients for plant production. Although applying P fertilizer, if available, is the most performing practice, this should be accompanied by other measures. The use of genetically enhanced plants with impro...
