Introducción. El óxido nitroso es un gas de efecto invernadero gran impacto sobre el calentamiento global. En los sistemas producción ganaderos importancia buscar alternativas que permitan mitigar las emisiones N2O, dentro cuales se ha considerado uso coberturas vegetales capaces reducir proceso nitrificación. Objetivo. Evaluar la dinámica flujos N2O en suelos bajo ocupación ganadera cubiertos ...

Protodioscin is used as a marker of saponin content that could cause hepatotoxicity in ruminants. In Brachiaria spp. from two regions of the Colombian Eastern Plains (east mountain range of the Andean-"piedemonte" and Ariari River Valley) were determined this metabolite at 14 and 28 days post-cutting under different climatic conditions. No protodioscin was detected in B. dictyoneura or B. humid...

Phosphorus (P) deficiency and aluminium (Al) toxicity are widespread in Oxisols of the tropical savannas of eastern Colombia. A field experiment was conducted to determine the effect of Al toxicity and P deficiency on plant growth and nutrient uptake of two Brachiaria species. To examine the influence of nutrient supply and lime on root and shoot growth, two levels of fertiliser application (lo...
