The Llanos region of Colombia represents one of the last large agricultural frontiers and is undergoing a rapid conversion from naturalized savanna to intensive agriculture with high agrochemical inputs and tillage. This massive land-use conversion has considerable impact on ecosystem services an...

This study was conducted to establish parameteres on the optimum spacing and level of nitrogen required for the establishment of most cultivated grass pastures including Brachiaria decumbens. It was found that 20x20 cm spacing of rooted sprigs of signal grass and either 100 or 200 kg N ha were si...

Soil carbon distribution with depth, stable carbon isotope ratios in soil organic matter and their changes as a consequence of the presence of legume were studied in three 12-year-old tropical pastures (grass alone Brachiaria decumbens (C4), legume alone Pueraria phaseoloides (C3) and grass + l...

Research carried out to evaluate management options and animal production potential of native and improved pastures in savanna regions of tropical America is reviewed, with emphasis on Colombia's Eastern Plains. In areas with limited infrastructure native grasses are the main forage resource and ...
