The savannas of eastern Colombia located in the Orinoco river basin represent 18% of the Latin American neotropical savannas, and those areas that are tillable and closer to markets are subject to considerable anthropic pressure in the quest for intensification. Historically, and even today, beef...

Frontier areas in Latin America have been characterized by land speculation, abandonment and exploitation. This paper analyzes a frontier cattle ranching area in the savanna where intensification has occurred in spite of land speculation. A whole farm livestock production model is used to quantif...

Soil productivity and sustainability depends on the building and/or conservation of an adequate and dynamic equilibrium between physical, chemical and biological properties and processes in the volume of soil explored by roots, so that there is no constraints in the availability of water and nutr...

The paper reviews trends in land use change in the tropics and subtropics of Latin America and the Caribbean, and their relation to the evolution of the cattle industry in the region. It is posited that horizontal expansion is nearly finished, and that cattle sector, and the grasslands that suppo...

Two experiments were conducted in the neotropical savannas of Carimagua, Colombia to test the hypothesis that Brahman females subjected to sustained grazing undernutrition as heifers can attain high reproductive performance as mature cows if allowed to make compensatory gains. In Experiment 1, we...

The Eastern Plains of Colombia (“Llanos”) are made up of acid soils with low nutrient concentrations covered by tropical savannas, but they constitute a very important land resource for the country. The Llanos have traditionally supported extensive beef cattle production systems but are increasin...
