Physiographical characterization, to determine erodability and your relationship with meteorological drought, in soils of the La Ponderosa farm, Municipality of Monterrey, Casanare - Colombia

Abstract

The purpose of this article is to approach the environmental problems that have been generated in recent years in the entire department of Casanare, through the strong summers and droughts, becoming a threat to the water sources and soils in this area.  Therefore, the development of this research seeks to relate the threat of meteorological drought with geomorphological and physiographic parameters, especially the slopes present on the Ponderosa farm, to determine the areas susceptible to erodability. Using GIS - geographic information system tools, six zones or “paddocks” were determined in which slope ranges were classified between 0 and 10, with zero being the least and 10 being the greatest. In the paddocks called 2, 3, 4 and 6, the areas with the highest ranges, between 6 and 10, were identified, indicating steep to steep slopes, these being the most susceptible to mass movements, runoff and therefore erodability. These factors identified in the present investigation, directly influence the sustainability of the productive activities of the farm such as livestock and in some sections, palm crops.
