Abstract

The high rates of tropical forest clearing followed by intensive agriculture may significantly degrade the soil’s original nutrient content and chemical composition, reducing future productivity and future restoration efforts. Land use impacts were determined by collecting soil samples from four sites in San Luis, Costa Rica. Three areas presented different agricultural uses, and the fourth was an area of forest, comparatively untouched by human activity. To evaluate existing nutrient levels, six tests were conducted from three soil samples from each site: ph, N, P, K, Al and Fe. Trends were found in that the site with the heaviest land use experienced the most change in nutrient levels compared to the forest soil. The three different agricultural areas displayed differing results, even as they were all within the same farming community, no more than 15m from one another. Las altas tasas de deforestación en los bosques tropicales debido a la agricultura pueden degradar significativamente el contenido original de los nutrientes y la composición química de los suelos, reduciendo la productividad futura y los esfuerzos de restauración. Los impactos del uso del suelo fueron determinados mediante la recopilación de muestras del suelo en cuatro sitios en San Luis, Costa Rica.
