Retrospective Theses and Dissertations

A study was conducted in the Tropical Moist Forest Premontane Life Zone in the Puriscal area of Costa Rica to examine differences in soil characteristics in the upper 15 cm of twenty-four paired plots of undisturbed primary forest and pasture. Bulk density and pH were different between the forest and pasture plots. Clay content, total organic carbon and total nitrogen were not different. The twenty-four pasture plots were divided into three erosion groups. There were differences in clay content, organic carbon and total nitrogen between the groups. Clay content of the pasture plots increased with increased erosion, while organic carbon ...
