Determines the effects of farmers practice, clean culture, covercropping and terracing on the extent of soil erosion and coffee production. Specifically, the study aims to: a) assess the amount of surface run-off and soil erosion on Adtuyon series with 14-16 percent slope gradient grown to robusta coffee, b) determine the pH, organic matter content, percentage density of the soild on the erosion plots, c) determine the agronomic traits and yield performance of robusta coffee, and d) the economic analysis on the use of soil management practices.
