The Performance of Oil Palm Productivity and Management of Organic Materials at Various Rain Intensity in Sandy Soil

Climate anomalies marked by the presence of el Nino and la Nina need attention in managing oil palm plantations. These conditions have a bad influence on water conditions, especially in sandy land. The application of empty fruit bunches as organic matter source is expected to reduce the adverse effects of la Nina on palm oil production. This study aims to reveal variations of rainfall intensity and organic matter on the productivity of oil palm in sandy land. Results shows that the application of empty bunches accompanied by vegetation management is useful in maintaining the condition of the sand in holding water on one side and controlling excess water on the other side for 24 months (2011-2012). The application has succeeded in increasing production 23% higher than its potential yield in sandy soil with annual high rainfall (3,700 mm).
