Abstract

Loss of nutrients through surface runoff and erosion carried from agricultural land, is a major cause of agricultural land degradation. The purpose of this study was to analize nutrients loss from oil palm plantation caused by erosion. This study was carried out using erosion plots measuring 12 m x 3 m consisting a combination of two factors: type of oil palm inter-row and slope. Surface runoff and erosion values in the active inter-row was higher than those in death inter-row. The nutrients loss of N, P, and K from soil eroded in active inter-row were respectively 0.04; 0.11 and 0.10 ton ha-1 year-1. The total nutrient losses (N, P, K) in dead inter-row were 0.007; 0.024 dan 0.023 ton ha-1 year-1.
