Soil degradation and nutrient balance are important for ecological nutrient management in sustainable agriculture. Soil degradation in term of soil erosion is the single most important environmental concern in the developing countries. Eroded sediment also acts as both a physical and chemical pollutant. It has been become an ecological, social and economic problem. Loss of nutrient by erosion from agricultural areas in a sloping land is one of the major causes of land degradation in Indonesia, yet the process by which the nutrient is depleted has often not been answered by appropriate study. To relate soil degradation to nutrient balance becomes important tool for monitoring sustainable agriculture.
Key words: soil degradation, nutrient balance, sustainable agriculture, ecological nutrient management, sustainability indicator
