In the area of organic agriculture, water resources maintained by avoiding agricultural practices that cause soil erosion and nutrient leaching, water pollution due to the use of chemicals. Animal waste that will be used for organic fertilizer always managed carefully and composted before use. In addition, the use of chemical fertilizers and synthetic pesticides are also prohibited in organic farming systems.
Guard water quality is a very important effort in sustainable agricultural systems (sustainable agriculture system). The fact indicates that the pollution of ground water (groundwater) and soil surface water (surface water) by nitrate and phosphate become so commonplace in the area of agriculture. Residues of fertilizers and synthetic pesticides and disease-causing bacteria such as Escherichia coli are also frequently detected in aquatic systems.
