Model of Organic Fertilizer Utilization Made from Local Agricultural Waste as Soil Fertilizer in Riau Province

ABSTRACT In general, land in Riau Province has low fertility due to originated from sedimentary rock material and alluvial material that have a low natural fertility. Application of organic fertilizer is a way to improve soil fertility aside from chemical fertilizer. Sources of organic fertilizers in Riau are abundanly. However, it was utilized optimally. This study aimed to find the utilization model local organic materials as soil fertilizer in Riau Province. This research is divided into two stages.
