Prescription Map based on Soil Properties for Variable Rate Fertilization

The purpose of this study is to develop a comprehensive nitrogen fertilization map by identifying variations in soil components and deriving optimal nitrogen fertilization amounts for precision agriculture that maximizes crop production and minimizes input resources, including fertilizer, water, and labor. The paddy fields of Suchon-ri, Hwaseong-si were compartmentalized into 30 sections, and five types of soil were collected and mixed per section. The soil composition was then analyzed in the soil verification center. Optimal nitrogen fertilization amounts for rice were derived according to soil organic matter and silicon dioxide and the prescription standards for fertilizer use of each crop. Subsequently, the nitrogen fertilizer amount map was created using spatial statistics techniques.
