Abstract: A fertilization assistance apparatus estimates estimation soil nitrogen distribution in a farm field by analyzing color of soil of the farm field in a captured image in which the farm field before planting is imaged. The fertilization assistance apparatus determines whether there is a correlation between the color of soil and growth situation of a crop in the farm field. In a case where there is a correlation between the color of soil and the growth situation of the crop in the farm field, the fertilization assistance apparatus generates basal fertilizer variable fertilization information using the information about the estimation soil nitrogen distribution. The basal fertilizer variable fertilization information indicates a relationship between the position in the farm field and the amount of applied fertilizer at the position in a case where the variable fertilization of basal fertilizer is performed.
