PROBLEM TO BE SOLVED: To provide a fertilizing device so designed that the plugging of the fertilizer at a fertilizing nozzle may not occur. SOLUTION: This fertilizing device is provided by installing a controlling device capable of generating the amount of an air flow for discharging the remaining fertilizer in a fertilizing hose from the fertilizing nozzle by increasing the amount of the air flow higher than a normal amount for approximately 1 sec at the starting time of transplanting seedlings at an electric motor for driving a blower for blowing/conveying the fertilizer delivered from a fertilizer hopper 60 installed on a traveling machine body through a delivering part 61, also at the time of starting the transplanting of the seedlings, capable of newly fertilizing after eliminating the remaining fertilizer in the fertilizing hose by blowing out powdery materials such as the remaining fertilizer, etc., at the previous seedling transplanting time in the fertilizing hose, and capable of feeding the more accurate amount of the fertilizer to a field.
