PROBLEM TO BE SOLVED: To solve a problem that an operator informed of the clogging of a fertilizing nozzle with a fertilizer applicator by an alarm device must stop a fertilizing work and remove the clogged fertilizer applicator by a hand work in usual fertilizers. SOLUTION: In this fertilizer applicator, plural rows of fertilizing nozzles 4 for applying a fertilizer fed from a fertilizer tank 2 on a traveling vehicle 1 to a farm field by a compressed transporting air blown from an air chamber 3 are arranged and installed. A clogging sensor S for detecting clogging of the fertilizer is installed to the fertilizing nozzle, while an actuator 5 for regulating the air flow is installed in the upstream of the air flow. A controlling means C which controls the actuator 5 to send compressed wind stronger than that of the compressed transporting air depending on the detected information of the clog sensor S is installed. A control means for controlling the actuator 5 is installed to the fertilizing nozzle having a happening of fertilizer clogging to intermittently blow a compressed wind stronger than that of the compressed transporting air.
