PROBLEM TO BE SOLVED: To provide a work vehicle, such as a seedling transplanter and seeder, which can optimize a fertilizer amount to be fed to a farm field, can grow a crop as desired, and at the same time can suppress surplus fertilizer consumption.SOLUTION: The work vehicle includes: a fertilizing device feeding a fertilizer to a farm field a controller 300 controlling a fertilizing amount fed by the fertilizing device and an environmental state detection device 308 detecting a work environment of a work place. The controller 300 controls the fertilizing amount according to a detection value of the work environment of the work place detected by the environmental state detection device 308, corrects the detection value of the work environment of the work place detected by the environmental state detection device 308 according to a vertical motion amount of a front wheel detected by a vertical motion sensor 310. The controller 300 controls the fertilizing amount fed by the fertilizing device according to a corrected detection value of the work environment.SELECTED DRAWING: Figure 6
