Abstract: A technique is provided to enable low-cost control of amounts of fertilizer applied. A control device controls a currently used agricultural machine that applies fertilizer to a crop while traveling through a field. The control device includes a growth data receiving unit, a fertilizer application amount value calculator, and a speed signal generator. The growth data receiving unit receives growth data that is obtained by sensing a growth condition of a crop at each location in the field. The fertilizer application amount value calculator determines an amount of fertilizer on the basis of the growth data. The speed signal generator generates a speed signal to cause the agricultural machine to travel at a speed corresponding to a variable value of an amount of the fertilizer to be applied at each location in the field.
