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.

Abstract: In order to achieve the object, a communication management system includes: a surveying instrument including a survey unit, a system timer, a control unit, and a communication unit; a management server capable of communicating with the surveying instrument; and a remote terminal capable of communicating with the management server, wherein the remote terminal sets a usable time of the surveying instrument, sets determination on an operating time of the surveying instrument and the usable time, and an operation responding to results of the determination, and makes the management server store these, the surveying instrument transmits an operation start time and an operation end time to the management server, and the management server acquires the operation start time and the operation end time, and compares the usable time and an operating time of the surveying instrument and executes the determination, and executes the operation based on results of the determination.
