Abstract
A fertigation system comprises: a controller that transmits sensor data to a fertigation control server, and that controls a water supply valve, a culture stock solution supply valve, and a discharge valve on the basis of received data; and a fertigation control server that, on the basis of the sensor data received from the controller, calculates control amounts for the water supply valve, the culture stock solution supply valve, and the discharge valve, and returns the control amounts to the controller.
