摘要： An irrigation control system is disclosed for controlling the irrigation of horticultural plants or crops grown in containers The system includes a beam assembly for supporting the plant media system and a load cell for providing an electrical output signal proportional to the load applied to the beam assembly by the plant media system. The load cell is interfaced with a microcomputer which executes a control program of the present invention. The control program reads the signal from the load cell at selected intervals and signals for an irrigation event if the current weight of the plant media system is less than a predetermined base weight. A new predetermined base weight is calculated and reset after each irrigation event. In this way, the system bases the initiation of an irrigation event on real time, short term, differential weight change of the plant media system due to evapotranspiration, while allowing for compensation of weight change effects due to other factors such as fruit set, plant weight, pruning and harvesting.
