Abstract
An irrigation control system for land includes a weather station to measure one or more weather conditions in a first area; means to measure rainfall in a sub-area of the first area; and a computer connected directly or indirectly to the weather station and rainfall-measuring means. The computer is adapted to monitor the measurements of the weather station and rainfall-measuring means, to calculate a moisture content value for the sub-area from the measurements and a predetermined moisture loss for the sub-area, and to regulate irrigation of the sub-area.
