Abstract:
1. A groundwater control system for an agricultural field to regulate the level of groundwater in said field according to selected criteria, said system comprising: (a) a buried field drainage tile line extending underground in said field to serve to drain water therefrom; (b) a water flow regulator located in said tile line and having a movable gate that is powered to control the flow of water therethrough; (c) means located in-ground for sensing the purity by measuring the conductivity of the groundwater in said field before the groundwater enters said tile line on at least a periodic basis and for providing output signals representative of said groundwater conductivity information, wherein said sensing means is physically located exterior to said tile line and said water flow regulator; (d) processing means for receiving said groundwater conductivity information and providing output signals to said flow regulator to control the position of said gate for meeting said selected criteria; and (e) a communication link linking said processing means, said sensing means and said flow regulator, said link comprising satellite receiving and transmitting means.
