    • A method and system for irrigating a field adjacent a watercourse is disclosed comprising a plurality of pumps along the watercourse and measuring from time to time at a plurality of measuring locations the salinity, the pH, the temperature and the turbidity of the water. The measuring locations are different from the pumping locations. A real time salinity, pH, temperature and turbidity at the pumping locations is predicted from the measured values and the pumps selectively disabled or enabled on the predicted salinity, pH, temperature and/or the turbidity. Additionally, there is disclosed an Alternate Wetting and Drying (AWD) method/system for irrigating a field using a pump comprising an outlet supplying water to the field and an inlet connected to a water source. The method/system comprises a sensor placed at a location in the field for sensing a water depth below a surface of the field and transmitting the water depth to a controller located remotely from the sensing location using a wireless connection. The controller enables the pump when the sensed water depth is below a threshold depth and disables the pump when the sensed water depth is above a threshold depth.
    • 公开了一种用于灌溉水道附近的田地的方法和系统,其包括沿水道的多个泵,并且在多个测量位置不时地测量盐度,pH值,温度和 水的浊度。 测量位置与泵送位置不同。 根据测量值预测泵送位置处的实时盐度,pH,温度和浊度,并且选择性地禁用或启用泵上预测的盐度,pH,温度和/或浊度。 另外,公开了一种使用泵来灌溉田地的交替湿润和干燥(AWD)方法/系统,该泵包括向田地供应水的出口和连接到水源的入口。 该方法/系统包括放置在现场的位置处的传感器,用于感测场地表面下方的水深并且使用无线连接将水深传送到位于远离感测位置的控制器。 当感测到的水深低于阈值深度时,控制器启动泵,并且当感测到的水深高于阈值深度时停用泵。
