Abstract
There is disclosed a method and system for regulating plant irrigation at a crop field. The method comprises obtaining soil water tension (SWT) data and/or soil water content (SWC) data corresponding to a crop field. The SWT data and/or the SWC data is segmented into three segments. A respective line of best fit is determined for each of the three segments. The intercepts of the lines of best fit are used to determine an irrigation start threshold and an irrigation stop threshold. Devices that control irrigation for the crop field are caused to start or stop irrigation based on the irrigation start threshold and irrigation stop threshold.
