Abstract
Crops for human and animal consumption of many types are well known by their respective growers. Years of experience in the field provide the grower knowledge about a range of conditions that lead to the full spectrum of crop yields and crop quality, and each grower creates a store of knowledge which they can combine with the available measures of those conditions. This disclosure provides a method for indicating the onset of water stress in one or more plants located in a soil the roots of which are within the measurement zone of a soil moisture sensor located in the soil, by determining from representative data of the daily soil water usage and the evapotranspiration value in the region of the crop each day for a predetermined number of 24 hour periods consecutively prior to a stress determination day d by calculating the line of best fit for the daily crop water usage and recorded ETo for the predetermined number of consecutive 24 hour periods. Calculating the difference of each daily crop water usage from the line of best fit. Determining the statistical standard deviation of the differences of each daily crop water usage value from the line of best fit. Determine a predicted c…
