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 if there was no recorded water into soil event in the prior 24 hour period of a respective one 24 hour period; determining from representative data whether there are two respective 24 hour periods of the prior seven consecutive 24 hour periods also have evapotranspiration values within a predetermined range; determining from representative data the rate of soil moisture depletion during the plant moisture uptake period within each respective 24 hour period adjusted for drainage; determining whether the rate of soil moisture depletion during the plant moisture uptake period within each respective 2…
