The irrigation crop coefficient relates vine water requirements to climatic conditions. Having an accurate crop coefficient allows farmers to estimate irrigation requirements accurately based on local weather data. Past UC research has demonstrated that the crop coefficient itself can be estimated based on measurements of the ground area shaded by the vineyard leaf canopy at midday. However, previous methods for measuring the shaded area were not practical for commercial use, limiting the use of important irrigation information.
