About Crop Water-Use Charts
|
|
(Above) This photograph is of a typical AgriMet Data collection station. This page provides a key to the crop codes used within the AgriMet data tables. | |
These crop coefficients vary throughout the growing season based on the plant growth stage. The crop coefficients are tied to the actual plant growth stage by three dates: Start, Cover, and Terminate dates. | |
Start dates are the beginning of vegetative growth in the spring for perennial crops or the emergence date for row crops. Cover dates are typically when plants reach full foliage. Terminate dates are defined by harvest, frost, or dormancy. Following is an explanation of the columns displayed in an AgriMet crop water use chart, followed by a key to the crop codes. This same key is offered as a pop-up window on the individual station pages. AgriMet crop water use charts are updated each morning at approximately 6:00 Mountain Time, and reflect ET based on the weather conditions for the previous day. There is also a tabular ET Summary Table daily crop water use for each crop for the entire growing season. |
