AgLine Crop Water Use

The AgLine information system provides crop water use information for the Kings River service area. Information provided for each crop includes:

  • Crop water use for the past 7 days
  • Predicted water use for the next 7 days
  • Total crop water use season to date

These numbers, updated weekly, can be used to assist growers in irrigation management decisions. AgLine includes crop water use data for 31 cropping cases.

Origin of AgLine Data

AgLine’s crop water use data is derived from the California Irrigation Management Information System (CIMIS) station located in Parlier. The CIMIS station provides “reference avapotranspiration” (ETo) with grass as the reference crop.

Given the weather conditions, Grass Reference ETo approximates the amount of water used by healthy, well-maintained grass. Each week, the Grass Reference ETo data is downloaded and entered below:

Grass Reference ETo

Report Date Last 7 Days Next 7 DaysSeason to Date  
(inches per day)(inches per day)(inches)Variance from Normal
8/7/200.270.2739.4417.58 %
7/31/200.280.2737.5216.42 %
7/24/200.270.2635.5710.72 %
7/17/200.280.2733.6712.12 %

The water use for each crop (ETc) is calculated by multiplying the ETo by the crop coefficient (Kc) according to the following formula:

ETc = ETo*Kc

Kc values are factors that correlate the ETo to each crop. Kc varies by crop type, time of year, and cultural practices. Values used by AgLine have been adjusted to match crop water use and grower practices in the Kings River service area.
