Peak water use is here for many summer crops. Check this week's estimates to help guide irrigation scheduling across the Nebraska Panhandle and northeastern Colorado.

The estimated crop water use for Nebraska Panhandle and northeast Colorado crops for the previous week is shown in the tables below. The tables are based on data gathered and calculations made by Gary Stone, Nebraska Extension educator, and Xin Qiao, extension irrigation and water management specialist, both based at the UNL Panhandle Research and Extension Center in Scottsbluff, Nebraska.

Crop water use will vary across the noted areas due to variations in ET, crop growth stage, temperature, soil type, wind and precipitation events. Crop water use will assist growers with irrigation scheduling and efficient water application and use.
