Update on Efforts to Restore Water to North Platte River Valley Canal

July 26, 2019
The Gering/Ft. Laramie Irrigation District and the Goshen Irrigation District (Wyoming) held stakeholder meetings this week to discuss the status of canal damage and repairs and how to restore irrigation water to 100,000+ acres. Initial canal repairs have started, with tunnel repairs expected to start soon.

Soil Water Content- and Soil Matric Potential-Based Irrigation Trigger Values for Different Soil Types

July 11, 2019
Keeping a close eye on soil water content in individual fields can help optimize irrigation efficiency. This article explores how to use research-based trigger points for various soil types using soil water content-based sensors or soil matric potential-based sensors. Nebraska research has shown that having 25% more water than needed in the maize root-zone reduced grain yields as much as 15 bu/ac.
