Profit and Nitrogen Use Efficiency Gain Using Sensor-Guided Fertigation

January 9, 2019
A UNL study of sensor-based and model-informed fertigation treatments confirms that sensor fertigation treatments are consistently the most profitable and efficient methods of applying N compared to current best management practices (BMPs).

Weather Ready Farms: Irrigation Water Management

March 21, 2018
Climate variability, including extended periods of dry conditions and sometimes drought, are common on the Great Plains. When managing under these extreme conditions, irrigators need to understand daily and seasonal crop water use patterns and adopt practices and technology that result in more bushels of grain per inch of water applied.

Field Pea Seeding Rates, Seeding Depth, and Inoculant

March 13, 2017
Grain-type field peas are a cool season grain crop grown as an alternative for no-till summer fallow in a semiarid cereal-based cropping systems such as wheat-corn-fallow and/or wheat-fallow. They are typically planted in mid-March and harvested late-July. This article reports on research conducted on seeding practices and offers recommendations for producers on the economically optimal seeding rate, seeding depth, and inoculant to grow field peas in western Nebraska.
