A new Nebraska Extension NebGuide clarifies the concept of consumptive use of water with regard to irrigated crop production and provides guidelines for determining the efficiency of new irrigation technology.

Nebraska farmers and agronomists are set to present results of their 2022 on-farm research studies on cover crops, variable rate seeding, starter fertilizer, biological products, seed treatments, variable rate nitrogen management and more.

According to study from Department of Natural Resources researchers, irrigation pivots stained with rust may indicate the absence of nitrate in the groundwater supplying the pivots. This information can potentially be used to help screen for areas for the potential absence of nitrate and, in an ideal world, could indicate areas at higher- or lower-risk for nitrate contamination before it becomes a problem.

In this two-day course, NU experts will be discussing the latest research on soil fertility, precision ag for nitrogen management, cover crop effects on soil, soil carbon sequestration and more.

Some crop growers have always removed crop residue for animal feed and bedding. Crop residue removal should be done in such a way that it benefits the grower without negatively impacting the health and productivity of the soil as well as the environment.
