Groundwater

At the end of the season, a nitrate test can help determine whether the crop was under-, adequately or over-fertilized with nitrogen, resulting in the potential to significantly reduce input costs.

With the two consecutive dry seasons in 2021 and 2022, there is likely a considerable amount of unused nitrogen left in the soil, which could be used for the 2023 crop. With the higher fertilizer prices, such fertility adjustments for next crop can be profitable as well as environment friendly. So, it is recommended to test your soil and account for all sources of nutrients for the next crop.

About 45% reported they had had their water tested for nitrates, E. coli, lead, pesticides or other contaminants.

In Nebraska, extreme winter weather can hit us quickly and hang around for extended periods of time. Long periods of cold can be hard on things, but what impact do they have on your septic system, private well/water system? Are there things one can do to minimize the impact?

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.

This UNL research study provides insights on the rotation of annual crops with alfalfa as a highly effective means of reducing nitrate-nitrogen contamination in groundwater.

Extension recommendations for calculating the amount of nitrate-nitrogen in irrigation water and optimal timing of applications to reduce the cost of nitrogen inputs in irrigated corn.

This year's conference will focus on innovative ways to improve water and food security by increasing farmers’ resiliency to a changing landscape.

The Soil Health Nexus is excited to debut two new resources on the Soil Health Toolbox! Two Soil Health Nexus members, Francisco Arriaga, Associate Professor and Extension Specialist at the University of Wisconsin-Madison, and Anna Cates, Assistant Professor and State Soil Health Specialist at the University of Minnesota, recently published a long-awaited whitepaper exploring the connection between soil health and water quality.

Nebraska is no stranger to dry spells, especially during the summer months. Unfortunately, we have been experiencing longer year-round dry spells in recent years that are becoming more severe to deal with. While using water more efficiently is always a good habit to adopt, it becomes more critical during times of drought, even if restrictions are not mandatory yet.
