Groundwater

Groundwater is vital to the “Good Life” in Nebraska. It maintains our agricultural economy, supplies water to streams and lakes, and provides drinking water to municipalities and rural households. Nebraskans pump groundwater out of the High Plains aquifer and many other aquifers across the state. The vast majority of groundwater is used for agricultural production.

Protecting Groundwater by Managing Animal Manure Products

A monitoring well
Groundwater is often the main source of drinking water for rural communities, especially in the Midwestern United States, so it is important to keep that water at levels that are safe to drink while minimizing environmental impacts. Although animal manure has many benefits to farmers, it can contaminate groundwater supply if not managed properly. This article discusses important considerations when storing and applying manure and includes requirements for testing of well water.

Dietary Strategies to Reduce Nitrogen and Phosphorus Excretion in Feedlot Cattle

Cows at Feeding Station
Dietary nutrients, specifically nitrogen and phosphorus, are excreted in manure from feedlot cattle. Dietary strategies, including calculated protein supplementation and phase-feeding programs, can be implemented by cattle feeders to decrease nutrient excretion and improve nutritional efficiency of the animal.

Caption:  A simple overview of how the water softening process works. As hard water enters the water softener, it filters through a resin that is supersaturated with a sodium (Na) brine. The calcium (Ca) and magnesium (Mg) in the hard water attach to the resin beads and are exchanged for sodium (Na), thus making soft water for use throughout the home. Over time, the exchange resin becomes saturated with Ca and Mg and has to be regenerated with the Na brine solution so an effective water softening process can continue.
