From Manure to Mapping: Exploring Sustainable Livestock Mortality Management at Waste to Worth 2025

Jillian Bailey, an undergraduate researcher at the University of Nebraska-Lincoln, explores livestock mortality management through her work in the Animal Waste Management Lab and attendance at the 2025 Waste to Worth conference. She highlights the promise of shallow burial with carbon (SBC) as a low-maintenance, environmentally conscious method for carcass disposal, emphasizing its benefits in leachate control and potential for adaptation using various carbon materials. Additionally, research involving GIS and modeling tools like HYDRUS-1D demonstrates how site-specific risk mapping can guide safer placement of mortality management systems to protect groundwater.

From Manure to Methane: A Student's Dive into Anaerobic Digestion and Sustainable Farming

Alexis Samson, a sophomore agricultural engineering student, attended the Waste to Worth Conference where she expanded her knowledge of manure management, especially in the area of anaerobic digestion (AD). She learned that while AD systems can turn waste into biogas and fertilizer, their cost-effectiveness—especially for small farms—can be improved by incorporating food waste from local sources. Presentations at the conference also highlighted advancements in converting biogas to renewable natural gas (RNG), which offers both environmental and financial benefits for producers.

How much water do cattle need and what water problems should cattle producers watch for?

Water quantity and quality is critical to cattle health and performance. Hot weather and drought conditions can impact both water quality and quantity for cattle. How Much Water Do Cattle Need? There is an easy answer, and there is a right answer. A general guideline is that lactating cows need two gallons of water per 100 pounds of bodyweight per day.

Water is a critical nutrient for cattle, especially during hot summer months. Lactating cows may require 20–24 gallons of water per day, while calves need 5–10 gallons. Poor water quality—caused by high nitrates, sulfates, or blue-green algae—can lead to serious health issues or even death. Producers should regularly test water sources and manage tanks and troughs to ensure clean, safe, and accessible water for all classes of cattle.

Calculating the Value of Nutrients in Manure

“How much is this manure worth?” This is a common question from both livestock farmers who are supplying manure and crop farmers who are utilizing it. To answer this question, it is important to understand the difference between gross value and net value. The gross value of manure reflects the equivalent commercial fertilizer value of the nutrients contained in the manure. The net value considers the impacts of application method, transportation, and cropping system nutrient needs as well as intrinsic values that are much more difficult to put a number on. Therefore, this article will focus on determining the gross value of nutrients in manure.

No Matter Where You Live, Submit a Request Before You Dig!

Spring is here and that often means its time start outdoor projects. Whether you are spading in new trees, putting in a koi pond or other excavated landscape features, drilling a new well, or installing a new onsite wastewater system, you want to make sure a ‘Locate Request’ has been submitted to Nebraska811 before digging.

Nebraska811 is the statewide one-call notification center, set up by Nebraska state law. It is the link between people who want to excavate and the underground facility owners/operators.
