Animal Manure Management

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.

Logan Hafer, a senior at the University of Nebraska, reflects on his academic journey, research experiences with the Schmidt Lab, and active involvement in various agricultural organizations. In April 2025, he attended the Waste to Worth conference in Boise, Idaho, where he was most impacted by a tour of the Hagerman Fish Culture Experiment Station, learning about Idaho's leading role in trout aquaculture and innovative sustainability efforts like plant-based fish feed. His visit highlighted the importance of responsible water resource management and offered valuable insights into sustainable agriculture and aquaculture practices beyond his Nebraska roots.

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 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.

Nitrogen is an essential plant nutrient but increasingly found in our water. Here is a brief history:

Manure spreaders are essential tools for distributing nutrients to crops to improve fertility and improve soil health. Therefore, achieving an even application of manure is just as important as with commercial fertilizers. Proper placement ensures that every part of a field receives the nutrients needed, leading to healthier crops and soil biology. This guide explains how to use manure spreaders effectively.

Have you ever been overwhelmed by the amount of manure regulations in Nebraska? Or anywhere? This article simplifies basic manure regulations. Manure rules can be hard to remember, but always remember your Nebraska Department of Environment and Energy representative is a great resource. Don’t be afraid to call them if you have questions. And, as always, the UNL manure team is here to help if called upon.

Turning manure nutrients into better crop yields while protecting the environment will be the focus of ten Nebraska Extension Land Application Training workshops being held across the state this February and March.

Applying manure to fields provides a natural and sustainable way to fertilize crops, reducing the need for synthetic fertilizers. It adds essential nutrients like nitrogen, phosphorus, and potassium, improving soil health and promoting plant growth. Additionally, manure enriches the soil with organic matter, enhancing its structure and water-holding capacity. However, there’s a side to manure that many don’t often think about, that is ammonia deposition. Ammonia deposition is the process by which ammonia is returned to the Earth’s surface after being released into the atmosphere.

The 2025 Nutrient Management Calendars are now available from the Nebraska Extension. This easy-to-use record keeping calendar tracks manure-related records for livestock and cropping operations. It serves as a guide for livestock operations that are required by the State of Nebraska to keep records. It was designed to be used by all sizes of livestock operations and includes all records required for operations permitted for the National Pollutant Discharge Elimination System (NPDES).

A manure workshop will be held in conjunction with the Confronting Cropping Challenges programs at two locations, Randolph and Neligh. The manure workshop will help row-crop farmers Save Money and Resist Stress, and it is designed for crop producers using manure on their cropland. You do not need to own your own livestock to attend. Participants can choose to attend either the Confronting Cropping Challenges program, the manure workshop, or both.

When incentives are available for renewable energy and/or practices that reduce carbon emissions, livestock and poultry producers tend to show more interest in anaerobic digesters.  These producers may also be looking to better manage manure nutrients on the farm.  Common objectives are to reduce nutrient content where an imbalance exists – typically an excess of phosphorus (P) – and to optimize the fertilizer value, especially the amount of nitrogen (N) that is readily available for plant use.  Perhaps the most appropriate answer to whether digesters affect the nutrient cont

As the harvest season winds down and cooler temperatures set in, it's time to start thinking about post-harvest plans. For many farmers, this means planning manure application. Manure is a valuable fertilizer and soil amendment, but to maximize its benefits, it should be treated with the same attention as commercial fertilizers. However, some farmers overlook manure in their fertility programs, missing out on its potential.

Nebraska Extension will host a Nitrogen Sources and Water Quality Field Day on August 13, 2024, from 9:30 a.m. to 2:30 p.m., at the Haskell Ag Lab near Concord, NE.
