Animal Manure Management

“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.

Cattle manure is a valuable resource for farmers, as it contains an abundance of macro and micronutrients that are essential for plant growth and development. The nutrients present in manure, such as nitrogen (N), phosphorus (P), potassium (K), and other minerals are essential for soil fertility. One of the most significant advantages of using cattle manure as a fertilizer is that it can enhance the soil organic matter (SOM) content. Soil organic matter plays a crucial role in improving soil structure, water-holding capacity, and nutrient availability. Moreover, cattle manure can also increase the changeable fractions of carbon (C) & nitrogen (N) and enhance soil microbial activity, which is crucial for the decomposition and stabilization of soil organic carbon (SOC). The Knorr Holden plot, located at the Panhandle Research, Extension, and Education Center, Scottsbluff, Nebraska presents a unique opportunity for studying the impact of long-term manure (more than 77 years) applications on soil health and crop productivity.

Many farmers and ranchers make inquiries to Nebraska Extension about prevailing rates paid for various kinds of custom farm services. In addition to the regular biennial custom rates survey, the University of Nebraska-Lincoln’s Center for Agricultural Profitability has launched a new survey designed to provide market rate information for the Nebraska livestock industry. Producers and operators that perform and provide custom services for others, or that utilize custom services and pay others, are invited to participate in the survey.

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.

This year’s 4Rs Field Day will focus on up-to-date research information and demonstrations on all three major crop nutrients: nitrogen, phosphorus and potassium.

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.

Drought is a common occurrence in Nebraska. The UNL Beef Drought Management Planning page is designed to help beef producers design a drought management plan and to provide ideas to consider before and during a drought.

Every month the UNL Animal Manure Management Team produces graphics on the benefits of manure application and manure best practices and we want your help sharing them. The graphics are for educational purposes and for use by the public. Oftentimes the graphics we create include a link to an article featured on the UNL manure website, manure.unl.edu.

Flies are numerous this summer. They drive us all nuts, but are they a problem beyond our annoyance? The answer is yes, flies are more than just a nuisance. Flies can carry and transfer diseases between animals. Additionally, they can create wounds where other diseases can enter. So, how do we control them?

During the Soil Health School, presenters will cover many aspects of the science related to soil health, including foundational soil health principles, the evaluation of soil health management practices, and get to experience many hands-on soil health investigations and demonstrations. As a bit of a sneak preview, this article highlights what Leslie Johnson, Nebraska Extension Statewide Manure Educator will be sharing that day. Of course, she’ll be talking about how manure can impact soil health, but the role she’s the most excited about because it will be the most hands-on, is getting to show different ways of determining root growth.
