Storage & Treatment Options

Manure storage structures are key to managing manure from animal feeding operations. The quality, composition, and consistency of manure greatly influence livestock manure facility design. Handling characteristics often dictate the type of facility. The University of Nebraska has developed resources for Vegetative Treatment Systems and Anaerobic Digesters.

Do Digesters Affect the Nutrient Content of Manure?

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

Biological benefits of manure application on agricultural soils

Soil quality has been traditionally described in terms of chemical and physical properties; however, soil organisms play an important role in soil health. Some studies suggest that using manure as soil amendment could result in increased microbial biomass, which results in higher soil bacteria, fungi and higher microbial activity. Soil microbial activity is crucial for nutrient cycling, aggregate stability, fertility, and other soil characteristics leading to better crop productivity.

Backyard Biogas Production from Animal Manure: Process and Utilization

This article outlines the process of production and benefits of utilization of biogas from manure for small scale animal farmers, especially those in developing countries. Apart from the sanitary benefit of proper management of manure, this article highlights other benefits that can be derived from animal manure. Thus, encouraging these farmers to store manure from their animal farms for use, thereby changing waste to valuable resources.

Manure Application Options for Beef and Dairy Systems

When it comes to animal manure from feedlots being applied to the land in Nebraska, developing management practices that efficiently uses the nutrients from manure while being environmentally sustainable can be a complicated process. This article introduces some land application approaches for beef and dairy feedlot systems.

Palmer amaranth Seeds in Manure – What Can You Do?

There are several ways seeds of Palmer amaranth can be introduced into your fields. Manure is one of them. This article provides some valuable answers on 1) reducing Palmer amaranth seed in feed, 2) reducing Palmer amaranth seed in manure; and 3) field application of contaminated manure.

Tolkien Teaches Ag: Lessons from Organic Fertilizer Production

On a brisk April day, I was traveling with a group of adventurers through the wilds of the Minnesota country side. We came upon a steep embankment and climbed it so that we might see what lay beyond. When I reached the top, and the crowd around me had parted, I thought for a moment I might suddenly have traded places with Samwise Gamgee, hobbit, because I was gazing out onto a field of what reminded me very much of the steaming slag pits of Mordor.  However, rather than an apocalyptic hell-scape I was instead looking at a premier example of sustainable agriculture.

Video Explains Swine Farm Anaerobic Digester

Nebraska’s first On-Farm Generator is powered by methane that comes from swine manure through an anaerobic digester. The farm is operated by Danny and Josie Kluthe of Dodge, NE and the alternative enterprise is called Olean Energy.

Composted cattle manure is NOT detrimental to sugar beet production

In sugar beet production, most farmers do not have an option of manure as an alternative N source since N availability from manure can occur too late in the season and affect sugar quality. Composted cattle manure as different as it is from fresh manure might be a viable alternative N source for sugar beet production.

Observations of Manure Management on a South Dakota Dairy

As a part of the North American Manure Expo events, participants were invited to tour a family-operated dairy farm located in Hamlin County, SD to witness first-hand some of the improvements that have been added to their manure management system over the past few years. I was able to observe how, in trying economic times for the dairy industry, this family farm has modified their manure management system to get the most out of precious resources – water and nutrients.

Lagoon Closure and Your Environmental Responsibility

Abandoned manure storages present a risk to the environment by accidental overflow or leakage due to lack of management. It is in the best interest of the environment and the property owner, who is liable for any environmental damage resulting from any discharge, whether leakage or overflow, to properly close any unused manure storage structure.

Managing Runoff Holding Ponds During Wet Weather

When designed properly, runoff holding ponds, lagoons, and other earthen manure storage structures are sized to contain manure, process wastewater, and storm water that drain into or fall on them throughout their designed storage period. Excess precipitation, particularly chronic wet weather, can lead to concerns about storages overflowing even when they have been managed correctly.

Lagoon Closure Demonstration

The closure of aged livestock lagoons and earthen manure storage basins needs to be conducted in a manner that controls potential environmental risk and makes economical use of accumulated nutrients in the biosolids. This event will offer a unique opportunity to hear about and see the step-by-step process for planning and conducting a lagoon closure.

Demonstration Projects

Videos and resources on vegetative treatment areas, wetlands, low water stream crossings, and water quality projects.

VTS Guidance Document

Vegetative Treatment Systems for Open Lot Runoff was developed under the leadership of U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) through an Intergovernmental Personnel Act (IPA) agreement, with collaboration from representatives from several land grant universities, USDA Agriculture Research Service (ARS), U.S. Environmental Protection Agency (EPA), Iowa Department of Natural Resources, Iowa Cattlemen’s Association, and private sector representatives.

Methane (Anaerobic) Digesters

A methane digester system, commonly referred to as an AD (anaerobic digester), is a device that promotes the decomposition of manure or 'digestion' of the organics in manure to simple organics and gaseous biogas products.

Small AFO VTS Demonstrations

The Animal Feeding Operation, also called the Livestock Producer Environmental Assistance Project (LPEAP), provides financial and technical assistance to small livestock producers who are concerned about protecting water quality and preserving the environment, but are exempt from current regulatory requirements. The project purpose is to construct on-farm demonstration sites that minimize environmental risk using new concepts and alternative technologies. All demonstration projects are available for viewing by all producers.
