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
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.
Nebraska Extension is calling on municipalities, lawn care companies, farmers and others to donate or sell wood chips, hay, lawn waste and other carbon sources to livestock producers hit hard by Highly Pathogenic Avian Influenza (HPAI).
University of Nebraska-Lincoln (UNL) has changed recommendations for crediting nitrogen following manure applications for field crops. New research has shown that most manures are similar changing the organic-nitrogen availability factors.
When talking about manure's value, one needs to think about a variety of factors. Most folks think of fertilizer nutrients as manure’s primary value or MVP, but it takes more than one or two star players to make a great team. As such, manure wouldn't be as great as it is without other characteristics like the added organic matter that you get when applying manure, or the microbial community that is added to your field with that application.
Managing manure for economic and environmental benefit is based, in part, upon our ability to efficiently recycle manure nitrogen (N) between animals and crops. This article introduces University of Nebraska-Lincoln (UNL) proposed changes in recommendations for crediting manure nitrogen in a crop’s fertility program.
If you raise livestock or poultry, you know it is in your best interest to keep your animals as healthy as possible. Healthy animals grow better. They also produce higher quality products, like meat, milk and eggs, and produce them with greater efficiency when they are healthy. So, along with keeping animals well fed and watered, comfortable, and safe, it is important to keep them healthy by minimizing their exposure to disease-causing organisms.
Flood-soaked grain or hay is almost certain to be contaminated, making it unfit for use as food or feed. This summary describes regulatory considerations and recommended actions for management of agricultural grains and forages deemed unusable for food or feed following flooding.
Many areas of Nebraska have experienced higher than normal precipitation events recently, with some areas receiving rainfall that far exceeded a 25-year, 24-hour storm event. This abnormally wet weather pattern has caused drainage and flooding issues in some parts of the state. The Nebraska Department of Environmental Quality and Nebraska Extension would like to remind producers and landowners to be vigilant in monitoring lagoon and runoff holding pond levels.
Five methods are approved for the routine disposal of livestock carcasses in Nebraska: composting, burial, incineration, rendering and land-filling. In an emergency situation – such as when livestock losses occur due to extreme weather or another non-disease related event – these five options still exist, but may not be suitable in all situations. The feasibility of carcass disposal via incineration, rendering or land-filling will depend on existing infrastructure or resources and, therefore, will not be discussed here. Acceptable processes for emergency composting and burial of livestock carcasses are described here.
If you are an owner or employee on a permitted animal feeding operation, you know very well that maintaining complete and accurate manure management records is necessary to comply with your nutrient management plan (NMP). While you may have enough land within your operation to utilize all manure nutrients produced, it is quite common for manure to be transported from a livestock operation where it was produced to a neighboring crop farm for land application.
Cedar trees are spreading into grasslands and reducing forages that support cattle grazing. The Nebraska Forest Service is promoting management practices to keep the trees from spreading outside of their usual habitat and into grasslands and areas along the banks of rivers and streams (called ‘riparian forests’). So what do cedar trees have to do with manure? Since 2015, two resourceful farmers have generously given up a few acres of their fields for UNL researchers to test various applications of mulch alone or co-mingled with cattle or swine manure.
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.
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.
Soil health management refers to the preservation and improvement in soil physical, chemical, and biological properties to maximize the productive capacity of soil. Cover crops and reduced tillage are promoted for improving soil health; however, soil amendments such as application of livestock manure and municipal biosolids have received less attention as a soil health improvement practice. A literature review, funded by the North Central Region Water Network and the Soil Health Institute, was conducted to summarize and discuss results of studies reporting chemical, physical, and biological soil properties from application of livestock manure, animal by-products (i.e. compost), and municipal biosolids and to identify further research needs.
A Nebraska Extension pilot project is assisting pork producers in calculating their swine farm environmental sustainability footprints in a joint effort with the University of Minnesota Extension.
