Animal Manure Management

Manure application on frozen or snow-covered soil poses a higher risk of nutrient loss through runoff.

As responsible land stewards, farmers, who follow “good neighbor practices,” may save on commercial fertilizer costs while at the same time protecting groundwater from contamination due to nutrient leaching. Properly stockpiled manure stored on field edges can be a “win-win” for farmers and their rural neighbors through addressing two common concerns: runoff and odors.

Current manure application practices have little to no precision application capabilities compared to other modern agricultural equipment. Due to some recent emerging technologies being released on the market, manure application is finally joining the digital age. This article summarizes these new precision manure application technologies.

Supplemental protein has historically been the most expensive component in beef cattle diets. However, over the past 20 years with the rapid expansion of ethanol production and distillers grains supply, rations have changed.

Antimicrobial Resistance (AMR) is a problem currently within public surface water bodies and will continue to challenge animal agriculture. AMR can impair our ability to use antibiotics to fight infections and other ailments. Antimicrobials make their way to our water primarily by ways of industrial waste, manure application, and aquaculture. Using responsible manure spreading practices, runoff prevention, spreading awareness, and partnering with your veterinarian for responsibly using antimicrobials can help aid in the solution.

Manure produced in animal feeding operations is a source of fertilizer that can be used to reduce our dependency on commercial fertilizers. Manure contains several essential nutrients that crops that crops rely on to grow, most notably nitrogen and phosphorus. Proper management of manure before, during, and after land application helps to slow down the contamination of our streams and reservoirs.

Most people alive today have never known a world without antibiotics. Antibiotics became widely used to treat bacterial infections in the 1930s and ‘40s, and were quickly labeled a “miracle drug”. But, as widespread use of antibiotics evolved, so did the discovery of antibiotic resistant bacteria. And we have now entered an era where antibiotic resistance is considered one of the biggest worldwide public health challenges of our time.

Nebraska’s livestock industry can benefit from manure generated in the integrated animal and corn agricultural system. Farmers, who only run crop operations, can also benefit from animal manure field applications.

There are many challenges associated with variable rate manure applications such as variable nutrient content within the manure source and nutrient availability, application equipment, and prescription methodology. However, in many cases, these challenges are outweighed by environmental and economic benefits from variable rate manure applications.

This year’s Land Application Recertification sessions, called Applying Manure Management Concepts On-Farm, are scheduled to be in-person at many locations across the state in June, with one taking place in May in Lexington. Manure trainings earlier this year were held virtually, but we’re making progress, and that means we’re looking forward to seeing everyone in-person for the next manure event.

Vegetative Treatment Areas (VTA) are used in multiple Nebraska cattle operations to help improve and maintain water and nutrient quality. This article will explain what a VTA is and how it works. It will then detail how valuable nutrients contained in the manure will be captured and reused. It will also describe what size of feeding operations should install a VTA. Lastly, it will detail how a producer can get assistance to install one.
