Animal Manure Management

Recycling local manure nutrients before purchasing fertilizer is key to protecting the environment. Manure can be an economic “Win”, due to its fertility value, and a soil quality “Win”, due to its organic matter.  But it can also be a community risk, due to odors and pathogens. Our live educational programs, online courses, and resources provide science-based information on economically viable, environmentally sound manure handling systems that also comply with all regulations.

Precision Manure Application on Display at Manure Expo

Precision manure application is an important trend in managing animal manures.
While the North American Manure Expo may not reach bucket level status for your vacation plans, for anyone replacing or upgrading equipment for managing manure, it is the place to be. One emerging theme common at this year’s Manure Expo was “Precision Manure”. This article will share a few observations around my conversations with vendors and manure applicators on “Precision Manure”.

Fate of antimicrobial resistant bacteria and genes in manure storage

graphic with question posed as to whether human diseases can be caused by manure
Manure storage and its application on crop land may contribute a form of environmental contamination: antimicrobial resistant bacteria. These bacteria in manure are perceived to cause diseases in humans through environmental contamination. However, a recent study in University of Nebraska-Lincoln feedlots near Mead, Nebraska concluded that long-term manure storage as static stockpiles has the advantage of inactivating antimicrobial resistant bacteria, and it has potential to reduce antimicrobial resistance genes.

Sharing Animal Agriculture's Sustainability Story

Visual illustrating agriculture’s circular economy for managing C, N, and other nutrients.
Animal agriculture often endures criticism from neighbors and consumers relative to sustainability. But when it comes to management of carbon and nutrients, animal agriculture has a positive story to share. Many environmental and sustainability organizations promote the importance of a “circular economy” for increasing sustainability. Those engaged with Nebraska agriculture should help our neighbors and consumers recognize agriculture’s long term practice of implementing this circular economy. This article will help introduce agriculture’s circular economy for nitrogen (N), phosphorus (P), carbon (C), and other nutrients and messages you might share with neighbors and consumers about the Nebraska Advantage for sustainability.

Reducing the Carbon Footprint of Cattle Operations through Diet

Greenhouse Gas Contributors in the US
Agriculture in the United States provides a contribution to greenhouse gases, accounting for 9% of total emissions (US EPA). Animal agriculture is a large contributor. In beef production, both cow-calf operations and feedlots produce these gases. By implementing simple changes in cattle’s diet, though, there are several ways to reduce the number of these greenhouse gas emissions.
