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.

Reducing Greenhouse Gas Emissions from Cattle Production

Reducing greenhouse gas (GHG) emissions may seem like extra work that can hurt business, but in reality best management practices for reducing GHG emissions can be economical. These practices may also have other benefits such as reducing unpleasant odors. There are two main areas where producers can reduce significant amounts of greenhouse gases. Best management practices to increase production efficiency and reduce methane produced from cattle digestion of feed can be used alongside manure management techniques.

The science behind 50-degree soil and nitrogen application

Does nitrogen becoming nitrate mean we are going to lose it? No, it takes rainfall or snowmelt in the spring that will cause a leaching event, but it does increase the risk of loss. Certainly, there is a balance between making sure we get our manure applied before the soil freezes and applying too early, but hopefully the information above illustrates a bit behind the science of the 50°F and cooling recommendation.

Precision Manure Application on Display at Manure Expo

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

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.
