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.

Timing Manure Application to Avoid Neighbor Nuisances

Roughly half of all neighbor complaints of livestock odors originate from land application of manure. A weather forecast and a little knowledge of odor dilution can be a powerful tool for keeping your neighbors happy, or at least avoiding those irate phone calls. Picking the right weather conditions for land applying manure, may not improve your popularity in the community, but it can go along way with improving your community’s acceptance of livestock systems.

Is Manure Irrigation Risky Business?

Because of a growing concern about manure irrigation, the University of Wisconsin Extension assembled a workgroup to research the concerns. The workgroup included scientists, public health specialists, state agency experts, farmers, conservationists and others. Over the course of two years, the group gathered and studied the science of manure irrigation, which culminated in a report that contains findings, responses and recommendations. This article will review a few of their findings related to bacterial transport as well as highlight some of the reasons why a farmer might opt to apply manure via irrigation rather than other ways.

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.

Does Manure Benefit Crop Productivity? Environment?

Manure is often viewed by many as an environmental liability. However, if manure is applied at rates equal to or less than the nitrogen (N) requirement of a crop, can manure produce environmental benefits over commercial fertilizer? This was the focus of an Asian research group which summarized the results of 141 published studies from Asia, Europe, and the U.S. comparing manure substitution for fertilizer. This article summarizes the “Take Home Messages” from this research paper.
