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.

Basic Biosecurity

Every livestock producer wants to keep his or her animals healthy. Healthy animals grow better, produce higher quality products, and require fewer interventions like antibiotics. Along with keeping livestock and poultry well fed and watered, comfortable, and safe, it is important to keep them healthy by minimizing their exposure to disease-causing organisms.

Manure Regulations

Livestock Waste Regulations in Nebraska are enforced by the Nebraska Department of Environmental Quality NDEQ). NDEQ administers both state and federal (EPA) environmental regulations. The governing regulations are called Title 130, Livestock Waste Control Regulations.

Crop Planning - Manure Nutrient Analysis and Application

Default values for manure nutrient concentrations are typical values, but concentrations can vary substantially from these due to the feeding program, type of animal housing, and manure handling system. Additional variation occurs within animal feeding operations due to time of year and weather conditions.

Crop Planning - Soil Testing

Regularly checking soil nutrient status by sampling and analysis should be part of one’s crop production plans regardless of whether manure use is an option. However, soil testing is especially important with manure application to insure that excessive amounts of nutrients are not accumulating in the soil.

Crop Planning

An annual crop nutrient management plan is needed to ensure an adequate supply of nutrients to sustain profitable crop production, and to balance nutrient inputs (including manure) with crop nutrient needs. Title 130 of the NDEQ requires that a permit application include a nutrient management plan with manure sampling and analysis procedures, soil sampling and analysis procedures, and planned land application rates, methods, and frequencies.

Custom Manure Application

Custom Manure Applicators are becoming more commonly used by livestock producers in the state of Nebraska. While the regulations in Nebraska do not restrict the use of custom applicators or the methods that they employ, it is in their best interest to apply manure in accordance with the permit holder's nutrient management plan. It is, however, the responsibility of the permit holder (livestock producer) to make sure that happens.

Manure Value

Manure is often an under-valued resource. When well-managed and properly applied, it reaps many benefits. The benefits can be seen in the photo to the left, but are not captured in much of the field because of errors in application.

Understanding Water Quality Issues

Manure contains four primary contaminants that impact water quality: nitrogen, phosphorus, bacteria and other pathogens, and organic matter.

Contaminant Pathways

Water quality can be degraded by contaminants contained in manure, from water used at milking centers, from silage leachate, and from open lot runoff. These potential pollutants typically follow one or more possible pathways to water.

Pathogens and Organic Matter

Pathogens, typically microbes (e.g., bacteria, viruses, protozoa, fungi) or parasitic worms, are organisms capable of causing infection or disease in other organisms, including humans, wild and domestic animals, and plants. Several pathogens naturally occur in livestock and poultry manure and under certain circumstances may pose a risk to human health.
