An Economical Method to Install Industrial Wastewater Storage Pond Liners

Proceedings Home W2W Home w2w17 logo


Over the past four decades, the number of custom slaughterhouses in Michigan has steadily decreased as the number of livestock producers declined. Those who remain are growing larger as they capitalize on the buy local food craze by providing fresh USDA-approved boxed meats at a meat counter or by adding value to the meats by further processing (i.e.,…

Poultry Mortality Freezer Units: Better BMP, Better Biosecurity, Better Bottom Line.

Proceedings Home | W2W Home w2w17 logo


Why Tackle Mortality Management?  It’s Ripe for Revolution.

The poultry industry has enjoyed a long run of technological and scientific advancements that have led to improvements in quality and efficiency.  To ensure its hard-won prosperity continues into the future, the industry has rightly shifted its focus to sustainability. …

Spotlight on Manure Management in North Carolina and the Atlantic Coastal Plains

Proceedings Home W2W Home w2w17 logo


To provide information about commonly-found manure management systems and approaches in North Carolina and the Coastal Plains, and discuss opportunities for technological innovation in the areas of manure management and nutrient recovery/utilization. Hear from a diverse panel of researchers, animal agriculture producers, and agency representatives who will provide background on the environmental conditions of the region and discuss specific technical considerations for innovative research and development.…

For centuries, farmers have disposed of manure by simply spreading it on the land. It is a natural fertilizer. Today, that practice is no longer considered the best solution. Field spreading is now understood to contribute to a growing global problem of the pollution of water, soil, and air.…

Pathways for Effective Manure Nutriment Management Information Sharing and Education Between Agriculture Professionals: A South Dakota Pilot Test

Why Look at Barriers in Nutrient Management Information Flow?


The issue of manure nutrient management has been the subject of controversy and new policies in recent years as the non-point source discharge of nutrients and bacteria is substantial if manure is not managed properly. Unfortunately, there are barriers between organizations and individuals that prevent the flow of important, timely information between audience types and limits the impact and usefulness of research results.…

Identify and Synthesize Methods to Refine Phosphorus Indices from Three Regional Indexing Efforts


This project was started to work with regional CIG projects to calibrate and harmonize Phosphorus Indices across the U.S., demonstrate their accuracy in identifying the magnitude and extent of phosphorus loss risk, and provide suggestions to refine or improve existing Indices. This research is important to provide consistency among state Phosphorus Indices and their subsequent recommendations.  …

Relationship between Surface Waters and Underlying Stream and Ditch Sediment in Selected Eagle Creek Tributaries

Why are stream and ditch sediment important to water quality?

Best management strategies implemented in most watersheds to reduce phosphorus (P) loads to surface waters have been successful, however, internal P loading within streams and ditches may still provide P to overlying water. Phosphorus retention and release by sediments is important for understanding sediment P status and buffering capacity and for determining the potential environmental fate of sediment bound P in flowing water systems.…

Small to Mid-Sized Dairies: Making Compact Anaerobic Digestion Feasible

Why Consider Small or Medium Digester Projects?

Anaerobic digestion (AD) is an environmentally-friendly manure management process that can generate renewable energy and heat, mitigate odors, and create sustainable by-products such as bedding or fertilizer for dairies and farmers. However, due to economics, a majority of commercially available AD technologies have been implemented on large farming operations.…
