An NE-1441 Project: Proposed Methodologies for Administering a Multi-State Environmental Best Management Practices Survey of Equine Properties


Several states have reported that equine are the fastest growing segment of the livestock industry. Nationwide, equine has increased by 77% since 1997; and it is reported there are approximately 9.5 million horses in the United States (AHC, 2005). Proper management of equine operations requires the adoption of Best Management Practices (BMPs) to balance nutrient production and prevent erosion.…

Case Study of Contaminated Compost: Collaborations Between Vermont Extension and the Agency of Agriculture to Mitigate Damage Due to Persistent Herbicide Residues

Why Study Herbicide Contamination of Compost?

Picloram, clopyralid, aminopyralid and aminocyclopyrochlor are broadleaf herbicides commonly used in pastures due to effectiveness in controlling undesirable plants and the very low toxicity for animals and fish. In fact, some of these herbicides do not require animal removal post application.…

Economical Anaerobic Digestion of CAFO Animal Waste


The application of manure on croplands is increasingly under regulatory scrutiny, especially from impaired watersheds. The challenge facing many small farms is to find cost-effective and innovative solutions for manure reuse whilst responding to environmental, regulatory and public concerns.…

Manure Technology Video Series

Can Video Be Used as a ‘Virtual’ Tour?

Producers are reluctant to adopt new technologies without firsthand experience with the technology. It is particularly difficult to get positive exposure for manure related issues in traditional media. Creative methods are needed to expose producers to useful technologies for handling and treating animal wastes.…

Evaporation Ponds – Waste Storage Facility Design Spreadsheet


An assessment tool was developed to simplify the process of determining minimum waste storage pond (WSP) dimensions in conjunction with assuring adequate evaporation of stored runoff over time. In contrast to typical WSP designs that require intermittent pumping and handling of waste water, evaporation ponds (EPs), as waste storage facilities used to contain storm runoff from feedlots, offer long-term passive management and may be acceptable alternatives where annual evaporation exceeds rainfall and where landowners deem typical WSP designs as impractical.…

The Natural Farming Concept: A New Economical Waste Management for Small Family Swine Farms

Why Look at Inoculated Deep Litter Systems?

The most critical issue facing livestock and other small family operations nationwide is the development and implementation of cost effective pollution prevention technology. Our livestock producers, especially swine, continue to seek a best management practice (BMP) that is effective, economical, and practical, and in compliance with new US EPA laws.…

Converting Manure, Food Wastes and Agricultural Production Wastes into Bio-Secure Fertilizer, feed, and/or beeding


To find a way to completely eliminate bio-hazards in manure, food wastes, municipal sludge, and agricultural production wastes.

What did we do? 

We adapted existing dry extrusion technology to bio-hazard agricultural wastes. To test the hypothesis we developed [ Dry Extrusion Technology can be adapted to convert bio-degradable hazardous wastes into Bio-Secure class “A” fertilizer, feed, and/or bedding more economically, with less environmental impact, greater sustainability, and in less time with a smaller foot print]

Once we proved our Hypothesis we further developed the process to allow the technology to be utilized in a large stationary plant suitable for a large waste generator and in a portable plant that can be used to assist smaller waste generators, such as, most agricultural producers and smaller municipalities.

Natural Rendering: Composting Horse Mortality

Understanding Livestock Composting as there are few methods to safely dispose of livestock mortality

What did we do?         

CWMI has been working on mortality disposal since 1990. Research was completed methodically as new questions arose. We started with large livestock(deadstock) migrated to research on managing animals hit by cars, generally wild animals.…

Manure Management Facilities and Structures for Small Farms

Waste to Worth: Spreading science and solutions logoWaste to Worth home | More proceedings….

Farms large and small deal with similar manure storage issues. Jean Bonhotal of the Cornell Waste Management Institute discusses some of these issues. Siting of livestock waste areas requires many considerations. Other things to be mindful of include various pad types for outdoor manure storages, structures for indoor and outdoor storage, and composting concerns.…
