Low Cost Aerated Static Composting Systems for Small Acreage Equine Operations

Why Study Low-Cost Composting?

The equine industry in Massachusetts, estimated to be over 50,000 animals, is of a size to make significant impact on non-point source pollution. An average horse generates about 45 lb. of manure per day, almost 10 tons per year as well as bedding. Thus, in Massachusetts approximately 500,000 tons of manure plus associated stall bedding are produced each year.…

Antibiotic Losses during Thermophilic Composting

Purpose

Residual antibiotics in land-applied manure and biosolids present a potential threat to public and ecological health, so it is important to determine antibiotic removal efficiencies for manure and biosolids waste management practices and to identify conditions that enhance antibiotic degradation.…

Markets for Composted Agricultural Waste

Why Consider Composting Manure?

Enforcement of nutrient management regulation has forced Maryland farms and agricultural facilities to adopt new waste management practices. Few options exist that are financially sustainable. Regulatory agencies witnessed the unexpected consequence of closing small and mid-sized farms who could not afford to institute new waste management technologies.…

Efficient Utilization of Equine Manure

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

Abstract

South Carolina is home to an estimated 18,000 horse owners, many of which own or house less than ten horses on their property.  Owners of such small facilities regularly obtain assistance from the Clemson Extension service concerning soil fertility, forage options, and in some cases nutrient testing, but there is very little information available concerning efficient utilization of the manure produced from their facility.…

Why Study Manure Land Application and Steroids?

Manure generated from concentrated animal feeding operations may serve as a source of steroids in surface water and adversely impact the development of aquatic ecosystems. The objectives of this research were to determine the amount of steroids and metabolites in manure from beef cattle production pens, and runoff from crop production fields.…

Vermicomposting Animal Manure

Worm Composting

Vermicomposting is a process that relies on earthworms and microorganisms to help stabilize active organic materials and convert them to a valuable soil amendment and source of plant nutrients. Earthworms will consume most organic materials, including animal manure, agricultural crop residues, organic byproducts from industries, yard trimmings, food preparation scraps and leftovers, scrap paper, and sewage sludge.…

Passive Composting of Manure

Passive Composting

Passive composting is probably the most common method used today because it involves simply stacking feedstocks and leaving them to compost over a long period of time. Very little, if any activity is performed on the pile once it has been constructed. Initial composting parameters can be controlled but are not usually maintained during the entire process.…

In Vessel Composting of Manure

In-Vessel Composting

In-vessel composting refers to any type of composting that takes place inside a structure, container or vessel. Each type of system relies upon mechanical aeration and turning to enhance and decrease the duration of the composting process. The goal of in-vessel composting systems is to combine various composting techniques into one controlled environment, which utilizes the strength and minimizes the weakness inherent to other forms of composting.…

Composting Manure in Windrows

Windrow composting

Windrow composting is similar to passive composting although the piles of materials are turned or aerated by mechanical equipment to maintain optimum conditions. Materials are placed in long rows where the actual size and shape of the windrow are dependent upon the feedstocks and type of turning equipment.…
