Mixing-vessel composting system at a large swine finishing farm
Abstract
"On-farm manure treatment can be challenging for many animal feeding operations, especially for those who have limited nearby fields for manure land application. To date, very few large-scale animal farms utilize composting as a long-term treatment for liquid manure. Composting is a biological process in which microorganisms convert organic materials into soillike material, which can effectively convert animal manure into value-added products. Compost has been well-documented and proven to be an excellent soil conditioner, which could add organic matter, improve soil structure, reduce fertilizer requirements, and reduce soil erosion potential."--First page.
