Rhodes Research and Demonstration Farm
Increasing concern about the impacts of livestock liquid waste handling, treatment, and disposal systems on water quality has caused livestock producers to look for more environmentally benign systems. Hoop structures in conjunction with composting offer a solid manure management option, which can minimize the possible impacts to water quality. Finisher pigs are raised within a deep layer of bedding, which allows for in-situ decomposition of the manure. Manure and bedding from the hoops then can be directly land applied or further composted and used in crop production.
