Microbial Processes > Long-Term Soil Productivity (LTSP) Study > Forest Locations

An International Partnership

LTSP research focuses on the joint role of soil porosity and site organic matter and their effect on the site processes that control productivity. The study is being carried out through a standard series of experimental treatments designed to create varying degrees of stress and to provide measures of biological response and soil recovery. Work centers on national forest lands in the United States and dedicated sites in Canada covering major forest and soil types. The Canadian sites are managed by the Canadian Forest Service in Ontario and the British Columbia Ministry of Forests. The experimental sites are protected from conflicting uses and are dedicated to long-term research.
