Herbicide in Compost

This broadcast discusses aspects of compost contamination by persistent herbicides, such as picloram and clopyralid, which became an issue in 2000. Also discusses subsequent herbicide label and use rule changes. Featured guests: Dave Bezdicek and Mary Fauci from the Department of Crop and Soil Sciences and Dan Caldwell, compost manager for WSU.

Composting of Poultry Offal Demonstration Project

Bary, A., C. Miles and K. Gilbert. 2001. Report of a demonstration project conducted at Middle Farm, Lopez Island.
