Harmony Valley compost project
In 1991, organic vegetable growers Richard DeWilde and Linda Halley noticed an increase in foliar diseases after they stopped using composted manures following the sale of their livestock. DeWilde and Halley teamed up with CIAS and Robert Goodman, UW Professor of Plant Pathology, to learn if application of composted dairy and goat manures would increase their crops' health and yield. Their work revealed that composted manures can significantly increase yields of vegetable crops including radishes, beets, and carrots. Some plant diseases were less severe in the plots treated with composted manure.
