Alterantives to Chemical Soil Fumigation in Western Federal Bareroot Conifer Nurseries

The objective of this project was to evaluate alternatives to pre-plant soil fumigation with methyl bromide and other commonly-used soil fumigants in seven USDA Forest Service nurseries in the western United States (two in California, Oregon, and Idaho and one in Washington). Alternatives evaluated included bare fallowing (with and without periodic cultivation), several organic amendments (sawdust and composts), use of modified sowing methods and timing, and mulching for erosion and weed control. Different treatments were tested at different nurseries; treatments were selected that would most easily conform to current nursery practices and were based on availability of amended materials.
