    Description

    We investigated the effects of three organic amendments on soil properties and seedling growth at the USDA Forest Service JW Toumey Nursery in Watersmeet, MI. Pine sawdust (red pine, Pinus resinosa), hardwood sawdust (maple [Acer spp.] and aspen [Populus spp.]), and peat were individually incorporated into a loamy sand nursery soil in August 2006, and soil properties were sampled periodically for the next 14 months. Red, jack (Pinus banksiana), and white pine (Pinus strobus) were sown into test plots in June 2007 and sampled for growth responses at the end of the growing season. We hypothesized that pine sawdust and peat could be used as satisfactory soil amendments to improve soil conditions and reduce costs when compared to hardwood sawdust in bareroot nursery soils.
