Effect of Geotechnical and Environmental Properties of
Maryland Compost and Compost Amended Topsoils on Vegetation Establishment and Growth
| 项目名称： | Effect of Geotechnical and Environmental Properties of Maryland Compost and Compost Amended Topsoils on Vegetation Establishment and Growth |
| 摘要： | The Maryland Department of Transportation State Highway Administration (MDOT SHA) has been directed by the Maryland General Assembly to increase the use of compost in construction projects, and to develop specifications that involve compost as a component of compost logs, compost blankets and similar construction related to erosion and sediment control. However, MDOT SHA needs to better understand the potential risks to water quality from high nutrient content of different compost products. MDOT SHA also needs more experience using compost-based products for erosion and sediment control, and a better understanding of the engineering limits of compost blankets when installed on steep slopes or under concentrated water flow. Additional guidance related to effective seeding and soil stabilization in compost materials is also needed. This study will help address these needs and will provide MDOT SHA with knowledge to safely and effectively utilize compost products. |
