Innovative Use of Compost in Highway Construction.

摘要

Several State Departments of Transportation (DOTs) have used compost mixtures made of recycled organic materials for erosion and sediment control and establishing vegetation. Research and field trials show that compost works effectively for erosion and sediment control and establishing vegetation. Composted organic material improves the chemical, physical and biologic characteristics of soil on the vegetation growing media. Composted mixtures made of peat moss, bark, processed wood chips, lawn grass chippings, manure and other materials interact to adjust soil PH and fertility necessary for a healthy growing ecosystem.
