Using organic amendments to restore soil physical and chemical properties of a mine site in northeastern Oregon, USA

Publications Posted on: March 22, 2018
New cost-effective strategies are needed to reclaim soils disturbed from mining activity on National Forests. In addition, disposal of waste wood from local timber harvest operations or biosolids from waste water treatment plants can be expensive. Therefore, using organic byproducts for soil reclamation activities on National Forests may provide an opportunity to increase soil cover and productivity, and decrease restoration costs.

Restoring abandoned mine soil with organic amendments

Science Spotlights Posted on: August 23, 2017
Restoring abandoned mine sites with no environmental hazard or chemical contamination can be expensive because of the inhospitable (hot, dry) environment.  However, the large number of abandoned mine sites located across the west make it imperative to begin restoration activities to help shade streams, reduce erosion, provide habitat, and generally improve soil properties. 

Soil restoration of abandoned mine sites using organic amendments

Projects Posted on: August 22, 2016
Revegetation through organic amendments is increasingly essential to help promote better organic soil and rehabilitation on abandoned mining sites across the northwestern United States. RMRS scientists and their collaborators used biochar, wood chips, and biosolids alone and in combination to determine if they can be used to restore soil physical, chemical, and biological functions on abandoned mines in forests across the western United States. In addition, they are evaluating the best methods for revegetation (seeding vs. planting) so that mineral soil organic matter can be rebuilt over time.
