Potential Agronomic Benefits of Wood Ash Application on Reclaimed Surface Mined Lands

Abstract

Wood ash is a by-product generated by paper companies, lumber manufacturing plants and utilities that bum wood products, bark and papermill sludge as a means of disposal and/or energy production. Large quantities of wood ash are generated by these industries since wood generally contains 6 to 10% ash. Most of these ashes are landfilled or discarded in lagoons. However, the increasing expense of landfill disposal has led to increased interest in the land application of industry generated wood ash
