The reclamation efficiency of composts and sewage sludge on coal combustion waste deposits from a coal-fired power station put in cylindrical containers with the diameter of 80 cm and the height of 100 cm each has been examined. It was the second phase of the experiment, the first one took place between 2004 and 2006. Pedogenic deposits were fertilized with five different composts and sewage sludge. In the same lysimetric containers the crop-formation efficiency of sewage sludge and composts (from municipal waste) were examined on the following deposits: combustion waste, lime from the flotation of sulfur ore and humus-less light sandy loam. All the aforementioned deposits featured no variant of organic fertilizing. Sewage sludge produced a great vegetation and crop-formation efficiency, yet its growth depended on pedogenic features of the deposits. Coal combustion ash manifested a significant crop-formation and pedogenic potential in all variants fertilized with an organic matter. Yielding developed gradually along with the increase in neutralization of alkaline reaction and concentration of soluble salts. The study also presents the reclamation efficiency of sewage sludge on the following vast deposits: combustion waste, lime from the flotation of sulfur ore as well as on a 108 ha sodium waste dump where crops of voluptuous vegetation are composted.
