Calcium content in post-mining grounds in the Łęknica region
Journal Title: Civil and Environmental Engineering Reports - Year 2010, Vol 1, Issue 4
Abstract
The work contains results of a study on the calcium content – subtotal and soluble in 0.1M HCl – in post-mining grounds in Łęknica area. Subtotal content of calcium in the level of forest litter, regardless of the used fertilization during reclamation and the location of the study, was apparently the highest (av. 4108 mg·kg-1 ). With the increasing depth of sampling the calcium content decreased (up to av. 80 mg·kg-1 in the parent material). Similar dependence has been noted to the calcium extracted by 0.1M HCl (av. 382 mg·kg-1 in litter vs. 7 mg·kg-1 in parent rock). Very significant correlation between the content of the both identified forms of calcium in the test soils has been observed.<br/><br/>
