Szukana fraza: [Abstract = "With the increasing depth of sampling the calcium content decreased \(up to av. 80 mgźkg\-1 in the parent material\). Similar dependence has been noted to the calcium extracted by 0.1M HCl \(av. 382 mgźkg\-1 in litter vs. 7 mgźkg\-1 in parent rock\). Very significant correlation between the content of the both identified forms of calcium in the test soils has been observed."]
