The possibility of using some coniferous species for the improvement of the characteristics of mine soils
Abstract: On the reclaimed mine soils of the lignite mine “Kolubara” the influence of forest plantations of Japanese larch, Douglas fir and Austrian pine on the revitalization of the soils formed by waste-rock deposition was researched. The total yield of litterfall which is annually transported to the soil surface and the percent of nitrogen, phosphorous and potassium in the litterfall was determined. The following soil characteristics were dertermined: reaction of soil solution, the total amount of humus and nitrogen, as well as the forms of phosphorous and potassium which are available to the plants. It was concluded that the Douglas fir plantations had the most favourable effect on the revitalization of soils, whereas the Austrian pine and Japanese larch plantantions had the significantly less favourable effect on it.
