Szukana fraza: [Streszczenie = "Thereby, even on extremely acid sulphurous mine soils, productive forests can be established. In good agreement with the natural vegetation of the region the afforestation with common oak, sessile oak and small\-leaved lime is favoured for better substrates, like carboniferous loamy sand or loam. On sandy and gravely mine soils with low sorption capacity mixed stands with Scots pine, sessile oak and birch are suggested. The afforestation \(spacing, planting method, mixing proportion\) should be carried out according to experiences from the reforestation of unmined locations"]
