| Özet |
| Since the middle of the last century in the Urals of Russia there has been a problem of environmentalpollution by man-made emissions. The purpose of this investigation has been to summarize therecultivation experience of Reftinskaya power plant ash dump. The station was put into operation in1970 and it is the largest one in Russia. Specific feature of the used coal is high content of ash (47%).Daily consumption of coal in winter period constitutes 48 thousand tons. Yearly emissions of thestation constitute 400 thousand tons. The main components of the emissions are sulphureous anhydride (up to 40%) solid stuff (up to 50%) and nitric oxides. The Scots pine (Pinus sylvestris L.)plantations on ash dumps have shown good adaptation and growth. The plantations have formed 143m3/ha total volume at the age of 20 in 1st site index of the recultivation site of the ash dump withash layer up to 7 m. Weakly alkaline reaction of the ash spread by wind promoted soil dioxidationthat results in soil fertility increasing significantly on territory of adjacent stands. Recultivationprocess includes two main stages which are ash dump surface covering with 25-40 cm soil layer,planting with 2-year old Scots pine (Pinus sylvestris L.) seedling. |
