Afşin-Elbistan Termik Santrali Çevresi Hafriyat Döküm Alanlarında Dikili Fidanların Kuruma Nedenleri Üzerine Araştırma

In order to avoid soil erosion in the areas of Afsin-Elbistan Thermal Power Plant Environmental Excavation Casting Standing so far, pine (Pinus nigra) and black locust (Robinia pseudoacacia) planted to the 907 hectares terrain by starting in 1987. In recent years drying out (27%) was observed in these seedlings. This research is aim to determine the cause drying of trees, between the years 2012-2013, physico-chemical structure and temperature–humidity of the soil, air pollution and the impact of factors such as harmful insects were examined. In the soil samples, pH (8,5), the amount of lime (24,5%) were observed. Also, it was found to be lack in point of organic material. Besides, ash-slag mixture containing in the higher levels Ni, Zn, Pb, etc. has been observed. Also, when it compared with control plots, soil temperature 1,5-1,7 °C high, while humudity 5-7% low has been observed. Emissions releasing from power plant chimneys composition contains CO2, NO and SO2. These toxic dust compounds created burns in plant leaves and caused to the drying of the leaves by pouring. Total, 9 harmful insect species belong to 5 Order have been identified in the wooded terrain but their population level that has been found a negligible effect on the seedlings in drying. As a result; drying of seedlings is thought to arise from the ecological factors such as soil chemical composition, the low level relative humidity of soil and air pollution.
