Increased acidity is very often a limiting factor for decreased soil fertility and unfavorable chemical and physical soil properties. Various materials can be used for liming the acidic soils such as natural ones (ground limestone or slag lime) as well as industrial waste (i.e. saturation silt). Fly-ash from Kosovo power-plants appears as a waste material after burning in the reactors. The material itself causes serious environmental consequences, especially because it is hardly remediated, due to its chemical and physical properties. Since 1963, Kosovo power plants have formed huge fly-ash dumps of very poor remediation ability, with over than 200.000mt of fly-ash. But, despite of its low remediation ability, the material has properties to be used in liming of acidic soils. The fact that fly-ash from Kosovo power-plants is alkaline, with a relatively high content of CaO and CaCO3, it is recommended as a material which can be successfully used in melioration of acidic soils. In our experiment we used the soil type Ranker, as a typical acidic soil from the mountain regions of Kosovo. Quantities of applied material for liming were 1, 3, and 5 mtha-1, calculated on volume of experimental pots of 4 liters. The obtained results recommend the applied liming material as the proper material for use in liming the Ranker soil type. Significant improvements of pH and other chemical properties have been reached, after the experiment, as well as better stability of soil structure.
