The agrochemical analysis of the soil of reclaimed dumps in the quarries of the Yurkivska brown coal basin showed that after their afforestation 40 years ago there were significant changes in the organomineral composition of the soil. It has been established that the forest plantations of Scotch pine, Crimean pine, ordinary robin, common oak, red oak and shrub species in combination with technical re-cultivation of degraded lands increased the content of humus in the upper layer of soil up to 10%. The highest total nitrogen content (up to 232 mg∙kg^-1) was recorded in pine-birch plantings of the V age class. It was established that the forest soils have a weakly acidic and neutral value of water extracts, which is 5.9-6.0. Other soils have a neutral exchange of acidity, which fluctuates within the range of 6.20-6.95. The smallest nitrogen content (up to 46 mg∙kg^-1) was fixed in pure pine plantations with admixture of hardwood.
