Abstract

An important aspect of research addressing the dynamics of growth and development of tree stands and evaluation of their state is analysis of edaphic conditions in which they grow. In mountain landscapes, soil formation and the state of the soil exhibit considerable patchiness and narrowing of the range of natural factors that ensure the formation of an edaphotope and meet the requirements for its development. The aim of the present work was to study the soil in large stands of Pinus brutia var. pityusa in the Crimean Mountains and to analyze dynamics of its qualitative and quantitative properties. Soil properties were examined in layers of 0…10, 10…20, 20…30, 30…40, and 40…50 cm in sections on sample plots along hypsometric profiles in the largest P. brutia var. pityusa forests in the districts of Ayazma and Batiliman, on Karaul- Oba Mountain, and in the district of Novyi Svet. The results of the study show that in the western part of the P. brutia var. pityusa range in the Crimean Mountains, the growing conditions for this species are more favorable, in terms of humus content and soil texture, compared to the eastern part. The least favorable soil conditions were observed in ecotopes on Karaul- Oba. The present study demonstrates that low levels of moisture accumulation and humus content of the soil are limiting factors affecting the growth and development of P. brutia var. pityusa in the ecotopes of the eastern part of the Crimean Mountains
