It was proved that the features of landscape, structure and chemical composition of soil influence on shrinking of Pinus sylvestris at the territory of NNP "Podilski Tovtry". The researched soils enough provide by humus (2.05-3.63%), but have low content of phosphorus and excess of calcium and magnesium content. On depressed state pine plantations influence leaved species, which for higher temperatures differ by intensive development of vegetative organs and create the natural compete to species of pine in phytocoenosis. The compacted soil prevents the normal growth of pine. At the compacted soils life processes are slower, is delayed root growth, worsening the supply them by water and air, which can cause shrinking of pine.
