Abstract

Soil processing is one major importance for silviculture manufacturing. It allows to improve physical properties of soil, its water regime, conditions of a water and mineral nutrition of plants.

Favourable conditions for survival capacity, growth and development of silvicultures are created under scientifically proved system of soil processing for different areas. At present some common tendencies of optimal silvicultural density are reported in scientific works. Quality, due time treatments of silvicultures the natural plantings are deprived of favour to their successful growth. This is a strong advantage of silvicultures over the plants of natural origin. It is claimed that silvicultural treatments stimulate successful struggle of silvicultures with grassy vegetation and water accumulation particularly in forest-steppe and steppe regions. It is known that unevenaged natural plantings of different sizes especially in unfavourable environment conditions suffer from more intensive selfcutting which results a strict trees differentiation.

At present the planting of silvicultures is turns all over the country and in the European part of central and southern regions in particular. This work is devoted to a summary of results of long-term researches of authors on studying growth, efficiency, a structure of the silvicultures created in the European part, in a zone of forest-steppe in comparison with plantings of a natural origin.
