Abstract

The research focuses on the development of the most effective activated composts for cultivation of standard planting material of conifers with a high mycorrhizal degree of root systems. The purpose of the research is studying the influence of various activated composts on the silvicultural efficiency of seedlings cultivation of conifers. The degree of readiness of cow composts with regard to the dynamics of the content change of fertilizer elements is established in a laboratory environment. Practical significance of the results of the research consists in providing the forestry enterprises and forestries by standard planting material with a high degree of their survival ability on a planting area. The research is conducted according to the standard techniques and governing documents. These investigations make a considerable contribution to the forest growing and can be used in the forestry production. The silvicultural efficiency of the cow composts with activated and other targeted additives in the forest tree nurseries is established. The cow composts introduction leads to the growth and development of parameter increment of a Scots pine seedling by a factor of 1.4–2.5, to the strengthening of the degree of its root system development by 25–30 % and expansion in length in 1.3–1.5 times. In addition the activity of complex coralloidal form formation on roots of mycorrhizal endings increases twofold and the growth of the aboveground part of the pine seedlings according to the height index of a stipitate by a factor of 1.3 on average increases as well. It was established that the introduction of composts based on coniferous bark with activated and other targeted additives into the soil of a forest tree nursery is highly effective.
