The opportunity of using non-conventional composite mixtures as fertilizers for growing one- and two-year seedlings of common pine (Pinus sylvestris L.) was studied in the forest nursery of Sukholozhsky Forest District and Ural Educational and Experimental Forest Farm of the Federal State Higher Education Institution Ural State Forest Engineering University. The composite mixtures were prepared based on the sewage sludge produced by public treatment stations or the products of their thermal processing. Root application of composite mixtures was used with preceding and subsequent soil loosening in the doses of 500 kg/ha and 1,000 kg/ha. After the end of the growing season, 30 seedlings were taken out in each experiment option and their key parameters were measured: stipitate length, root neck diameter, rooting tuft length. The research involved one- and two-year seedlings. The obtained results are of practical importance for the use of sewage sludge newly formed and accumulated in the process of operation of public wastewater treatment facilities.
