The young trees were grown at a spacing of 25 cm × 1.0 m on a podzolic soil. The study focused on the differences in diameter and height of the maiden stock, the branch number, lateral shoots in the crown and their length, among treatments with various bioproducts applied to the maidens once or twice, such as granulated manure, Micosat, Humus UP （humus cultivated）, Humus Active ＋ Aktywit PM （positive microorganisms）, BioFeed Amin, BioFeed Quality, Tytanit and Vinassa. The control maidens were not fertilized at all, or fertilized with NPK （nitrogen, potassium, phosphorus）. The first time when these products were applied in the nursery was mid-May, and the second time was one month later. Repeating the application of humic preparations （vermiculites） and a formulation containing mycorrhizal fungi （Micosat） gave better results than applying them only once, but in the case of BF Quality and the preparation Tytanit treating the plants for the second time did not increase their growth vigour compared to the plants treated only once. And the effectiveness of the biopreparations was different for the treated cultivars changed.展开更多
