Abstract
The aim of the study was to evaluate the usefulness of glassy fertilizer as a slow-release fertilizer in container cultivation of Taxus × media and Physocarpus opulifolius in comparison with a common Osmocote Exact fertilizer used in nurseries. Glassy fertilizer granulated to Ø > 0.3 mm and Ø < 0.3 mm was applied in two doses: 3 and 6 g·dm-3. Macroelements, pH and EC were analysed for their content in the substrate. The total length of yew annual shoots was determined. Ninebark was measured for height and number of offshoots; it was also subject to quality classification. Osmocote Exact and coarsely-granulated glassy fertilizer showed systematic release of nutrients. The greatest length of annual shoots was marked on yews fertilized with Osmocote Exact and 3 g VitroFosMaK granulated to Ø < 0.3 mm per 1 dm3 of the substrate. Ninebarks fertilized with glassy fertilizer granulated to Ø < 0.3 mm in the dose of 6 g.dm-3 of the substrate showed the greatest number of offshoots. The most valuable commercial material was obtained when the plants were fertilized with 6 g VitroFosMaK.dm-3 of the substrate.
