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.

Studies concerned a glassy fertilizer obtained at the Department Materials the University of Mining and Metallurgy in Krakow. The fertilizer is able to supply plants with a wide range of macro- and microelements. The present study is aimed to define the possibility of increasing the utilization rate of phosphorus contained in glasses by introducing into the soil the phosphorus bacteria Bacillus megaterium var. phospateum that had been isolated from the soil in which the experiment was carried out and grown on a mineral medium. The results showed an increased level of phosphorus in the soil of the treatments. By using the results obtained in the present and previous studies it is possible to determine the soil conditions to plants. It is worth mentioning that the residues of the glassy fertilizer from which nutrients have been leached are compatible with skeletal parts of soil and thus do not pollute the environment.
