Sažetak

Even today, the soil used in nursery gardens is still rarely analyzed prior to planting individual horticultural plants. It is not common either, to base fertilization recommendations on actual results of soil analyses. Therefore, an experiment was set up in the nursery garden using the species Thuja occidentalis ‘Smaragd’ (Arbor Vitae) with the objective to check the influence of fertilization to plants growth, comparing fertilized varieties with the non-fertilized one. During the experiment two varieties of a complex fertilizer (NPK 10-20-30) were used. Research results have shown that fertilization using fertilizers, disregarding the quantity used, improved the growth of Arbor Vitae plants in comparison with their non –fertilized variety. Use of 400 kg/ha of NPK 10-20-30 caused the plants to grow 20,8 cm during one calendar year, i.e. 38,62 cm during the experimentation period. Use of 800 kg/ha of NPK 10-20-30 caused the plants to grow 21,51 cm during one calendar year, i.e.40,73 cm during the experimentate period. Chemical analyses showed no significant changes in the soil.
