Sažetak
The aim of this experiment was to find out dynamics of the nitrogen (N) content in aboveground phytomass on the turf after fertilization of different forms of fertilizers under non–irrigated conditions. The experiment was carried out in warm and dry conditions in the area of Nitra (Slovak Republic). There were included 7 treatments: 1. Without fertilization, 2. Saltpetre with dolomite, Superphosphate, Potassium salt, 3. Turf fertilizer 15–3–8 (+ 3MgO + 0.8Fe + 18S), 4. Slow release fertilizer SRF NPK 14–5–14 (+ 4CaO + 4MgO + 7S), 5. Controlled release fertilizer Duslocote NPK (S) 13-9-18 (+ 6S), 6. Organic fertilizer Condit (5-1-1) and 7. Organic fertilizer Veget (3-2-1). In the begging of the seasons fertilizing by controlled release fertilizer Duslocote NPK (S) 13-9-18 (+ 6S) had a slow onset of action. The opposite trend had use of organic fertilizer Condit (5-1-1) on nitrogen content in aboveground turf phytomass. The nitrogen concentration was statistically higher in variants fertilized with inorganic fertilizer and organic fertilizer Condit (5-1-1) (33,727 mg*kg-1 – 36,737 mg*kg-1) as a non-fertilized turf (28,446 mg*kg-1). Higher nitrogen content in aboveground phytomass was after application of organic fertilizer Condit (5-1-1) into the turf in comparison with fertilization inorganic fertilizers.
