Surface application of this fertilizer negatively affected root development. The introduction of superphosphate and complex fertilizer positively affected the growth of Aleppo Pine. Better result was achieved by superphosphate. Very good lignification of plants was determined by treatment with superphosphate in both investigated species and a positive effect of phosphorous on development or root system. Additional treatment wich "Osmocote Mini"ferlizer had a stronger effect on plant growth than "Osmocote Sierrablen". The applied fertilization had an effect on increased concentrations of relevant nutritional elements in the substrate and plants. Better developed plants of Stone Pine accumulated significantly more nutriens than Aleppo Pine plants. The use of mineral fertilizer had a strong effect on absorption of corresponding nutriens in both investigated species. With a dose of 1.5 kg/m3 "Osmocote Mini" high quality Stone Pine seedlings were cultivated, while in the case of Allepo Pine the dose should be increased. Key words: "Osmocote Mini", "Osmocote Sierrablen", superphosphate, NPK fertlizer 7:14:21, Pinus halepensis, Pinus pinea, growth, seedling quality. |
