The essence of conducting a forest nursery production is high quality planting material. Its essential element is rational fertilization of plants grown and conscious use of available methods and fertilizer application. Studies on the effects of fertilization on the growth of Norway spruce (Picea abies (L.) Karst.) can be used by foresters to properly choose the fertilizer needed to achieve the target of production. In the research foliar fertilization was applied, by the following means: “EM Naturally Active” (EM Naturalnie Aktywny – Greenland EM Technology) – liquid organic fertilizer with soil microorganisms, “Bioekor for conifers and ericaceous plants” (Bioekor dla iglaków i roślin wrzosowatych) – mineral foliar fertilizer in the form of a liquid concentrate trace elements and natural growth substances, “Ekolist standard” mineral foliar fertilizer in the form of a liquid concentrate. The study was conducted in 2009-2010 in the forest nursery situated in the Forest District Spychowo. Spruce seedlings transplanting was used. Experiments consisted of four objects repeated in four blocks. The fertilization was performed six times – 2009, and four – 2010. The measurements were performed three times. Annual growth of seedlings taken, from height of measurement was calculated. Analysis of the results obtained, did not show statistically significant differences for any of the applied methods of fertilization.
