Efekt aplikace minerálních hnojiv a organominerálního stimulačního přípravku na výživu, vývoj a odrůstání smrkových monokultur v PLO 29 - Nízký Jeseník

In selected natural forest areas, was observed the effect of fertilizers on nutrition and re-growth of Norway spruce (Picea Abies). There were established two research areas with secured cultures of Norway spruce. The plots were divided into individual fertilizery parcels. Then on the individual variations were applied fertilizer powder series Silvamix (Silvamix R + stimulator Silvamix A) and organomineral product Vermaktiv stimulus. Influence of fertilizers was evaluated one year after the application. The samples were colected periodically (once year) and the morphological parameters (height,thickness) also. It was observed from the results that the application of fertilizers can affect nutrition and re-growth of Norway spruce cultures. However the effect of fertilizers varies depending on ecological conditions of the station.Top influencing fertilizers were Silvamix R + stimulator and Silvamix A
