Influence of nutrition and various substrates on spruce seedling growth

Abstract

The results of the influence of main macronutrients (N, P, and K) on growth and development of spruce (Picea abies L. Karst) one-year old seedlings are presented. They were grown in containers, in nursery conditions, on four different substrates. There is a good influence on biogenous element contents, height, root collar diameter, needle length and mass, root mass as well as physiological vitality of spruce seedlings. It was observed that the effect of nutrition depends also on the type of substrate.
