An experiment was designed to determine the effect of 5 forest soil horizons on the growth of Picea glauca (Moench) Voss and to evaluate the contribution of each horizon and two levels of lime in the rate of organic matter decomposition and availability of nutrients. The growth of spruce measured by the fresh and dry weight was affected considerably by the percent organic matter in the soil. The concentration of nutrients in tops and roots was closely related to the concentration of nutrients in the soil with the exception of Ca and Mg concentration. These two elements showed concentration that were higher in tops and roots of white spruce grown in low horizons. This, however, was associated with a decrease in growth. The organic matter was probably the most significant factor for growth of Picea glauca and the increase in mineral composition of the soil profile (9, 17). |
