This paper reports analytical techniques for the determination of the influence of soil on the growth of red pine and white spruce plantations. The ecological homogeneity of the plantation or portion thereof is checked by a transect survey of tree heights and diameters and soil analysis. The estimate of the rate of growth is made on the basis of stem analyses of the average sample trees. The field and laboratory investigation of soil properties is supplemented by foliar analysis and, in the case of hydromorphic soils, by the determination of properties of ground water. The importance of an accurate estimate of the density of nurse stands is stressed. The applicability of suggested methods is illustrated by concrete examples.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
