Abstract:

This study investigated the use of foliar analysis for identification of limiting nutrients in a forest site study in Pinus resinosa Ait. plantations. Application of multiple regression analysis to foliar nutrient data from a series of stands was tested and appears feasible for isolating independent relations of nutrients with growth. The results of different modes of nutrient expression were compared. The results suggest that some measure of total uptake may be superior to percentages. Various growth measures exhibited different relationships to foliar nutrient levels, calcium was strongly related to height growth, potassium to basal area growth, while volume growth related significantly to soil moisture capacity. Need for further study of the interrelationships between various phases of growth and the factors controlling them is indicated. Some possible causes for the different relationships are postulated, such as seasonal changes in nutrient availability. High correlation between foliage calcium contents and height growth has not previously been reported in studies concerning nutrient deficiencies of red pine.
