A study in a 12-year old plantation of European larch on a sandy Podzol on outwash materials revealed significant linear and positive correlations between height growth and foliar concentrations of iron, potassium, magnesium, and phosphorus. Tests on partial regression coefficients for each nutrient indicate that both iron and potassium make significant contributions to the regressions of tree height. But when iron is excluded, then in addition to potassium, magnesium also has a significant contribution to the variations of height growth. From these results, it is tentatively suggested that the growth of young and planted European larch is limited by deficiencies in iron, potassium, and magnesium.
