Soil Moisture—Fertility Interactions Related to Growth and Nutrient Uptake of Red Pine1

Martin F. Jurgensen and Albert L. Leaf2

ABSTRACT

A 26-year-old red pine plantation (Pinus resinosa Ait.) supported by Carver coarse sand at 0 to 18 feet above lake level on a peninsula was fertilized with 100 lb/acre of K in 1952. Soil moisture-fertility relationships associated with tree growth and nutrient uptake were examined by (i) total tree chemical composition, (ii) soil chemical analysis, (iii) soil moisture availability, (iv) ground water influence including chemical components, and (v) tree responses to K fertilization. Soil moisture-fertility interactions on tree development were related to depth of ground water: (i) tree height growth, needle area/acre, content of nutrients, and foliar K concentrations were inversely related to ground water depth; (ii) tree growth response to K fertilization was directly related to ground water depth.
