Nitrogen, Sulphur and Potassium Concentrations After Fertilization on Mixed Conifer Stands in Northeast Oregon and Southeast Washington Item Info

Post fertilization nitrogen, sulphur and potassium foliar nutrient concentrations were examined for several species of conifers. This study found grand fIr (Abies grandis) foliar nitrogen uptake and potassium levels were higher than compared species Douglas-fir (pseudotsuga menziesii), ponderosa pine (pinus ponderosa) and lodgepole pine (pinus contorta var. latifolia). Douglas-fir foliar nutrient concentrations were higher than ponderosa pine or lodgepole pine. The addition of nitrogen alone tends to cause a decrease in foliar potassium levels for all the species examined. Increases in nitrogen foliar concentrations were consistently higher on the nitrogen alone treatments than the nitrogen plus sulphur treatments.
