DescriptionEffects of P, K, Ca, Mg, S, Co, and Mo fertilizers on growth and foliar nutrients of red alder seedlings potted in Grove, Bunker, and Wishkah forest soils were determined. Growth in Grove soil was stimulated most by P, Ca, and P + Ca + Mg + K + S. Growth in Bunker soil was improved only by P. In Wishkah soil, best growth was obtained when P was used alone; all fertilizer mixtures produced less growth. Results indicated the potential of fertilizer to increase alder production and suggested caution in using fertilizer mixtures because they may materially reduce growth response.
