Concentrations of sodium, calcium, magnesium, potassium, phosphorus and nitrate were measured in throughfall under isolated douglas fir (Pseudotsuga menziesii var. glauca) and Rocky Mountain juniper (Juniperus scopulorum) trees in northern Utah for 39 storms in 1970 and 1971. Concentrations were 3-16 times greater under the trees than in the open. Throughfall under douglas fir invariably had higher concentrations than that under juniper. Since most of the chemical input occurs as dry fallout between storms, surface area and form of the canopy are believed to be the prime factors influencing throughfall chemistry in this region. 15 references, 2 figures, 5 tables.
