Foliar analysis is useful in indicating soils deficient in K for normal growth of certain conifers. Exchangeable K in Adirondack sand plains of glacial outwash origin was found related to K in foliage of Pinus strobus, Fagus grandifolia, Populus tremuloides, Fragaria virginiana, and Andropogon gerardi . Foliar K decreased as the season progressed for Pinus strobus, Acer rubrum, and Prunus virginiana . Plants fertilized with KCl were analyzed for comparison. Exchangeable K, acid‐soluble P, total N, organic matter, and pH analyses for soils are reported.
