Relationships among soil and foliar nutrients and tree height growth or unit weight yields were examined for three Populus hybrids that were planted on an Edom silt loam soil in central Pennsylvania at densities ranging from 0.09 to 0.46 m/sup 2/ per tree. Independent of clone and growing space per tree, significant nutrient differences were measured in the soil Ap horizon and tree foliage when sampled at the end of the first and fourth growing seasons. In the soil, the level of extractable P was reduced, the amount of exchangeable Ca and Mg was greater, and the soil cation exchange capacity was higher at the end of the fourth growing season. When compared to the first growing season levels, 4-year-old foliar levels of total N, P, K, and Mg were measurably lower and Ca was notably higher after 4 years. Soil bases (particularly Ca), soil or foliar N, and soil P were important total height and fiber yield determinant variables. 5 tables.
