Site index and soils were studied on one .04-ha plot per stand in 50 natural red pine (Pinus resinosa Ait.) stands. Soils were examined to a depth of 3 m. The current year's terminal leader foliage was sampled on 26 plots. The 50 plots were stratified into two groups on the basis of textural B horizon development or textural banding below the solum. Plots having either of these features within 3 m of the soil surface (group I) averaged 2.5 m greater site index than plots lacking these features (group II). Within each group, surface soil (0-25 cm) properties were more closely related to site index than were soil properties of the forest floor, the subsoil (25-100 cm), or total mineral soil to a depth of 100 cm. Multiple regression analysis indicated significant relationships between site index and surface soil N, P, and K for group I, and N, K, and cation exchange capacity for group II. A single regression equation utilizing a dummy variable for group I or II and terms for surface soil N, P, and K resulted in an R² of .79 and a standard error of estimate of .89 m. Foliar N and P were closely related to site index and a multiple regression equation with terms for N, P, and NxK resulted in an R² of .67 and a standard error of estimate of 1.45 m. Growth limitation due to N or P deficiency probably occurred on several plots but no deficiencies of K, Ca, or Mg were evident. Forest Sci. 20:261-269.
