This paper reports results of a study on 37 plots that show the relationships of certain physical soil properties to site index (at age 50) of western white pine. Site index is correlated significantly with effective soil depth, depth to the zone of reduced permeability, and the available water‐holding capacity of the top 3 feet of soil. Regression equations and confidence limits at the 5% level of significance are included. Applications of these relationships in forest management are discussed.
