Twenty-four plots were established in the summer of 1980 in 16 year old white spruce (Picea glauca (Moench) Voss) plantations on formerly agricultural crop fields of silt loam texture in Patten, Maine. These plots were used to determine the relationships of physical and chemical soil properties to tree growth and survival. Soil and foliage samples were collected in August and September 1980. Tree growth was expressed as total tree height, total basal area, and total volume. Tree survival was expressed as the number of live trees per plot. The soil physical and chemical properties measured were separated into soil profile properties and soil properties.
