Origin of many thick well‐developed nonpedogenetic texture bands is attributed to deposition in glacial outwash concurrent with the deposition of adjoining layers of sand outwash. Nonpedogenetic bands are thicker, less stratified, finer textured, and more massive and convoluted than pedogenetic bands. Roots of forest trees tend to branch and proliferate in the region immediately above thin bands and penetrate and develop normally in thick till‐like bands. Site indexes for natural jack pine ( Pinus banksiana Lamb.) and bigtooth aspen ( Populus grandidentata Michx.) stands, and stemwood production in red pine ( Pinus resinosa Ait.) plantations are significantly higher on soils with prominent texture bands than on soils where bands are absent or weakly developed.
