3ro~~m t^ottles <br />• 3rcwn m0=t'.e5 dre 1ndlCdtive Of 71e1L3L10n (Bu01 2L 31, lg%3). BrOWn <br />mottles were classified by the t•tunsell Color Sys Lem and by the catagories of <br />contrast, a~undance and size described for the white mottles, above. <br />Rao is <br />Roots are re described b,' an imprc:-iced scheme. Abundance catagories were <br />the same as the abundance terms used for mottles which were described above. <br />Size catagories were: <br />- Fine: Smaller than 0.025 inches in diameter. <br />- P4edium: From 0.025 to 0.05 inches in diameter. <br />- Coarse: Larger than 0.05 inches in diameter. Coarse roots are either <br />above moist zones or ar•e in moist zones arhich are organic and oxidized <br />(not gleyed). Generally, only a few fine roots are found 1oa, in *_he <br />• capillary fringe or in the water table. <br />Field Texture <br />Texture of soils was estimated in the field by hand. Actually field notes <br />are in the Pit Descriptions. Ptechanical textures may be found in Appendix B. <br />Same error in field estimation of texture is to be expected due to the high <br />concentration of silt and due to the saturated nature of the lower portions of <br />the pits. <br />All soils encountered were in the loam to clay range. <br />• <br />
