2d: > 4m deep; moderately well drained
2s: 1- 2 m deep
2vs: 0.1 – 1 m deep; rapidly, well and moderately well drained
2w: 0-30% slope; imperfectly drained; Gleyed
3: 0 – 40% slope; 2 – 4 m deep: glaciofluvial; gravelly, cobbly and stony: sandy loam over loamy sand and sandy loam; rapidly drained: Orthic and Eluviated Dystric Brunisol
3d: >4m deep
3w: 0 – 10% slope; moderately well and imperfectly drained; may be gleyed
4: 0 – 5% slope; 2- 4m deep: fluvial over glaciofluvial and morainal: gravelly, cobbly and stony; silt loam over sandy loam and loamy sand; imperfectly drained; Gleyed Regosol and Rego Gleysol
