COLOR AS A CRITERION FOR THE RECOGNITION OF PODZOLIC B HORIZONS

Three hundred and fifty-three B horizons from acidic, well- to imperfectly drained soils from northern Ontario were sampled in an effort to test and possibly refine the current color and pyrophosphate-extractable Fe and Al criteria as presently used in the Canadian System of Soil Classification. Each of the soils sampled displayed podzolic morphology in the form of reddish brown to brown B horizons that became yellower and/or paler with depth …
