Field and laboratory data are presented on six representative Brown Podzolic soils occurring in the Central Lowland of Connecticut and Massachusetts. The environment of this area has been cited as producing modal Brown Podzolic soils. The soils studied have only a few faintly expressed Bleicherdeor none at all and no visual evidence of an orterde. Little textural profile development was found in these soils. The pH, organic content, and morphology of the profile may be considered characteristic of Brown Podzolic soils. It is postulated that the high silt content in the solum of some of the soils studied is of eolian origin since so little weathering has taken place as indicated by the low clay content and near absence of colloid accumulation in the B horizon. X‐ray diffraction patterns show little to be the predominant clay mineral in the Merrimac and Wethersfield soils studied. Chlorite, montmorillonite, gibbsite, and kaolinite occur in decreasing order of abundance. |
