How did wide bay soils form
WebBliley and Pettry (1979) did not classify the rim soils found on the Holocene surface but described them as having surface soils of dark grayish brown to brown loamy sand to sandy loam with a subsoil of brown olive or yellowish brown sandy loam or loamy sand, and a sandy or gravelly substratum. The soils had weakly developed B horizons with weak 5 WebAs we’ve discussed, the processes of soil formation are dominated by the downward transportation of clays and certain elements, and the nature of those processes depends in large part on the climate. In Canada’s predominantly cool and humid climate (which applies to most places other than the far north), podsolization is the norm.
