Title: CHEMICAL AND PHYSICAL PROPERTIES OF SOME SOILS DERIVED FROM REDDISH BROWN MATERIALS IN THE ATLANTIC PROVINCES
Abstract: Nearly all of the 16 soils from Nova Scotia and New Brunswick that were studied had Ae horizons, acid sola and dense, reddish brown parent materials, but they differed widely in the kind and the degree of B horizon development. Particle-size analyses supported the micromorphological observations in indicating that marked illuviation of clay had occurred in some soils, and weak illuviation in others. In a few soils it was difficult to estimate the extent of Bt horizon development as there were obvious discontinuities in the materials. Horizons having the chemical requirements of Podzol B horizons (Bf), significant accumulations of amorphous Al and Fe associated with organic matter, were found in only three of the soils. None of the soils had a Bft horizon; hence, the subgroup, Textural Podzol, should be eliminated. Bisequa development was evident in several of the soils and one was a Bisequa Podzol. Prominently mottled Bg horizons were the most obvious feature of the Gleysolic soils and some of them had Btg horizons. The bulk density of the fragipan in one of the soils was about 2.0, and many of the parent materials had equally high bulk densities. Free carbonates occurred at depths ranging from 60 to 180 cm in 12 of the 16 soils studied.
