The Newdale Soil Association of Manitoba consists of a number of genetic soil types which are the result of local variations in relief, drainage and vegetation. Seven of these soil types were examined in the field and studied in the laboratory in an attempt to relate their characteristics to the factors responsible for their formation.It was found that the depth of the solum of these soils increased the farther down the slope the soil occurred, because of greater amounts of water entering the soil and the resultant cooler, moister soil climate. The per cent of exchangeable hydrogen also followed this trend. Where local soil-climatic conditions favoured the invasion of trees into the grassland area, the soils exhibited considerable degradation. This was revealed by the marked clay illuviation, the greater per cent of exchangeable hydrogen and the lower amount of organic carbon in the soils found under tree vegetation. Internal drainage had an important influence on the type of soil developed in the depressional areas.
