Soil Climate

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.

Forage Yields

The improvement of brush-covered rangeland seeded to tame forage species following the application of three herbicide mixtures, with and without fertilizer, was documented. The area was located 193 km northeast of Regina, Saskatchewan, on a Waitville loam in the Grey (Podzol) soil association. The highest forage yields were reported on areas that received either a combination of 2,4-D + 2,4,5-T, 2,4-D + dicamba or 2,4-D + picloram and a yearly fertilizer treatment. The forage yields on the three previously mentioned treatments ranged from 109 to 139 g/m2 and from 394 to 424 g/m2 during the first and second years, respectively, of the experiment, respectively.
