FERTILIZER STUDIES WITH WHEAT, OATS AND BARLEY GROWN ON GREY WOODED AND BLACK SOILS IN THE PEACE RIVER REGION OF NORTHWESTERN CANADA
In each of 5 consecutive years, 1951–55, 12 fertilizer treatments were made to wheat, oats and barley grown on fallowed land and on binder stubble land cropped to cereals the previous year. The tests were located on three Grey Wooded soils and one Black soil. Fertilizer response of all three cereals...

| Summary: | In each of 5 consecutive years, 1951–55, 12 fertilizer treatments were made to wheat, oats and barley grown on fallowed land and on binder stubble land cropped to cereals the previous year. The tests were located on three Grey Wooded soils and one Black soil. Fertilizer response of all three cereals was greater on fallow than on stubble. Phosphate gave much higher yield increases than nitrogen on fallow. Phosphate and nitrogen gave about equal increases on stubble for the Grey Wooded soils but phosphate gave a greater increase on the Black soil. Differences in yield response from nitrogen also occurred amongst the Grey Wooded soils. A few responses were obtained to potash. |
