4 Fluid Journal Summer 1997 Tillage. Wheat and canola were seeded in a zero-till system. On adjacent sites, they were sown on conventional-till lands where 50 percent of the previous year's crop residue had been incorporated into the soil. Fertilizer. Fertilizer sources were: N = UAN (28-0-0), P = APP (10-34-0), K = Muriate of potash (0-0-12), and S = Ammonium thiosulphate (12-0-0-26S). Sampling. Table 1 gives fertility status of sites for 1995 and 1996, based on spring soil samples. On the clay loam soil, both N and P were low. Thus, a yield response to applications of both nutrients could be expected. Nutrient status of the sandy loam soils was also very low, so crop response to applications of fertilizer could again be expected. Weed control was achieved with postemergence herbicides applied at recommended rates. Hoe Grass II was applied on wheat and Fusilade was applied to canola. Persistent weeds in canola were controlled with an application of Lontrel.
