Producers can evaluate spring-stored moisture and plant populations to better predict yield potential in the spring than at planting, so N needs by the crop can be better determined. Placement of P fertilizers in the root zone is important because P is not very mobile in soil. The critical level of chloride is 40 pounds/acre in the surface 2 feet of soil. Winter wheat fertilization recommendations in North Dakota previously were similar to spring wheat and durum. ), because wheat nitrogen needs are quite modest, until stem elongation and rapid growth begins. Under rare situations some sandy soils may require S applications; the chances of getting a yield response to S fertilization increase when the soil pH is 7.5 or higher and the soil organic matter content is 1.5 percent or lower. 0000106890 00000 n 0000105331 00000 n 0000105232 00000 n Suggested N rates for dryland wheat are given in Table 1 at an expected yield of 50 bushels per acre.
