Winter Barley: Nutritional Requirements
Determine lime and fertilizer needs by soil test. Maintain pH between 6.5 and 7.0. Winter kill may be more severe if pH is below 6.5 and/or phosphate availability is low. Barley responds to magnesium if the level in the soil is low. In the absence of a soil test, refer to the most recent soil test available for the field and adjust according to the values listed in Table 1.2-5. Spring nitrogen recommendations are given in Table 1.7-2.
Up to 20 pounds of nitrogen and all of the phosphorus and potassium may be broadcast before planting, or a portion applied with the drill and the remainder broadcast. To reduce fertilizer injury, do not apply more than 15 pounds (nitrogen) or 30 pounds (nitrogen + potash) per acre in the row with the seed.
