Winter Barley: Nutritional Requirements
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.
