Fertilizer Recommendations for Agronomic Crops in Minnesota

Kentucky Bluegrass, Timothy, Reed Canary Grass, and seed production

Daniel E. Kaiser, Extension Soil Scientist; John A. Lamb, Extension Soil Scientist; and Roger Eliason, Director, University of Minnesota Soil Testing Laboratory

Revised 2011

The fertilizer guidelines for seed production from these grasses are listed in Tables 1, 2, and 3. Except for new seedlings, the suggested fertilizer should be top-dressed to the established stands.

Table 1. Nitrogen guidelines for grass seed production.

Field Status Mineral Soils Organic Soils
  — N to apply (lb./acre) —
  New seeding 30 0
  Established stand 100 40

Table 2. Phosphate guidelines for grass seed production (both new seedings and established stands).

There is no research to indicate that other nutrients are needed in a fertilizer program for grass seed production. Therefore, use of other nutrients is not suggested for this crop at this time.
