Smooth Bromegrass Fertility

Fertility needs at seeding should be determined by soil test. Soil pH between 6.0-7.0 is best for smooth bromegrass, however it is adapted to slightly alkaline or acid soils (Table 1). In the absence of a soil test, assuming a medium-fertility soil, plow down 0-45-135 lb. per acre and apply 20- 20-20 lb. per acre at seeding (banded if possible). If bromegrass is seeded with a legume, reduce or eliminate nitrogen application at seeding.

Smooth bromegrass is very responsive to N fertilization and requires a high level of fertility for maximum production. If you plant smooth bromegrass with alfalfa or another legume, restrict N applications to 40 or 50 lb. per acre to limit the effect N has on reducing nitrogen fixation of the legume. If smooth bromegrass is grown without a legume, apply 100 to 200 lbs N per acre in split applications of 50 lbs per acre in early spring when the grass becomes green and 50 lbs per acre after each cutting.
