Warm Season Pasture / Hay

  1. Warm season perennial grasses include: Switchgrass, Big bluestem, Little bluestem, Indiangrass, Eastern Gama grass and Side oats grama.  At or just prior to seeding, apply lime, phosphorus and potassium according to soil test recommendations. Do not apply nitrogen fertilizer at seeding. A urease inhibitor is suggested for use with non-incorporated urea-containing nitrogen sources. Warm season perennial grasses are slow starters and nitrogen will stimulate weed competition. If more than 4 tons of lime per acre are required, apply only 4 tons of lime per acre and re-test after two years.
  2. Beginning the spring following establishment, apply 60 pounds of nitrogen per acre when grass begins growth in May and then again in July if additional growth is desired. A urease inhibitor is suggested for use with non-incorporated urea-containing nitrogen sources. No nitrogen is needed for minimal growth or wildlife cover only. Apply recommended amounts of phosphorus and potassium in one application any time during the year.
  3. Summer annual grasses included are sudangrass, pearlmillet and forage sorghum hybrids. Apply 60 pounds of nitrogen per acre at time of seeding. If pearlmillet and forage sorghum hybrids are seeded before June 20, apply an additional 60 pounds of nitrogen per acre as topdressing after harvest in If urea is the nitrogen source for topdressing, some loss of nitrogen may occur, without the use of a urease inhibitor, if applied to moist soils followed by three or more days of rapidly drying conditions without rainfall.
  4. Apply only 30 pounds of nitrogen per acre at seeding for soybeans and millet hay. A urease inhibitor is suggested for use with non-incorporated urea-containing nitrogen sources.
