Keys to Uniform Emergence

Keys to Uniform Emergence
  1.  Uniform Seed to Soil Contact

    • Seeds need complete contact with the soil
    • Ensure all seeds imbibe water at the same rate
    • Factors affecting uniform soil to seed contact:

      • Soil conditions (too many clods, too wet, etc.)
      • Planter closing system not firming row
      • Old crop residue in-furrow (hair pinning)
  2. Uniform Soil Temperature

    • Germination starts @ 50 degrees
    • Seeds need the same soil temperature as their neighbor
    • Factors affecting uniform soil temperature:

      • Planting depth difference within a row
      • Uneven residue cover on the soil surface
      • Soil characteristics
  3. Uniform Moisture in Seed Zone

    • Ensures all seeds imbibe water at the same rate
    • Factors affecting uniform moisture:

      • Soil characteristics
      • Tillage patterns
      • Planting depth difference within a row
