Make Uniform Emergence a Priority

From AgVenture's Seeds for Success Agronomy Update, March 2014

Uniform emergence doesn’t just happen; it is the result of a symphony of efforts and meticulous planning.  Right down to the time that seedling breaks through the surface, a seedling that emerges even 4-6 hours after those next to it is likely to be slightly smaller all season. Where one in four seedlings is delayed in emergence by ten days, the overall field potential drops by 6 percent. Uneven planting depth and poor seed-to-soil contact are the primary reasons for uneven emergence. AgVenture strives for perfection at planting.

  • Wait – don’t get out in the field unless conditions are right. Working wet soils can cause compaction issues that contribute to problems the entire growing season and beyond.
  • Manage tillage – carefully monitor tillage depth and consistency
  • Downward pressure - seeding depth and consistent seed-to-soil contact are greatly influenced by planter down pressure. No matter what type of system you’re operating, manage down pressure to assure you have enough force to achieve the proper planting depth, but not so much that sidewalls compact.
  • Seedbed with adequate moisture – planting into soils at field capacity provides the seed an ideal environment for germination.
  • Mind the Residue – residue can impede uniform emergence. It causes variable soil moisture and temperature which can contribute to uneven emergence. Consider using row cleaners to optimize conditions for germination.
  • Depth and spacing – seed depth and seed spacing must be accurate to achieve an ideal plant stand. Work for perfect consistency.
