Keeton Seed Firmer Study

Keeton Seed Firmers gently press every seed into the bottom of the trench to tuck it firmly in the soil,

Key Points

  • Yield Increase: At the PTI Farm, utilizing the Keeton® Seed Firmer has led to an average yield increase of 3.4 Bu/A.
  • Economic Increase: At the PTI Farm, utilizing the Keeton Seed Firmer has led to an average economic increase of $14.33/A.
  • Downforce Correction:  Keeton Seed Firmers show significant yield increases when downforce is too light or we lose ground contact during planting.
  • Quick ROI: Keeton Seed Firmers can often pay for themselves in 40-60 acres. In 2021, we saw a break-even point at 59 acres for corn and 41 acres for soybeans.

Tuck in your seeds!

One of the most common issues at-plant is when seeds don't land at the bottom of the furrow where they belong. This can create an air pocket underneath the seed, not allowing it to take up as much moisture as it should.

We all want simultaneous germination and emergence, but how can we achieve it?

With its unique, in-the-trench design, the Keeton® Seed Firmer gently firms seeds to the bottom of the V-trench. The end result is even depth, correct seed-to-soil contact, and most importantly, uniform germination.

How much does it really matter, though?

In multiple years of research at the PTI Farm, we have seen that downforce control and seed firming matter when maximizing yield.

In these featured studies, we're walking through how we've seen Keeton Seed Firmers solve the issue of seed-to-soil contact, the connection of downforce scenarios, and the overall impact on yield.
