2020 Kansas SureForce Trial

Agronomically Speaking

Kansas SureForce Trial

  • Year:  2020
  • Trial Location:  Southern Kansas
  • Product Tested:  SureForce
  • Crop Type:  Corn
  • Cropping Practice:  Conventional Tillage

Trial Purpose/What We Were Testing For:  Determine the influence of SureForce on uniform corn emergence and consistent seeding depth

Outlying Factors:

  • Extremely dry this summer which influenced the trial outcome this year.


  • There was a yield increase of 2.4 bu/ac compared to the control of 100 lbs. manual downforce. However, there was no significant difference which means that there may have been other outside factors that we were unable to control that influenced the results.

Bushel Advantage: 2.4 bushel advantage when using the Medium SureForce setting compared to the control.


Additional Trial Information and Maps:

* Corn price was $3.80/bu when the trial summary was analyzed.

Difference in seeding depth per treatment.  Auto (Medium setting) left side and 100 lbs. manual setting on right side of photo.  Notice the difference in plant height.

This photo shows the differences in root development of the three different treatments in this SureForce trial. 

  • Two plants on the left are the Heavy manual (280 lbs.) setting,
  • one plant in the middle is the light manual setting (100 lbs.), and
  • the two plants on the left is the Auto (Medium setting).

This is a summarization of data collected in one year and represents only what happened across the tested field in 2020.  It is not a rigorous evaluation of factors that may or may not influence yield.  Results may not predict future performance and may not be complete.
