2021 SureForce™ Corn Trial – MN

What We Were Testing For: 

To evaluate SureForce™ at three different treatments in the field and the formation of uniform seedbed conditions across the different treatment types. The agronomy team will evaluate uniformity of emergence and evaluate seedling depth during the 2021 growing season. Yield data will be collected at harvest to determine the efficacy of the down force treatments and develop best management practices for growers to utilize on their own farms based on the outcomes of these trials. 

Early Season Findings:

Seed depth varied slightly between treatments. The shallowest planting occurred at the manual setting of 100 lbs. 

Dry soil conditions at planting hindered the development of a good seed trench. Under dryer soil conditions, more downforce was required to maintain the seed trench quality preventing sidewall collapse.  It will be interesting to compare the different down force treatments this fall with final yield results. 

This map shows down force treatments captured using AgFiniti for this SureForce™ trial.

Trial Location:
Southwest Minnesota

Product Tested:

Crop Type:

Cropping Practice:

Heavy DF Setting Seeding Depth

Medium DF Setting Seeding Depth

Manual DF Setting Seeding Depth

Outlying Factors:

As seen in the pictures above, seed depth varied slightly between treatments.  The shallowest planting occurred at the manual setting of 100 lbs.

This field experienced cold weather during the germination process. Corkscrew symptoms, which is a deformed elongation of the mesocotyl in corn, were caused by these cold temperatures. Germination and emergence is slower when temperatures fall below 50°F. Even with the cold temperatures that this field experienced this spring, the actual population is acceptable from the targeted seed drop.


Additional insights coming this fall!

This is a summarization of data collected in one year and represents only what happened across the tested field in 2021.  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.
