Overall, the soybean crop looks to have good potential despite the environmental headwinds.

 

Crop Conditions - South-Central Minnesota

- Ashley Storby

Corn

  • Some areas in south-central MN have received double their typical annual rainfall as of early August.

    Ponding on a farm near Alden, MN - June 3.

  • Above average rainfall during the growing season challenged corn planting and timely herbicide applications.

    Ponding on a farm near Albert Lea MN on June 22

    Ponding on a farm near Albert Lea, MN - June 22.

  • Much of the corn crop in the above average rainfall areas is short in height.

    Stress from saturated conditions produced corn with reduced height and low ear placement

    Example of corn in the R1-R2 stage on August 2 near Waldorf, MN. Stress from saturated conditions produced corn with reduced height and low ear placement.

  • Disease onset was early, particularly for common rust. Fluctuations in cool versus warm temperatures has been helpful in stalling disease progress as of early August.

    Common Rust - June 25 - Hartland, MN.

  • Corn rootworm beetle feeding has been evident in some locations.
  • Overall beetle pressure appears to be very low, possibly a product of our saturated June conditions.

Soybeans

  • Soybeans endured the same challenges with timeliness of planting, spraying and replant as corn experienced.
  • We did have pockets of soybean death from Phytophthora.
