This was the third consecutive week of above normal temperatures and rainfall across southern Minnesota. Temperature averaged 66.1 degrees or 2.8 degrees above normal. Rainfall totaled 1.15 inches, which is 0.28 inch above normal. Growing degree units (GDUs) totaled 112.5 or 9% more than normal. Since May 1, we have now accumulated 2589 GDUs. This is 10% more than normal.

Last year this week was cool and wet with temperature averaging 61.0 degrees and 1.51 inches of rain fell. Last year at this time we had accumulated 2332 GDUs.

Corn is close to maturity and 96 to 99 relative maturity hybrids planted early are mature (black layered). Soybeans are losing leaves fast and both crops show signs that many spots were too wet this season. Crops are maturing unevenly in most fields and the wet areas are maturity ahead of the areas that did not suffer from too much rain.
