Cooler conditions settled into southern Minnesota this week slowing some of the corn emergence that had been seen. Temperatures averaged 47.9 degrees, 5.4 degrees cooler then normal. Rainfall totaled 0.99 inch or 0.13 inch above normal. Growing degree units (GDUs) begin on May 1 and this week we totaled 26.5 or 1.5 less then normal. Soil temperature at the 2-inch depth averaged 49.4 degrees which is 5.3 degrees cooler than normal.
Last year this week was warm and dry. Temperature averaged 58.2 and 0.36 inch of rain fell. At this point last year, we had accumulated 51 GDUs.
April turned out to be a very good month for corn and soybean farmers. Temperatures averaged 48.4 degrees which is 2.3 degrees warmer than normal. Rainfall totaled 1.97 inches or 1.24 inches less than normal. The month allowed many days suitable for field work and much of the state’s corn crop was planted.
Soybean planting is now in full swing. Many have been interested in rolling soybean fields after planting. While this does create a flat surface at harvest time, there can be down sides to rolling soybean fields, mostly in soil erosion potential.
