Here's the latest weekly crop and weather report from the Southern Research and Outreach Center at Waseca, for the week of April 30-May 6.
Gyles W. Randall, soil scientist, and Thomas R. Hoverstad, scientist, at the SROC compile this information each week throughout the growing season.
"Slightly warmer and drier conditions were experienced this past week. Air temps averaged 53.3 degrees or 1 degree above normal. Soil temps at the 2-inch depth averaged 55 degrees which is a tad above normal.
"Growing degree units beginning May 1 totaled 49 or 3 above normal. Rainfall totaling 0.51 inch (1/4 inch above normal) occurred early Tuesday morning. Available soil water in the zero to 5-foot profile on May 1 totaled 9.0 inches or 82 percent of a full profile.
"Hopefully, the profile will be filled to field moist capacity before July when evapotranspiration normally exceeds rainfall.
"Some corn planted by April 15 is up while some still has not emerged. Residue on the soil surface, which effects soil temperature, is having a distinct effect on emergence. Corn has emerged in residue-free fields, but those with more residue, especially corn on corn, tend to be cooler and emergence is delayed.
"Soybean planting has begun but a few rains have slowed progress. Recent rains have been good for those who applied pre-emergence herbicide to corn. Those who do not use pre-herbicides in corn will need to be diligent about applying postemergence herbicides because the recent rain will wake up weeds, and they will come on strong now."

Temperatures averaged 54.8 degrees, which is a whopping 11 degrees below normal. We set records three days in a row for lowest maximum air temperatures beginning with a 50 degree high on the June 7 and continuing through June 9 with a 56 degree high. Growing degree units totaled only 45.5 which is less than half of what we should expect this week.
