Weekly Weather and Crop Update

It was another interesting Weekly Weather and Crop Update from the Southern Research and Outreach Center at Waseca. It was a great week for corn and soybean development. Temperatures averaged 71.1 degrees which was .9 degrees below normal. Rainfall totaled ..36 inches   and that was .67 inches below normal. Growing Degree Units totaled 146 or 4 percent above normal. Since the first of May we have accumulated 995.5 Growing Degree Units and that is also 4 percent above normal. Last year at this time we had accumulated 1045 Growing Degree Units.

Looking at the entire month of June is was also a good month for corn and soybeans as we saw very little crop stress. June temperatures averaged 70.1 degrees and that was 1.6 degrees above normal. Rainfall totaled 4.14 inches and that was .55 inches lass than normal. Growing Degree Units totaled 578.5 and that was 7 percent higher than normal. Soybeans are now flowering so they have reached he reproductive phase. I have not seen any reports of soybean aphids yet but we will have to begin scouting soon. The last 2 years very few soybeans had to be sprayed for soybean aphids. Maybe we will get lucky 3 years in a row?
