Weekly Crop Update From SROC Waseca
Late Wednesday afternoon the Southern Research and Outreach Center at Waseca released the weekly weather and crop update for the week of April 20 through April 26, 2017. Temperatures this past week saw an average of 51.4 degrees, which was 1.6 degrees above normal. Rainfall totaled 1.42 inches and that was .63 inches above normal. The soil temperature at the 2-inch depth saw an average of 52.1 degrees, and that was 2 degrees above normal. Given the low temperature this morning and forecast for tomorrow, there is no question those soil temperatures will drop.
Some corn was planted at the Southern Research and Outreach Center at Waseca on April 10 and it has begun to emerge. Corn that was planted on April 17 has made progress but is still well below the soil surface. The forecast is calling for a low tonight of 29 degrees, so it is likely the corn that emerged will freeze off. With the growing point underground, it should grow back unless it gets cold enough in the soil that it damages the growing point of the corn. Hopefully the corn that has been planted has very good cold tolerance scores because it is not really going to warm up until later next week.
