The region received little rain during May 13-19, with Linton receiving the highest amount at 0.4 inches, according to NDAWN data. Bare soil temperatures at the 4-inch depth averaged about 60 degrees on May 19. The warming soil is allowing farmers to plant many different crops, but also warm-season weeds are starting to emerge including foxtail, pigweed, and volunteer sunflower and soybean. Crop planting progress is widely variable among fields and farms, but the regionís small grain acreage is probably 75 percent seeded and corn planting at 50 to 75 percent complete. Agronomically, grain corn planted after Memorial Day weekend (May 25) has a good probability of producing disappointing yields and high seed moisture. Small grain fields seeded during the first week in May have emerged, while corn plants are struggling to emerge. For example, on May 19 accumulated growing degree day units for corn planted on May 4 at Carrington totaled 86 units, while 180 units are required for plant emergence. Soybean planting is in progress.
