South Central (8/03/17)

Information from the South Central region of North Dakota.

The region’s NDAWN stations indicate July rainfall ranging from 2.5 inches (Pillsbury) to 0.4 inch (McHenry). Total rainfall from April 1 to August 1 ranges from 10.5 inches (Cooperstown) to 4.2 inches (Wishek). Estimated daily water use by corn and soybean during the past week (July 26-August 1) averaged 0.25 inch/day. Additional soil moisture is needed throughout the region with our row crops being in critical growth stages - moisture stress having major impact on seed yield.

Winter cereal, barley and field pea harvest is in progress and spring wheat harvest is pending. Preliminary reports indicate average or less yield but good quality. Corn planted mid-April through the first week in May is in the blister stage (R2). Based on NDAWN growing degree day units accumulated from a May 1 planting date to August 1, the region’s corn ranges from -80 units (Marion) to 170 units (Wishek) compared to the long-term average. Soybean are in the pod formation stages (R3-4); dry bean in the pod to early seed formation stages (R3-6); and sunflower is blooming (R5).

Continue monitoring soybean fields for aphids, dry bean fields for rust, and sunflower fields for seed-infesting insects.
