Southwest ND (05/09/19)

Information from the Southwest region of North Dakota.

Similar to last spring, Mother Nature has been indecisive. According to NDAWN the bare soil temperature in Dickinson reached 50°F on April 8th, but 2 days later it was back in the 30’s. It reached the 50’s again on April 19th but has since dropped again after snow and cold weather hit the region April 27th. As of noon on May 7th, the 4” bare soil temperature on NDAWN is at 44°F.

Many have adequate moisture so far; all are hoping it stays adequate throughout the growing season. According to NDAWN from April 1st to May 6th Dickinson received 1.4 inches of moisture. Over the same period, Beach received 1.67 inches, Bowman 1.37 inches, Hettinger 1.41 inches, Mott 1.34 inches, and the Dunn county station received 0.96 inches.

Small grains, pea, and canola acres have been going in over the past month. There are farms throughout the region that have planted all of their wheat and there are some just starting. Many are pushing to get their canola and pea acres in before the crop insurance deadline. While soil temperatures haven’t been ideal, there are some corn acres planted already as well. With the cold wet soils there is concern for seedling diseases. For crops like corn or soybeans especially, be sure to think about the soil conditions. If the seeds take in cold water (below 50°F) it can cause injury resulting in stunted plants and stand loss.

As more are beginning to see acidic soil issues in the region, if you see stunted plants in a part of the field be sure to take a soil sample from 0-3” and 3-6” to check the pH. This year we will be testing a range of different wheat varieties to see how they perform under acidic conditions. In addition, a field trial, sponsored by the ND Wheat Commission, designed to address this issue will record the effects of different rates of beet lime on wheat planted in acidic soils.
