Southwest ND (05/19/16)

Information from the Southwest region of North Dakota

Temperatures in the region dropped below freezing towards the end of last week. According to NDAWN Hettinger reached down to 24 °F on May 14th and further north it ranged from 25-31 °F as a low. With these low temperatures it is important to scout fields for potential frost damage. The extent of frost damage depends on factors such as the growth stage of the crop, soil moisture content, and the length of time the temperature is below freezing. Where the old vegetation may look frost damaged, it is important to consider where the nodes and growing point of the plant are located. After a frost be sure to wait 4 days to a week to make a decision. If the growing point is not damaged and the new growth looks healthy there is a good chance the crop will survive.

Many growers in the region have small grains, pulses, and canola in the ground. In Hettinger County growers are close to finishing corn and flax with sunflowers next in line to be planted. In Stark County corn is about 50% planted with most not having started on sunflower yet. Alfalfa in the region is looking good, however some fields may have suffered from frost.
