Southwest ND (6/04/20)

Information from the Southwest region of North Dakota.

Topsoil is still very dry for many, including here at the Dickinson REC. According to NDAWN from May 1st to June 1st Dickinson received 1.28 inch of rain, Hettinger 0.48 inch, and Mott with 0.27 inch. Most wheat I’ve seen is tillering and early planted wheat is beginning stem elongation. Our soybean trial in Lefor, ND planted on May 18th is just emerging and was in the VE to VC stage on June 1st. Flea beetles are again very active in canola fields, cover crops, and gardens. Over this past week we wrapped up planting crop trials at the Dickinson REC with a hemp variety trial, teff trial, and cover crop demonstration.

This year we are testing 16 HRSW varieties for our acidic soil variety trial. With areas facing soil pH below 5.5, symptoms of aluminum toxicity should be showing stunted chlorotic plants and canola should be showing manganese toxicity symptoms (curled leaves with yellowing around edges). If you think this may be an issue in your field, again remember to sample from 0-2 and 2-6 inches for soil pH and if pH is below 5.5 plan for an application of lime. We are planning multiple programs on soil acidity in SW ND for this summer and I will keep you posted as planning progresses.
