Southwest ND (05/07/20)

Information from the Southwest region of North Dakota.

Wheat, canola, and pulses continue to be planted across the region. Some producers have started on corn and soybeans. There is a lot of fieldwork going on throughout the countryside, if it isn’t planting equipment going down the road, it’s a fertilizer spreader or sprayer. Moisture as always has been variable, some fields and portions of fields are still too wet to get into but a majority of the acres I’ve seen could use some moisture in the topsoil. Scattered showers and in some cases hail, fell across the region over the past week. According to NDAWN from April 27th to May 5th Dickinson received 0.16 inch of rain but some in the surrounding area received more. While much of the state is facing the issue of too much moisture there are many in this region that wouldn’t mind a bit more moisture, to a point. With cold weather in the forecast over the next week we’ll need to keep a close eye on early planted corn and particularly soybean stands.

As a reminder be sure to consider plants per acre when seeding, not just bushels/acre. When things get busy some decisions can be rushed, but be sure to think for the long term. When facing potential issues in a field be sure to follow the steps of integrated pest management: identify your issue, monitor and assess damage, follow guidelines for when management action is needed, do your best to prevent the issue in the first place, and finally use a combination of biological, cultural, mechanical, and chemical management tools. Along with potential issues like disease, or insects such as wireworm be sure to consider issues stemming from acidic soils. If you haven’t soiled sampled in a while and you’ve noticed areas with poor stand be sure to take a soil sample at a 0-2” and 2-6” depth and get it tested for pH in those zones. If the pH is below 5.5, application of lime is recommended. While the amount of lime needed will vary, you’ll likely need at least 1 ton of lime per acre in acidic zones. I know many are considering putting a few hundred pounds of lime in furrow, but the research I’ve read does not show that to be an ideal solution when you are dealing with acidic soil. We’ll be taking a look at in-furrow lime on a few trials this season. We have also expanded the acidic soil wheat variety trial this year. Changing the soil pH is not going to be a quick fix, there are tradeoffs involved with each management option. Be sure to stay aware and share the roads.
