Now is a good time before bustling back to the field to drive around the fields and look, and take pictures and make notes of ditches that go nowhere.
The high rainfall over the past week has resulted in S losses, particularly in sandier soils, especially on hilltops and slopes.
There are three reasons why growers might need to consider supplemental N fertilizer a little later on in the growing season.
Sugarbeet seeds germinate and emerge over a wide temperature range in the presence of adequate moisture and oxygen.
This winter, we had the unhappy reminder that we live in a very windy place. The Fargo radio was abuzz with calls about ‘black snow’ and some suggested that it was from oil-field flaring.
Here are my recommendations for North Dakota N application.
If you are a sugar beet grower (tough year, eh?) and your consultant still has a working 4 foot soil sampler, by all means have them use it.
Years ago, there was a formula that NDSU published that offered an adjustment for nitrate levels in soil samples obtained before the end of September.
This spring, there were several growers that mentioned to us that the only prevent plant acres from 2013 that they could plant in 2014 were those that were seeded to a cover crop in 2013.
Conventional wisdom is that strip-till can’t work in the Valley because of our high clay soils. I know that this is untrue.
During the 2010, 2011, and 2013 I estimated N losses in high clay soils based on my ongoing corn N rate project ranging from about 100 pounds per acre in 2010 to nearly 150 pounds per acre in 2011 and 80-100 pounds per acre in 2013. This spring, I established two multi-treatment corn N rate/side-dress N rate studies.
The 2nd Annual Soil Health Field Day will be held on August 21 in Mooreton, ND. This year, we will feature some of the primary topics from the Crop and Pest Report, including but not limited to, using cover crops effectively, tools for salinity management, whole systems approaches for management and erosion control.
The new North Dakota Corn Nitrogen Calculator was posted on my web site in late April. Now, the companion Corn Fertility circular is available on my web site and on the NDSU Extension web pages.
Read about Late N application options in spring wheat/durum and corn.
Many spring wheat fields are approaching heading. The weather has been wet and cool, and the prospect for high yield, if the fields escape fusarium head blight, is good.
Several tools exist for preventing or reducing iron deficiency chlorosis (IDC) in soybeans. The most important is the selection of a variety with a high level of resistance to this disorder.
On my way to and from Devils Lake today, nearly every field of soybean had symptoms of iron deficiency chlorosis (IDC). Therefore, a short review is in order.
I have stated at many meetings that the high clay soils in the Red River Valley are high enough in organic matter and have a high enough sulfatic water table that sulfur fertilization is not needed. However...
The row crops in our region look as poor now as in 2011, our last perpetually wet spring.
With prevented planting (PP) more common throughout North Dakota, using cover crops to prepare the land for next year is a desirable option.
