Growers and crop consultants in the Valley are well acquainted with iron deficiency chlorosis (IDC) through years of experience.
I have already referred to plant analysis as a tool that growers/crop consultants can use to better diagnose nutritional problems suspected from symptoms observed in the field.
Spring wheat and durum is approaching heading. My plots near Lisbon are in the boot stage and will head out in a few days.
Many more growers are planning to sidedress corn this year than in the past. Most growers that have tried sidedressing the past few years have been successful at increasing corn yield over fields with preplant only.
Traveling around the eastern part of the state almost half of the corn fields show some signs of S deficiency.
I meant to write this later, but I have stimulated so much conjecture that it was time to write this. Those of you that attended the Advanced Crop Advisor workshop about 10 years ago where Dr. Bundy at University of Wisconsin was speaking already should know this, but perhaps you have forgotten.
Most fields with corn have begun to green up with much warmer temperatures. There are some areas, particularly in medium to sandy soils on ridges/slopes that have begun to show signs of N or S deficiency.
The effects of too much tillage are again seen in the state with stark evidence of gullies, rill erosion, surface crusting, sealing of soil over trying-to-emerge germinating seedlings, and flooded field areas.
I have, or will have, 30 sites this year from Casselton to Beach to Bottineau in various studies.
We do not see the dust clouds in fields this first week of June as we did in April, but soil is moving just the same.
Most wheat fields are in the 3-5 leaf stage and have some yellow in them, especially in areas receiving near record May rains.
The small grains in the RRV are generally green right now. However, in a trip yesterday in south central ND to put out a research plot, there were a considerable number of fields with yellowing in small grains.
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.
