We’re not Iowa (09/10/15)

I think many consultants and growers understand that just because we grow corn and soybeans we are not Iowa, but some appear to be confused. There are two important differences that I need to stress for those who think the capital of North Dakota is Des Moines, and both are related.

Strip-till (08/13/15)

To make strip-till practical in the Valley, follow the combine with the strip-till machine. Fertilizer P and K can be applied, and wait until at least the 1st of October to apply fall ammonia, and only then when soil temperatures taken between 6-8AM fall to 50 degrees F.

A Look Back at Side-Dress (08/13/15)

It is satisfying to see side-dress become more common in ND on soils with a high susceptibility to in-season N loss from leaching or denitrification. As plans are made this winter on strategies for next season, please consider the following:

Correct Crop Nutritional Diagnosis Using Plant Analysis (06/25/15)

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.

The Sources of the Annual Legume Previous Crop N Credit (06/11/15)

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.

Corn Yellowing Update (06/11/15)

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.

Soil Sealing, Crusting, Water Erosion and General Poor Soil Health (06/11/15)

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.

No-Till Fields Planted (06/04/15)

I have, or will have, 30 sites this year from Casselton to Beach to Bottineau in various studies.

Tillage- The ‘Gift’ that Keeps on Taking (06/04/15)

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.

Patience on Yellow Corn, but React to Yellow Wheat Now (06/04/15)

Most wheat fields are in the 3-5 leaf stage and have some yellow in them, especially in areas receiving near record May rains.
