Corn N Sidedress Options (06/18/15)

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.

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.

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.

Early spring yellowing in small grains (05/28/15)

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.

Rivers to Nowhere (05/21/15)

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.

Sulfur Losses in Rainfall (05/21/15)

The high rainfall over the past week has resulted in S losses, particularly in sandier soils, especially on hilltops and slopes.

Nitrogen Supplements (05/21/15)

There are three reasons why growers might need to consider supplemental N fertilizer a little later on in the growing season.

Soil Temperature and Germination of Sugarbeet Seeds (05/07/15)

Sugarbeet seeds germinate and emerge over a wide temperature range in the presence of adequate moisture and oxygen.

Wake Up Call (05/07/15)

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.

Deep Sampling for Sugar Beet (09/11/14)

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.

Fall Soil Sampling (09/11/14)

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.

Prevent Planted Acres in 2014 Ripe for Prevent Planting in 2015 (08/14/14)

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.
