Considerations after Crusted Soybean
June 14, 2019
Soil crusting is challenging soybean emergence, but is it enough to warrant replanting? Here are early steps to remediate crusting problems and factors to consider when considering replanting.
Strategies with Delayed Soybean Planting
May 24, 2024
Adjusting soybean planting practices (row spacing, seeding rate and the use of custom planting) and relative maturity of the variety can help maximize yield potential when planting after mid-June.

Still planting corn and wanting to change to a different hybrid maturity? Here are some things to consider and a tool that can help you assess which hybrid options are likely to mature before an average fall freeze date for your location.
Study Highlights Motivations and Impact of Participating in an On-Farm Research Network
May 31, 2019
Forty Nebraska growers participating in the On-Farm Research Network recently shared why they conduct on-farm research and what it's meant to be part of a group of researchers. The results, published in the Agronomy Journal, illustrate a range of benefits, including cost savings and economic gains.

The bright vibrant greens of typical V2 to V3 seedlings are replaced with sickly yellows, indicating plummeting chlorophyll readings and photosynthesis. Roots of these oxygen-starved plants are no longer growing and are likely dying. The soil to which they are anchored has changed dramatically and full plant recovery is likely not possible.

Corn Establishment and Growth in Saturated Soils: A Brief Review of New Research
May 31, 2019
How long can seedling corn survive under flooded conditions? A review of current scientific literature offers new understandings of when and how plant injury occurs and what factors affect it.
Interseeding Cover Crops into Corn or Soybean
May 23, 2019
In some years it may be difficult to well establish a cover crop after corn harvest. This article surveys current research on interseeding into an established crop, further considerations, and how to test this practice on your farm.

The west half also is covered with a November 17 planted cereal rye cover crop. Soil temperatures 2 inches deep were recorded in each half, but were essentially the same, so are averaged in this report. Figure 1.

Soybean Germination/Emergence with April Planting Dates Relative to Coincident Air and Soil Temperatures in April and May
May 16, 2019
A closer look at air and soil temperatures in April and soybean germination and emergence from 10 planting dates did not find chilling injury, despite periods below 50°F. Further research is needed to better understand the imbibitional period in soybean.
With Delayed Corn Planting, Is It Time To Switch Maturities?
May 9, 2019
Research suggests that staying with a full-season hybrid until late May often provides the best yield. If planting is delayed to late May or early June, consider a medium-season CRM might be considered.
