How might soybean yield be affected by hail damage?

  • June 24, 2016

In the early morning hours on Wednesday, June 22 a severe storm moved through western Illinois affecting crops throughout much of Henderson, Warren and Mercer Counties, including those at the University of Illinois’ Northwestern Illinois Agricultural Research and Demonstration Center in Monmouth.  Preliminary data collected by instruments maintained by the Illinois Climate Network at the center had the wind gusting to 78.1 mph and more than 1 inch of rain falling in a 10 minute period contributing to the nightly total of 3.34 inches.…

Storm Damage in Corn

  • June 23, 2016

High winds hit parts of central and north-central Illinois on June 22 and 23, flattening corn that was at stages V10 to V13 or so (4 to 7 feet tall.) Hail damaged leaf area in some places as well, but hail was not as widespread as wind damage.
Figure 1 shows corn completely flattened at our Monmouth Research & Education Center, following wind gusts up to 78 mph between 2:45 and 3:00 AM on June 22.…

Does the Corn Crop Need More Nitrogen?

  • June 13, 2016

Except for some areas of southeastern Illinois, the 2016 corn crop went in well, and on June 12 was rated at 75% good or excellent. Warm temperatures have speeded up growth, and although below-normal rainfall, especially in western Illinois, is starting to cause some concern, the 2016 corn crop is off to a very good start.
The corn crop this year has excellent stands and there are few drowned-out areas, though there is some unevenness depending on when the crop was planted and how much rain it received after planting.…

Update on Soil Nitrogen

  • May 6, 2016

Corn planting has moved ahead of the 5-year average, with 66% of the Illinois crop planted by May 1. Early planting usually means an early start to nitrogen uptake. But N uptake is slow for a month or more after planting: in one study we did in 2015, plants at the 4-leaf stage about five weeks after planting had only 4 pounds of N per acre in the above-ground part of the plant. So there’s time both to get N applied to the crop before it needs it and also time for N in the soil to move out of the rooting zone if it’s in the nitrate form and the weather turns wet.…

Rust pathogens are obligate parasites, meaning that they need a living host in order to survive. Wind and rain systems from further south bring spores to our area. This is why rust sightings in states to the South can help us in Illinois anticipate its arrival.…

Spring Nitrogen Management for Corn

  • April 18, 2016

Even though the price of nitrogen fertilizer has dropped some in the past year, the lower price of corn means that decisions about N management need to be made carefully, with an eye towards maximizing the return to this critically important input.
The return of dry weather over the past week and the forecast for the coming week has lessened the concern about N loss, though we still need to consider the possibility that some fall-applied anhydrous ammonia might have moved out of the upper part of the soil.…

Is Fall-Applied Nitrogen Still Present?

  • April 8, 2016

The pattern of warmer and wetter than usual weather this past winter has changed some in the past two months, but hopes for a warm, dry, early spring have faded as well. Concerns remain about how much fall-applied N might have been lost and about whether and how this should change how we manage N this spring.
Most Illinois producers waited until soil temperatures had dropped to 50 degrees or less before applying anhydrous ammonia last fall.…
