Impressive moth flights have not only kept the Illinois insect monitoring network cooperators busy, but neighboring states are reporting lots of black cutworm and true armyworm moth activity as well. The current forecast and planting progress has raised questions about the potential for these pests in the coming weeks.… Read more
April has been a little warmer and drier than average so far this year, which has allowed a good start to corn planting and some progress in soybean planting. This is expected to change, with above-normal rainfall and below-normal temperatures over the next 10 days or so, through the first week of May.… Read more
Decades ago it was very common for the majority of corn and soybean acres in Illinois to be treated with one or more soil-residual herbicides before crop/weed emergence. During the 1980s, commercialization of broad-spectrum, postemergence herbicides began the shift away from widespread use of soil-residual herbicides; products such as Basagran, Classic, Accent and Pursuit contributed to the early adoption of postemergence weed control programs. … Read more
Most corn producers have made plans on how to supply the 2017 Illinois corn crop with nitrogen. But with the stakes high, unusually early N application this past winter and early spring, the delay in fieldwork due to rainfall over the past week, and ongoing pressure to “get nitrogen right,” some might be rethinking plans as the season gets underway.… Read more
On Thursday, March 30 beginning at 9:00 AM, I will present a webinar summarizing our recent N management research, which is funded by the Illinois Nutrient Research and Education Council (NREC) using fertilizer checkoff funds.
Topics will include the status of N applied last fall, a summary of results from our N form and timing studies over the past three years, and a look at how well soil N tracked through the spring can tell us if we need more N.… Read more
Relatively dry weather in recent weeks throughout much of Illinois and an early start to fieldwork might provide the unusual opportunity this year of letting us choose corn and soybean planting dates instead of having to wait until it’s dry enough.… Read more
In January I posted about the large project we are part of, funded by the North Central Soybean Research using soybean checkoff funds, to gather information on some 500 soybean fields in Illinois for each crop year from 2014 through 2017.… Read more
Despite the snow falling outside of my window this morning, plans continue for the upcoming survey season. Mother Nature has hinted at spring with temperatures in the 70’s just last week and its time to start thinking about spring insect trapping.… Read more
The unseasonably warm and dry weather we have had during February this year has a lot of people applying ammonia, and others considering it. This raises the question of whether or not February is a good time to apply NH3, and also the question about whether or not a nitrification inhibitor (N-Serve) should be included in late-winter applications.… Read more
Soil fertility, crop production practices and environmental stewardship will be the foci of a Soil Fertility Seminar on February 28, 2017 in 18 different University of Illinois Extension county offices.
Presentations will be delivered through web conferencing from 9 a.m.… Read more
