By April 16, 10 percent of the Illinois corn crop and 4 percent of soybeans had been planted. Rainfall across Illinois is below normal so far in April, with an unprecedented 10 (of 20) days with no rainfall recorded anywhere in the state. Topsoil moisture ranges from slightly above to slightly below normal across Illinois; there are no areas of really wet or of really dry soils. Some rain fell over the last 24 hours, but little rain is forecast for the next week.…

Hundreds of full-rate N trials run over the past decade in Illinois have been used to develop the N rate calculator that generates Maximum Return to Nitrogen (MRTN) N rates. While using the MRTN rate maximizes the dollar return to N, it is a lower N rate than many producers use currently. Reluctance to lower rates following years of high yields with high N rates is understandable, given that the yield-goal-based N rates used into the early 2000s called for raising N rates as yields increased.…

March was a wet month across much of Illinois. Statewide precipitation averaged 4.48 inches, 1.27 inches above normal. The wet trend continued throughout the first week of April, especially in northern Illinois: more than 1.5 inches of rain fell in some places. NASS reported 1.7 and 2.5 days suitable for fieldwork for the weeks ending April 2 and April 9, respectively.
March temperature averaged 40.5 degrees compared to the 30-yr average of 41.1 degrees, but with wild swings.…

March rainfall ranged from about normal to an inch above normal in the northern half of Illinois to twice normal in the southern end of the state. NASS reported 1.7 days suitable for fieldwork for the week ending on April 2, and soil moisture is rated as adequate or surplus in more than 95% of the state. Up to an inch of rain fell in the first week of April, but dry weather is in the forecast,…

Illinois producers planted 650,000 acres of winter wheat in the fall of 2021 and harvested 560,000 acres in 2022, with an average yield of 79 bushels per acre. Boosted by high world wheat prices, high wheat and good doublecrop soybean yields, and dry fall weather, planted acreage for 2023 rose to 880,000 acres. That’s 45 percent higher than the average of the past ten years, and the highest planted wheat acreage in Illinois since 2008. Crop condition ratings on March 26 were good,…

As in past years, our Moth Trapping Network is set to begin April 1 with our spring migratory insects. We are currently looking for cooperators to monitor both black cutworm and true armyworm traps from April 1 – May 31.

Requirements for trapping:

• Set up traps provided.
• Check traps regularly. Ideally, we’d like traps to be checked every other day to help accurately identify significant moth flights, but checking on Monday,
