Stress and the 2024 corn and soybean crops

As high temperatures continue and rainfall remains scarce, many Illinois producers are getting concerned about prospects for the 2024 crops. While it is not very productive to ask ourselves if we should have managed tillage and planting differently, remembering how this year’s crop is faring might inform some of our decisions in the future…

The 2023 corn crop as the season winds down

Rainfall in late June and early July brought relief from very dry conditions, but soils dried out again before August 5-9 rains over most of Illinois recharged soil moisture enough to restore crop prospects for the 2023 season. The August 15 U.S. drought monitor map showed 28% of Illinois to have no drought, 57% to be abnormally dry, and 14% to be in moderate drought…

Rainfall may not completely reverse the effects of drought

Nearly all of Illinois received rainfall in the late June and early July, with amounts of 2 to 5 inches across a large part of the state (Figure 1). There is more variability than the map shows – for example, only 1.67 inches fell at Willard Airport near Champaign, not the 2.5-3” indicated on the map. But there is no doubt that the rain boosted crop prospects for 2023, and reversed the month-long decline in crop condition…

Thinking about crop emergence

y 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…

Early-season soybean management in 2023

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….
