The 2021 Illinois soybean crop was planted relatively early, with the 50%-planted date of May 5, more than two weeks ahead of normal. As in most recent years, some producers began planting soybeans before they started planting corn, although the first official record of soybeans planted (5% by April 19) was a week later than that for corn (5% by April 12). Planting conditions for soybeans were fair to good, but weather after planting was not consistently good.…

The 2021 corn crop was planted ahead of normal, although “normal” includes the very late planting in 2019 and late planting in 2020, so “typical” might better describe 2021 planting progress. There were no extended wet periods in April or May, but wide swings in temperatures affected emergence and early growth. Crop ratings are about average for mid-June, but have slipped some, probably due to dry conditions in some regions. June temperatures have been favorable for crop growth,…

Corn planting progress continues, with 23% of the Illinois crop planted by April 25, and planting continues with some rain delays the last week of April. The warm temperatures that finally arrived will be good for emergence of both corn and soybeans, but there are some reports of damage to early-planted soybeans from frost on April 21 and 22.
Warmer soil temperatures will start the mineralization process by which microbes release N from soil organic matter,…

Farmers in several states to our west (particularly in eastern Nebraska) have been dealing with the soybean gall midge for several years. We have been fortunate to avoid this new soybean pest so far in Illinois (a current distribution map, scouting instructions, and additional information are available at https://soybeangallmidge.org). We want to stay on top of soybean gall midge if it does arrive here,…
