Planting occurred at a near record pace in much of Iowa due to lack of rain in late April. This string of dry weather also allowed most herbicide applications to be made in a timely fashion, but now there is concern about herbicide performance after prolonged time on the soil surface.

Farmers in Iowa have been experimenting with very early soybean planting dates, from late March to mid-April. Based on reviews of the yield data, there is not a consistent yield benefit to planting early as opposed to planting the first week of May. But one benefit of very early planting is that...

The monarch butterfly (Danaus plexippus) population east of the Rocky Mountains has declined for many reasons, but loss of milkweed (Asclepias spp.), its’ larval host plant, in the U.S. Midwest, is a contributing factor. To help increase the monarch population, an estimated 1.6...

March into early April has been warm enough and dry enough to the point that soil conditions are good for planting. The calendar date is a bit early; after all the crop insurance, replanting is April 11. Regardless, many are pondering if they should be planting corn already, and some maybe...

In 2019 Iowa had over 460,000 prevented plant acres. As we prepare for the 2020 growing season, one concern we sometimes hear about with prevented plant acres is fallow syndrome. Fallow syndrome happens when the populations of “good fungi” known as vesicular-arbuscular mycorrhizae (VAM) are...

This year let’s all toss out planting windows for corn. Farmers should be focused on when soil conditions are prime to plant. Soil temperatures need to be on the rise; 50oF and rising. Planting 24-36 hours before a cold spell—regardless of how long—is putting your seed at risk of cold...
