Iowa’s wet spring and cool temperatures not only slowed planting progress but also slowed Growing Degree Day accumulations. These factors contributed to yellow corn plants across the state as well as within-row variability in plant to plant growth and development. Seedling diseases reduced stands.
Producers with soybean fields that have dampening-off can contribute to the ongoing study of seedling diseases to identify oomycete pathogens.
Continued wet soils in some parts of Iowa are raising nitrogen loss questions that are answered with an understanding of biological processes important to potential N loss.

The storms last Sunday, May 25, and again on the May 29 and 30 have unloaded extraordinary amounts of rain in many parts of Iowa. Soils in the majority of the state are likely saturated. Low lying areas of fields whether they are tiled or not, are covered with ponds and areas along streams and rivers are flooded. It is not an attractive sight for producers!
