Storms hit eastern Iowa yesterday, bringing variable amounts of rainfall and enough wind to blow some corn down. The damage seems to extend across multiple counties, but I witnessed many fields with varying amounts of damage in Linn and Jones counties.

I received one report of a cereal rye control failure this week as temperatures warmed and rye growth resumed. Some follow-up questions and photos showed that concerns regarding burndown applications during cool, early-spring conditions have merit.

It seems that anhydrous ammonia (AA) applications and planting may fall very close together on the timeline of events this spring. This could be concerning with drying soils and lack of significant rainfall chances in the near future.

Last fall, I collected common milkweed (Asclepias syriaca) seed to establish some plots on a farmer cooperator's land over the winter. My plan was to seed directly into a standing cool-season grass adjacent to a crop field and determine the effectiveness of this method for plant...
