maturity

One of the pressing questions this fall is when corn will reach maturity and if there is going to be enough time to dry down in the field. We have developed and released a corn grain dry down calculator that can help determine how quickly corn grain moisture will dry down in the field. The calculator can be applied at any location across the Corn Belt, from North Dakota to Missouri and from Nebraska to Ohio. Users select a map location and then enter a date and a kernel moisture content at that date. In turn, the tool projects in-field corn dry down. This tool can be used to estimate when a specific field will reach appropriately moisture for mechanical harvest (15-20% moisture) based on user input. The tool allows scenario planning by entering estimated dates and grain moisture for crops that are yet to mature compared to fields where crops have already matured.

Prepare for a long harvest season.

Planting delays in Iowa last spring could prevent a significant portion of this year’s corn crop from maturing on time, said Iowa State University agriculture experts. That means farmers may still have corn to harvest deep into November as they attempt to give their corn fields as much time to dry down as possible.

An early freeze could stop a portion of the corn crop from reaching maturity, and farmers will watch temperatures closely in the coming weeks, the ISU experts said.
