What If It’s Dry at Planting?

March 8, 2012

 

We don’t often have dry soils at planting time, but this year, it looks likely.

 
By Roger Elmore, Iowa State University Department of Agronomy
 
Dry conditions persist in many parts of Iowa and the Midwest. Elwynn Taylor, Iowa State University Extension and Outreach climatologist, indicates there is some probability that these dry conditions will persist.
 
Here’s a three-part series that identifies a few key issues to keep in mind when planting corn into dry soils. Click the questions to read the answers.
 
…………………………………………………
 
Some corn growing areas of the U.S. normally are not so blessed with good soils and precipitation at planting. Corn farmers in those areas sometimes use early-maturing hybrids to help mitigate drought conditions.
 
 
…………………………………………………
 
In areas of the Corn Belt with poorer soils and/or reduced rainfall, farmers typically reduce plant populations to compensate for the conditions. Is that something we should consider in Iowa if conditions remain dry at planting?

Should you consider lower plant populations?
