Cedar Rapids Gazette: For Iowa farmers, the planting season pain is real with no relief in sight. It has been a wet, cool May so far in Iowa, and that has had a detrimental impact as farmers try to get their corn and soybeans in the ground. Iowa corn growers had 70% of their expected crop planted as of May 19, the most recent data available from the federal agriculture department shows. But that is more than a week behind the five-year average and the lowest percentage of the crop planted by that point in 24 years. Planting of the state’s soybean crop also is more than a week behind the five-year average.
