Iowa farmers are catching up with planting corn and soybeans despite just three days suitable for fieldwork last week. Iowa Secretary of Agriculture Mike Naig said in this week's crop report 40 percent of corn acres and 11 percent of soybean acres are planted. That puts corn planting three days behind normal and soybeans on pace with the five-year average. Problems persist in northern Iowa where wet conditions mean less than 10 percent of corn is in the ground and no soybeans are planted.
