When soybeans emerge, the successful crop producer will make sure to examine their fields and evaluate soybean stands to decide when and if to replant. This involves physically walking the fields and examining the emerging plants to assess growth and development, as well as taking stand counts.
From emergence to 3rd leaf stage is the time when farmers should be out in their fields assessing stands to determine if replanting is necessary. Replant decisions are never easy and are ultimately determined by which decision provides the greatest net income. Each field will have its own set of circumstances that will influence the decision. Remaining stand level and likely replant date will be the key issues.
As corn emerges, take time to evaluate corn stands. This involves taking stand counts and visually assessing seedlings to see growth and development appears normal. This can help alert us to potential issues that may due to planting, insects, diseases, and/or environmental conditions.

As of May 20, an estimated 27 percent of Iowa’s soybean crop is planted according to the USDA-NASS Iowa Crop Progress Report. Early-planted soybeans have been exposed to stressful conditions following multiple rainfall events, cold temperatures, and wide temperature swings in the last several weeks.
My area has a real range of conditions with corn planting 65-75% complete in the northwest part of my area. There is maybe 15% of the soybean crop planted in the northwest part of my area. The corn and soybean planting progress is 95%+ complete in the northeast part of my area.
Questions today are replant decisions and effects of the frost damage to corn.
The United States has almost half of the corn crop planted for the season at 45% complete, according to the United States Department of Agriculture (USDA) Crop Progress Report on May 2.
The USDA reported 57% of corn planted in Iowa as of May 1, with the 5-year average being 28%. The weekly report had 7% of corn emerging in Iowa, which is 4% ahead of the 5-year average.
The Crop Progress Report showed 7% of soybeans had been planted in Iowa as of May 1, 1% behind this time last year, but still leading the 5-year average by 4%.

The frequent rains that have soaked Iowa this year have left many corn and soybean fields unplanted or with flooded areas. Many producers are wondering what options they have under their multiple peril crop insurance (MPCI) policies.
Roger Elmore, ISU Extension corn specialist, discusses the things to consider when making the decision whether to replant corn or not. In the second crop minute this week, Erin Hodgson, ISU entomologist, encourages farmers with corn emerging to scout fields for black cutworm. Elmore refers to the table on page 12 in the Corn Field Guide for current relative yield potential of corn by planting date and population.
