Due to large rain events this spring, many fields have been flooded.
While both corn and soybeans can survive flooding/ponding for a period of time, several factors determine the length of time plants can survive. Young corn plants can usually survive two to four days in flooded conditions. Death of corn plants is more likely prior to the V6 stage of development because the growing point is still below the soil surface.
Soybeans can usually survive two to four days completely submersed. If weather is cool (mid 60s or cooler) plants are more likely to survive several days of flooding. If temperatures are warm (mid 70s or warmer) plants may not survive 24 hours under flooded conditions. Ponding of six or more days can result in significant stand losses and death of all plants where ponding has occurred. Although ponding/flooding has the potential to impact stands, crops have the ability to survive under the right conditions.
