Corn and soybean survival in waterlogged soils
He adds that on-farm research and observations also say not to give up hope as soybean plants at the V2-V3 growth stage can survive on soils flooded up to eight days.
"If enough plants survive the temporary soggy conditions, yields in depressional areas can be equal to or better than upland areas during dry summers," Mueller said.
Soybean yield reductions from 0 to 100 percent can occur from three days of flooding at the V2 to V3 stage compared to adjacent non-flooded areas. However, he says low plant populations and shorter plants resulting from ponding/flooding often result in decreased yield. The probability of yield loss increases as final soybean plant population decreases below 100,000 plants/acre.
For growers needing to replant acres lost due to flooding, Mueller says there should be plenty of seed available in the maturity range they need, but they won't have the luxury being picky in their hybrid or variety selection.
