# Rain, heat increase risk of ponding | MU Extension

> University of Missouri Extension warned that predicted low-90s temperatures the week of May 8, combined with intense or recurrent rain, could cause ponding and flooding damage to corn and soybean seedlings. Soybeans tolerate flooding better than corn, and damage would include stand reduction and lower yields.

## Why it matters

Replanting or yield losses from waterlogged fields would reduce corn supply and support feed grain prices. The effect is localized to Missouri-area fields unless wetness spreads across the Corn Belt.
