Part of a row of corn struggling to survive
These plants, in a Clay County corn field, are in deep water and deep trouble! The bright vibrant greens of typical V2 to V3 seedlings are replaced with sickly yellows, indicating plummeting chlorophyll readings and photosynthesis. Roots of these oxygen-starved plants are no longer growing and are likely dying. The soil to which they are anchored has changed dramatically and full plant recovery is likely not possible.
