I didn’t explain myself very well, here’s a better job:
“ A somewhat uncommon, but dramatic, stunted root symptom is one referred to as the “floppy corn” or “rootless corn” syndrome (Nielsen, 2019a). This problem occurs most commonly as a result of the detrimental effects of excessively dry surface soil near the time of initial nodal root elongation in young (V2 to V4) corn plants. Young nodal roots that emerge from the crown area of the plant will die if their root tips (and associated meristematic areas) desiccate prior to successful root establishment in moist soil. The crown of a young corn plant is typically located only 3/4 inch or so below the soil surface and so is particularly vulnerable to dry upper soil conditions.”
