Seepwater Damaged Crops

It seems appropriate to follow yesterday's blog with pictures of crops damaged by seepwater near  Portage Des Sioux, MO.  The seepage controls mentioned yesterday are meant to preserve the integrity of the levee.  They do not keep seepwater out.  These are large fields and only shows part of the damage.  There are very good crops in the same field, but how do you make up for large areas of zero yield.
