My Grandddaddy never harvested everything from his fields. whether it was cotton, Apples,grapes,Wheat or sweet taters he always left the corners and outside rows. Said it was for those who had less then we did. After all he had 800 acres that would irragate from the pecos and a bunch of kids(22) and grandkids to help out so he had more than he needed. He would also load up some produce. meat (we butchered our own) or wheat and take to anyone he heard of that didn't have enough. He said that is why he had plenty because he shared with those who had little or nothing.
