I'm merging a field of old CRP (3 acres) with the remaining field (152 acres). I understand how to merge the fields, but the border line between the 2 fields doesn't disappear and maybe it isn't suppose to. I've read previous discussions about the procedure on how to remove the gap at the borders by using the include polygon tool, but I still have the red border (my color choice) showing. The 2 border lines are now just 1 border line and it is visible on both the field boundary and crop enterprise maps going forward in time. The editing was performed on the field boundary layer and not the crop enterprise layer since that is where the split occurs. I have version 2014.3.18. I know that this subject has been discussed more than the weather, but the previous posts didn't completely address my issue.
