Hello again.
He does not have the PF mod.
It was on field 9 he had the issue.
He used the Bredal spreader that you start with on new farmer and one from Kverneland (bought). Both failed.
The fertilizer sprayed out of the spreaders, but the field didn't show the stage process. The soil did not change color either.
He tried it before and after seeding. The lime worked like normal.
Field 10, that worked as normal.
