In Az we had mostly clay soils.  Gypsum was used to
"loosen" the soil to increase water penetration.  I
never could find out if the the gypsum in drywall was
the same as agricultural.  In other words if you had
leftover drywall could you break it up and put it in
the soil or was the chemistry different than
agricultural gypsum?
