decent to good drainage for this area. 40 inches of rain. if bulk powerplant gypsum, 500#. if pelletized gypsum, maybe 200#? bulk is around $60 a ton by the time it gets spread maybe? or lets say $22 an acre (my thought was spread it in the fall or winter after corn going to beans and then bean crop use it and corn crop use it the next year with 5 gpa of side dress ats to supplement.)   pelletized gypsum i think i'm around $250-300 a ton maybe? idk to be honest yet.
