I tilled into the pumpkin patch 1 1/2 yards of compost, 6 bails of sphagnum peat moss, 100 pounds of alfalfa pellets, 30 pounds of gypsum and 20 pounds of granular humic acid. I then racked in a cover crop of winter rye that I will let grow all winter and then will till into the ground in the spring. In the spring I'll send in a soil sample and probably add another yard or so of compost along with what other items I need to make sure everything is adjust properly.
I'm guessing next season will be first season in this patch that I'll finally have my potassium and potash low enough that things will be balanced. That is if I don't screw it up again.
