Compost for the Pumpkin Patch

Today I picked up 2.5 yards of compost and put down two nice piles into the patch mixed with some shreaded leaves from the yard and grass clippings from the neighbor.  I hope to till these in next month.  In the spring I'll put in another 2.5 to 4 yards.  I'd like to see my organic matter come up another 3% by planting time next year.  The compost that I got today wasn't fully composted but was very nice horse manure with a lot of alfalfa in it.  Should be ready in another 1.5 months.
