I have an area of my yard that had a lot of woodchips on it. I've removed as much as I could, but there are still a bunch of half decomposed chips mixed with soil. I would like to plant here, but I'm concerned that the woodchips will leach nitrogen from the soil as the decomp further. Is there something I can put down that will either speed up the decomp or help to restore niitrogen for planting in the spring (or both)

Thanks in advance!
