This will be great, as long as you don't till everything in the carbon won't bind up all the nitrogen. If pee on it as much as you can before you plant, you will get a nice bost of nitrogen to help break everything down. Keep adding more material on top throughout the season too. Build up as much organic material as you can. If you want, get some composted manure and add a couple scoops to the hole when planting the veggies.
