Striperon, technically correct re: wood chips and other high nitrogen sources. I would not till wood chips directly into the soil. But wood chips as a component of chicken litter, in my mind are a perfect blend of high carbon and high nitrogen. With the exception of grass clippings, all of the mulch materials I use are high carbon. I am not a soil scientist, oh how I wish I were! But, here's my take from years of experimenting, working with deep mulch, and spending hours watching and observing the interaction of plants with various gardening techniques: A mulch, whether it is high carbon or not so much, sits on top of the soil where there is an abundance of oxygen. The soil microbes (as well as the larger creatures that assist with nutrient break down) thrive at the soil/mulch interface, and usually the moisture content is ideal. So, in my garden this spring, I will definitely be using my special wood chip/chicken poo blend as a mulch. I also intend to do a modified very small chicken litter hugelkulture experiment. If you really want a mind bender re: high carbon sources robbing the nitrogen from growing crops, do some research on this topic. If nothing else, it will convince you that just because someone says something should be done a certain way, don't make it so. When I hear that something must be done a certain way, my mouth automatically says, "but why?!" Further evidence to refute the whole nitrogen robbing issue: Why is the soil life so very abundant under a log, a pile of wet newspaper, or a good layer of cardboard? (All of which are high carbon "nitrogen robbers".) And why is the hugelkulture concept so popular, and apparently working so well? Food for thought, and I can't wait to get into the soil and start working out some answers.
Bucka, your experience with wood chips not proving detrimental to gardens reflects my experience.
