I mentioned in another thread that i would start a new thread on how to improve soil. While this is most applicable to garden soil where food is grown, it will improve any plant's health.

This thread is for providing information on the proven soil building methods pioneered by Albrecht, Reams, and Astera (who's website I am getting a lot of the info from). I will post a few interesting articles/quotes/etc. for your reading pleasure...
