Very cool seeing someone else on HN take on restoring their backyard soil. I've been at it for two years in my quarter acre plot and the results are starting to show, so keep at it! Very interested in your bootcamp link so thanks for posting that.

Personal tangent: The property I have was a typical Roundup maintained monoculture lawn without any insect diversity, bees, etc. Now it's teeming with all types of insects and different native species that have re-established themselves and I've been able to use about half of the property for fruit and vegetable production. It's awesome to see the progress that's possible even in such a short time.
