Egg shells are a great idea, if one eats eggs. Breakdown is fairly rapid in organic gardening terms.
Although Calcium Citrate meets the requirements for Certified Organic (USDA NOP), many people who garden by the organic philosophy will not accept it because the compound sold agriculturally is entirely man-made.

Calcium citrate can be made from combining a natural and accepted lime source (limestone or egg shells) with common vinegar. A liquid version is readily useable.
I didn't realize that we were talking about 100% mulch. I thought that I read that the leaf mulch was being used to top dress his garden plot.
Also, for those who don't eat eggs, I have found that local restaurants will often gladly set them aside. You can easily gett 100 or more a day in such a way.
