Food For Everyone Foundation - FAQ -The Zoo-Doo Man: "However, the most important thing I learned in that two-year experiment was not how to make and sell Zoo-Doo. I learned for myself that I could grow better vegetables more consistently, and with a lot less time, cost, and hassle, with a few pounds of inexpensive natural mineral nutrients than I could with truckloads of 'the world's best compost.'

I therefore continue to use good, clean organic materials when they are available, but I know that highly productive vegetable gardens are not dependent on improving the soil with organic material."
