This is a straight forward manual on how to maximize your garden's potential without pesticides or store bought fertilizers. Additionally, there are many factoids on the "old fashioned" methods of gardening that were learned by trial and error over the history of humans.
It's a great source for "use what you have" gardening. For some things, like insect control, there can be more than one or two solutions depending on your area and what you're growing.
A handy guide for the beginner or intermediate gardener.
