Animal manures make for the best type of fertilizer for organic gardening. It needs to have been aged for at least 30 days to make the nitrogen more usable. The manure varies depending on the type of the animal, the way the animal was fed and even the condition of the animal. After letting the soil rest with the animal manure, you’re ready
to plant and grow the healthiest garden possible.
