Crushing oyster shells for the soil using simple tools

Oyster shells are loaded with useful minerals, but are often thrown into the garbage, an example of local resources that can be used to feed the soil and plants. Vinegar may be used to make a broad spectrum mineral amendment that can be applied to plants as a foliar spray. (   • How to Make Vinegar Extractions from ...  ) The shells may also be crushed using simple tools and applied directly to the soil for a longer term mineral amendment strategy. This process may be applied to other types of shells or bones as well, closing waste gaps, nurturing the soil to grow healthier plants.
