Cheap Garden Soil Amendment: Free Phosphorus From Fire Extinguishers

No, I'm not suggesting you go out and douse your plants with a fire extinguisher, but old and expired fire extinguishers do contain powdered phosphorus, which can be put directly into your soil.

To find this powder, contact a fire station or look in the phone book for companies who refurbish fire extinguishers--they remove the old powder and replace it with new, and can use places to put the old powder. I've got a composter that could use a good dosing for next year's dirt.

A typical extinguisher doesn't hold enough powder to make any bombs, so tough luck to any readers who might have terrorism on their minds.
