Testing Soil Quality by Growing Radishes

Have you ever heard of the phrase "canary in a coalmine?” Coal miners used to take canaries into coal mines where they acted as early-warning signals for toxic gases or fumes. If the birds became sick, or died, miners would have  quality of the air they were breathing.  You can do something similar to test the quality of your garden’s soil by growing radishes. While growing radishes to test your garden soil will not give you any insight into toxins located in soil, this experiment can give you insight into what is lacking in your garden’s soil thus saving you time, money and a lot of heartache before you begin planting.
