You test the soils in each type to see how diet affects both the earthworm population and the nutrients they put back into the soil. A soil test is a chemical analysis that estimates a soil's ability to supply nutrients. We teach how to collect samples to test as well as how to interpret and evaluate the results. The quantity of available nutrients in the sample determines the amount of fertilizer that is recommended. You can buy the most attractive plants in the greenhouse or order the best seeds, but they won't produce the best results if the soil lacks the proper nutrition or the proper qualities the soil .
