LaMotte Soil Testing Kit

Soil Test kits allow you to learn more about how your garden grows. This particular kit lets you to test soil samples for concentrations of nitrogen, phosphorus, potassium, and soil pH. Once you have the results from the tests, you will know how to amend the soil, which can improve growing conditions for your plants.

LaMotte kits are widely available in slightly different configurations, but I got mine online from Territorial Seed Company. The kit includes several informative booklets on soil science.
