A simple soil test with accurate results! For a healthy and productive garden, it’s important to know your soil. The availability of soil nutrients (like Nitrogen, Phosphorus, and Potash) to plants depends on the soil pH they are growing in. This soil test kit allows you to identify any deficiencies so that you can confidently amend and fertilize as needed. Avoid over- or under-feeding your plants! Use specially designed color comparators to test soil pH and nutrient levels in your garden soil. Includes a chart of pH and NPK levels for more than 100 plants, instructions for amending soil conditions, and a total of 40 tests: 10 each for pH, Nitrogen, Phosphorus, and Potash — complete with 4 removable film color charts, 4 color-coded tops, and color-coded capsules.
