Rapitest Soil Tester-5 color coded test tubes and a color comparison chart to test your soil for pH, nitrogen, phosphorus, and potash. Plants use Nitrogen, Phosphorus and Potash (N, P and K for short) for healthy growth. Nitrogen is directly responsible for healthy green leaves. Phosphorus is vital for healthy root development. Potash is essential for flower and fruit development. Plants also require the correct pH level (the relative amount of hydrogen in a substance) to control how they utilize the Nitrogen, Phosphorus and Potash available to them. All plants have a pH preference, so it is important to know the pH level of your soil. You can then choose plants with the same pH preference, or change the pH to meet the requirements of the plants in your garden.
