The Rapitest Soil Tester includes 5 color coded sample tubes and a color comparison chart for analyzing the following (2 tests each – 10 total):
Nitrogen (N) – Directly responsible for healthy green leaves.
Phosphorous (P) – Vital for healthy root development.
Potassium/ Potash (K) – Essential for flower and fruit development.
pH – Controls how plants utilize the nitrogen, phosphorous and potash available to them. All plants have a pH preference, so it’s 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.
