The pH, N, P, K Soil Testing Kit is a comprehensive testing kit containing the necessary reagents to perform approximately 10 tests for each of the following nutrients:

pH - It is important to test the pH of your soil to ensure the acidity levels are correct for the plants you are growing. Each area that you intend to plant should be tested as the soil's pH may differ in various parts of your garden.

Nitrogen (N) - This is essential for the growth of vegetation especially grass and leafy plants. The correct amount allows for healthy growth, too much and the plant's structure will be damaged.

Phosphorus (P) - This nutrient is necessary for strong root growth and root vegetables. It helps with the formation of buds and healthy stems. A lack of phoshorous will stunt the growth of a plant.

Potassium/Potash (K) - This nutrient is important in the development of flowers and shrubs. The correct potassium levels ensure that flowers become more fragrant and have improved colour. In vegetables it ensures a better quality crop and also makes plants more resistant to disease.

The pH, N, P, K Soil Testing Kit comes complete with full instructions and contains enough reagents for approximately 40 tests (10 for each element).
