Rapitech STK008 Soil Test Kit for measuring pH and NPK (80 tests)
Test your soil for a healthy garden! To test the soil in garden beds where you will plant shrubs, perennials, vegetables or fruit, dig down 10 cm with a trowel and take a small sample at that level. For lawns, annuals and houseplants, take a sample 5 – 8 cm below the soil surface. Easy system to prepare your soil samples. Compare your test results for pH, N (Nitrogen), P (Phosphorus) and K (Potassium) individually with the included color reading chart. In total 4X 20 tests. English manual and pH preference list included.
