Use this Digital Soil Test Kit to assess the quality of your garden soil. Performs 25 tests: 10 for pH levels and 5 each for primary soil nutrients: Nitrogen, Phosphorus and Potassium (N-P-K). Read more Utilizing advanced LED digital technology and optical calibration systems, this Digital Soil Test Kit quickly tests soil samples measuring levels of pH, Nitrogen, Phosphorus and Potash. This kit uses an optical soil test chamber to recognize the color hue specific to your soil's pH and nutrient levels. The tests are performed in four color-coded test tubes, one each for pH, Nitrogen, Phosphorous, and Potassium (Potash). The testing reagent capsules for each test are color coded to match the tube caps. A dropper is provided to facilitate transferring the test solution into test tubes. The kit also contains a convenient test tube holder or dock, which will hold all four test tubes while the color is developing. Once you have your soil test results, the instruction booklet tells you how to adjust soil pH and provides recommendations for fertilizers. The booklet’s pH preference list allows you to select plants for your soil’s pH or know how much to adjust the soil pH for your plants. Batteries included. This unit will operate for approximately 1,000-1,200 tests per battery set. Replacement batteries: (3) #357 silver oxide, 1.55 volt.
