Soil Tester pH+N+P+K Tester

Test the acidity and nutrient content of your soil yourself. Various reasons to measure the acidity: sometimes unexplained growth inhibitors occur in the garden, should I spread lime or not? You want to create your new garden... which plants will thrive best? The acidity is the basis, followed by the humus content and the nutrients... The 3 most important minerals ("salts") that a plant uses are nitrogen N, phosphorus P and potash K (not to be confused with Calcium = lime). With this test kit you can test the content of these 3 nutrient salts. Good for a total of 60 tests.
