Neudorff pH soil test

Absolutely ideal tool when it comes to set an optimum pH in the soil. The test is simple and the manual shows how soil samples for specific areas (eg farmland, lawn, etc ...) are to be taken. Unfortunately the bottle of distilled / deionized water is somewhat small - the amount of liquid is sufficient for the tests, but are rinsed test tubes also with demineralized water after testing, to prevent distortion of subsequent test results. But since it is only a rather crude method, this point is probably not as important. However, accuracy is sufficient - which lie between the indication stages in shades, you can still estimate well!
From me therefore 5 star - to encourage anyone who wants to pay attention to soil health in his garden.
