Rapitest 1602 Soil Test Kit for Garden, Vegetable, Flower, and Lawn USA designed and assembled the soil tester completely, quickly and accurately measures/analyzes the soil pH acidity and garden

I agree with the other reviewers. I thought that I could do all 4 tests 20 times, but the tablets are enough for each test 5 times.It was easy to use, a little messy and for NPK, you need to brew your soil in water, shake well and let settle for up to 24 hours.I haven't had my soil tested through the ag extension office, so hard to know if the tests are close to accurate or accurate. But now that I'm a little more mature gardener, I need to be doing a better job of giving my flowers the nutrients they need.

I was very keen on using this test to test my soil here in Australia.Unfortunately only the K one triggered a result. Tried it twice (once with really cloudy and once with less cloudy water.)I find it hard to believe that my luscious well maintained and well fertilised lawn is completely devoid of N+P.

Test kit works well and you have 5 days of testing during the growing season

Excellent wee kit very easy to use with distilled water and hopefully should give my garden a bit of an edge
