Luster Leaf 1602 Soil Kit, 20 Tests

Perfect easy testing

Lieferung wie verschprochen. Artikel wie beschrieben.

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.

Very easy to use & reliable results as compared to a professional university extension office soil analysis. It's a great value for the money and has 20 tests total (5 each for Soil pH, Nitrogen, Phosphorous and Potash). Instructions were straightforward and easy to understand.

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.
