Luster Leaf Products 1663 80 Professional Soil Test Kit, Green

I cannot use this kit. I have tried and failed. The filter comes off, the solutions sit, without changing colour. Not sure what i am doing wrong.

Box arrived damaged but, contents were fine so, wasn't overly bothered.

The instructions state ""You may feel strong resistance while filtering" I did... then heard a crack and the cylinder body has an inch long crack. I managed to complete the N test and the P test, but on the K test, the soil solution was leaking directly into the filtered collection tube. Not sure if a manufacturing defect or just being over butch, when not knowing exactly what to expect. Please advise how I get a replacement filtering device, the website won't open for me, and I'm outside the Amazon return period. The tests themselves are reasonably straight forward and the N and P tests returned valid results.

PH test worked somewhat. All other tests resulted in N0, K0 and P0. Followed instructions perfectly. Even tried testing soils extracted from potting mix - still all zeros. Beware, probably many faulty batches. Very Poor experience, and many hours wasted.

It can't be used for 40 tests only 10 max

Good enough for average backyard gardener. Yes, it's not as accurate as sending in a soil sample. Takes a little getting use to use, but gives you a general idea of what and how much to amend to your garden soil. I have black, hummus rich, loamy garden soil (it's very pretty), but am depleted of nitrogen and potassium. I had amended in spring knowing my soil was likely deficient, but I didn't realize I wasn't amending enough nutrients. My high intensity garden is 350 sq ft in size. The instruction and info sheet included was insightful with how much I should be amending based on test results. Very happy with end results. Will order again when I run out of test solutions in the future.

The item was just as described, Easy to use, repeatable results. Told me what is needed for a good healthy garden. Thanks

Super das es dieses Set mit den verschiedenen Tests gibt. Ich benutze es im Kleingarten um rauszufinden was meinen Pflanzen fehlt, natürlich kann man auch an den Blättern der Pflanzen erkennen wenn Mangelerscheinungen auftreten aber damit das garnicht erst passiert ist es gut wenn man vorher weiß was dem Boden fehlt. Das funktioniert mit dem Set sehr gut, man muss sich nur ein wenig damit befassen, und wenn man es einmal ausprobiert hat dann geht es beim nächsten mal auch leicht von der Hand. Anleitung leider nur in Englisch aber anhand der Bilder und mit g... Übersetzer auch kein Problem. Würde es erneut kaufen. Klare Kaufempfehlung.
