Luster LeafProducts 1665 Professional Soil Kit with 200 Tests, Green

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.

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.

Unnecessarily complicated design and methodology for testing. User unfriendly and questionable accuracy. After completing 2 nitrogen tests I was unable to get a measurable result and the remaining test liquid would only provide another 10 tests if I was lucky. The chart to measure your potassium results is convoluted and filled with discrepancies. The phosphorus test was the only one which was measurable but I wouldn’t count on its reliability. Will never even attempt to use this product again. Will only keep as a reference for a product to avoid. I only rated one star because I had to. Would not even rate a quarter of a star. Complete waste of money. Look elsewhere if you want a test kit that works.

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.

I had never done it before but now that I have her realize it's easy and it helps me keep the ground for my garden in great shape
