Environmental Concepts 1663 Professional Soil Test Kit with 80 Tests

This kit was used to test 6 samples of soil. It was easy to use and I believe the results are very accurate.

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.

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.

Product was faulty: pH bottle had leaked. When screwing the plunger down on the filtering device, the O-ring was displaced from its nested position in the plunger. I replaced the O-ring 3 times, but the same thing happened. I watched several videos on using the soil tester, but was unable to match the resulting nutrient test colours with those in the reading colour charts -- N test repeatedly was green (once milky white), should have been a shade of pink. P test changed from Depleted to Surplus within 20 seconds while waiting for solution to settle. Could never make any sense of the K test results. I emailed Luster Leaf for clarification of instructions and advice but they didn't reply

Best thing to do first, read the directions on how to use you soil tester, they the rest is easy to adjust your soil.
