Bests & Worsts Reviews from Amazon

This test showed that our soil was slightly acidic, but completely deficient in all three nutrients more than once. After amending appropriately and still having issues, I decided to send in soil samples to a soils lab. Their findings were much different than this test showed. Nitrogen was ok. The potassium levels were at an excessive level (nearing toxicity to plants) and the phosphorus levels were very high. The pH was also alkaline, not acidic. After getting the lab results I tried running this test kit again only to find I was getting the same wrong results that it had always given me. I recommend having a professional lab do your testing if you have any problems in your garden at least once a year. It will let you know exactly what's going on and give you correct information and recommendations on how to mitigate the problems.
