4.0 out of 5 stars Great product overall March 1, 2008

By Raymond J. Van Eperen

I just purchased this kit recently and tested my soil. I had tried an electronic one (a different brand) and I was not able to get a good reading - waste of $20. This kit worked great. It was simple to use and seems to be very accurate. I would have given it 5 stars except for the one comment the previous reviewer mentioned. You have to be very careful about empying the capsules into the tester. It's not the easiest thing to do, but not really that big a deal. I didn't really have a problem reading the results as long as you get it in the right light. For the price, a very goed product that I highly recommend.

4.0 out of 5 stars Works well for the price July 5, 2008

The instructions are somewhat involved for this tester. However, it is far cheaper than sending 10 samples to a lab for processing. You do need to allow up to 24 hours for your samples to settle after mixing with water; "Rapid" is in comparison to sending the samples to a lab. The actual tests of the water samples is completed in 10 minutes. My only, rather minor, complaint is that the blue dye (Phosphorus test) tended to adhere to the plastic test capsule, requiring a bit of cleaning with toweling between each test.

1.0 out of 5 stars Not accurate at all August 31, 2009

By R. Brinkerhoff

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.
