Title: Easy to use soil testing
Review: Great product for making sure you know what nutrients your soils needs. The instructions were clear and simple. There are times when the test results may not match an exact color on the test window but you are really looking for a range result anyway. Overall, it was a great product for ensuring our trees and garden are properly cared for.

Title: Appears to work
Review: Works perfectly. Wanted to verify the acidity of my soil, but chose to buy this pack which would provide me with even more data! Haven’t used the others yetEnough materials for 5 tests of each component! Great bargain and a very helpful product

Title: Average
Review: Seems to work ok, but the 20 teats is misleading it’s 5 testa of each type which no one is just going to test the one thing so it’s more like 5 tests.

Title: Worth it
Review: Easy to use and relatively fast. Was able to get through several samples and start correcting soil right after test. But why can’t I buy extra capsules? I don’t need more containers…

Title: Garbage!
Review: Every single pH test reads 7.5, including soil that tested at 4.5 in a lab not two weeks ago. I can see both samples have different colors just from the pH chemical after adding, yet the digital reader just shows 7.5 every time.Plus they don’t include a color chart for you to at least try to eyeball it yourself.Complete trash and a waste of money.

Title: Perfect for science experiments.
Review: I chose this brand because it was cheaper than others and came more quickly than others. The tests were easy to perform And to read results. We used it for science experiments so it worked well. I’m not sure of the true accuracy, but for what we are doing it was pretty spot on.

Title: Pretty Darned Acvurate
Review: So far, I’ve only used the pH test, but I’m very happy with the results. I never worried about pH levels until this past year, when my garden really didn’t produce. Doing some research online, I found that pH levels play a critical role in a plant’s ability to absorb nutrients. Shortly after that, just by chance, I ran across an old Ferry-Morse pH and Fertility meter at a garage sale. For a buck, what the heck. I tried it, but it stayed pretty much between 7.0 – 7.5. Was my soil that bad, or was this thing not working? I mixed some vinegar into the soil, and it did show movement to the acidic range, but I still wondered, was it working?Moving ahead 3 months, I ran across a TestWest pH meter on Amazon. It looked pretty cool, it seemed a lot easier to use (just poke it into the soil), and it could be used on indoor plants, which isn’t specifically addressed with the Ferry-Morse. Once again, for under $15, what the heck. And also, to test everything further, I purchased this Luster Leaf Rapitest Digital Soil Test Kit . Like one of the other reviewers, I had used Luster Leaf’s other soil test kit, but found it difficult to analyze the murky colors against the color charts, so I decided to go with this digital kit. Besides, it sounded pretty easy. Mix it up. Put the test tube into the meter, press a button to let the meter read the color and give you the results. What fun.For the test, I used the soil from one of my indoor plants, a 4-1/2 foot hibiscus. I followed Ferry-Morse’s instructions, dug some soil out from about 3″ down, watered it, let it set and then tested it. The Ferry-Morse read 5.8. The TestWest read 5.9. Pretty darn close. To validate the results, I used the same soil sample with the Luster Leaf Rapitest’s pH test. Note: for the Luster Leaf’s soil test, I followed Rapitest’s instructions and set a bit of soil aside before watering it (they want to start with dry soil). After mixing the soil with the reagent and water, letting it set, placing it into the test chamber and pushing the TEST button, it lit up the 5.5 indicator–which means that the soil pH is between 5.5 and 5.9.I couldn’t ask for a better validation (other than spending another $50+ and sending a soil sample to a full-fledged lab). All three tests instruments read within the same pH range.I already amended my garden soil this Fall (before I purchased this soil test kit) with a high sulfur fertilizer and an organic soil acidifier. I’ll be testing my garden soil in the Spring with all four tests in this kit. I trust the results implicitly.

Review: Very good soil test. Please note: you must run the test in a dark place, otherwise the reader will show false results. This happens due to fact that the reader works with color recognition, which can be affected by strong light passing through the green cover.

Review: I was very keen on using this test to test my soil here in Australia.Unfortunately only the K one triggered a result. Tried it twice (once with really cloudy and once with less cloudy water.)I find it hard to believe that my luscious well maintained and well fertilised lawn is completely devoid of N+P.
