Rapitest Soil Test Kit for Gardens, Vegetables, Flowers and Lawns. USA designed and assembled soil tester completely, quickly and accurately measures/analyzes soil pH acidity and garden nutrients

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…

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.

Was having issues with my tomato plants. The leaves were curling up. Bought this test to see if the nutrients were off. It was fairly simple to use. The instructions were a little confusing at first, but once you read them all, it’s pretty easy. “20 tests” was a little misleading. I thought it meant “20 of each 4 types” but this was not the case. What it’s actually saying is “5 tests of each of the 4 types” but other than that, it worked as expected.

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.

Awesome helped me determine which nutrients I lacked for my potato growth.

I am disappointed with this lawn soil test kit. I have very little faith in the accuracy of the test results. The shades of the colors produced during my testing do not match up with the shades of the colors on the reference slides. I have hit my lawn hard with fertilizer and yet I get no reading for Nitrogen or Phosphorus. Also, the fact that you only receive enough materials to do five complete tests seems like a rip off. I do not recommend this test kit and will not buy another.

Works great. Easy to use.

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.
