    • Perfect for science experiments.
Style: Soil Test Kit Size: 20 Tests
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.

    • Nice & Easy Soil test
Style: Soil Test Kit Size: 20 Tests
This is my first time using a product like this. I have a small garden and it wasn't producing as much as it did in the past so I thought I would see if the soil needed additives, also called amendments. This test was somewhat easy after I got the hang of it, you have to really read the instructions as one test is slightly different than the other tests. The 20 tests turns out to be really just 5, you use all 4 testing units, which requires one of each of the capsules mixed with water and soil. I don't know why you would just test for 1 of the 4 components, common sense says you test for all 4 each time you test. All in all an easy test once you get the hang of it. I found that getting the small capsules open was a problem until I took a small sharp knife, (I used an X-Acto) to just cut the outer shell so it would open easier and I opened it over a piece of paper in case I spilled any. As with any test that uses color as the basis of degrees of component, you have to interpret the colors on the plastic tester. I would up holding mine up to a window that had good north light so it wasn't too bright and did my best to interpret the results. This was far cheaper than buying a professional test and sending it away, but I don't know if the results were better or worse. Time will tell as I amended my soils and planted some herbs. You need to know what you're going to plant in an area to make this work as different types of plants require different types of soils. I deducted 1 star for 2 reasons, first it seemed like there would be 20 different tests when instead it is a 4 part test you run so there are really only 5. And the instructions are not the easiest to follow in the beginning. Whether this is better than a professional test I don't know. ... show more

    • Soil health
Style: Soil Test Kit Size: 20 Tests
I’ve ordered multiple items from this company, never had any problems. They work as stated. Since I got the digital reader it just helps trying to match the color. Nothing hard about it. Very easy to use. Seems to have givin me the right results in my current grow. Nothing is deficient.

    • save your money on the digital reader, get the manual strips
Style: Digital Soil Test Kit Size: 25 Tests
The media could not be loaded. So the digital reader says this dirt is low ph, but the color strip for manual reading says that would be the highest possible ph. So that’s confusing and less than helpful. I just did a test with food color and the green is indeed high ph, and orange read as extremely low. Since the digital reader is literally just reading the color for you, I would recommend getting the manual reading strips and save your money. Do you trust your ability to tell the difference between green and yellow or red? Unless you’re colorblind you can probably do a better job than the little cheap machine. I’m guessing the reader in the device didn’t like how opaque my samples were and defaulted to low. For the difficulty of opening the capsules I just used scissors at one end over the directional pamphlet and any that spilled I tipped into the tube using the crease of the paper. ... show more

What I particularly appreciate about this kit is its comprehensive nature – it covers all the essential elements that affect soil health. Plus, the durability and quality of the components assure me that I can use this kit for seasons to come.

    • Results are inaccurate
Style: Soil Test Kit Size: 20 Tests
Results are inaccurate. I tested 4 different samples from completely different parts of my property. They all came out exactly the same, basically showing no results. Only the PH test had a reading and they all showed the same - 6.5. I can't imagine that all areas of my garden have no nutrients at all. In addition, the capsule with the testing compound is very difficult to open without spilling the material. Don't waste your money. Everything online says to have your soil tested through your State Extension Service, but they suggest to do it in the Fall or Winter. ... show more
