    • I compared results to actual lab results
Style: - Size: 40 Tests
This product is easy to use and pretty accurate. Just to give you some background on me and why I can support that claim- I am an Environmental scientist and hopefully soon to be Professional Soil Scientist (once I pass some exams). So this is why I say it’s pretty accurate. I tested my yard and flower beds. Because of my profession, I have access to a soil probe. I took multiple samples across the yard between 6-12” deep and submitted that as 1 composite sample and did the same for my flower beds. I submitted these samples to the Texas A&M Agrilife Extension (i’m In Houston, Tx) and I just got results back. (They are very affordable and will even consult with you about results) First, let me tell you what this test kit told me. It told me my Nitrogen (N) and Phosphorous (P) is depleted, I maxed out on the Potassium (K) and my pH was at maximum of at least 7.5. My actual soil results confirmed I have 0 ppm Nitrate-N, very little P at 5 ppm, K reported at 108 ppm but does not exceed the “high” or Critical Level and my pH is at 8.0. I would say that considering how cheap this kit is, it was pretty accurate certainly gave me enough information to steer me in the right direction. Now I just need to apply my hard earned knowledge in Soil Fertility to real life, instead of just theory. =) I hope this information helped someone feel More confident in using this kit. *Update- I passed one of my exams and am now a Certified Professional Soil Scientist. Had to brag on myself I’m so excited, yay me! ... show more

    • Easy to use. Worked great.
Style: - Size: 40 Tests
This product was great. I have a raised garden bed and I’ve never checked the soil until I bought this product and it told me that my soil definitely had no nutrients left, so glad I ordered it and was able to get all of the nutrients it was missing!

    • Not sensitive enough and too few capsules
Style: - Size: 40 Tests
I can't say for sure it's accurate but I sure hope so because I bought fertilizers based on these readings. I would not buy again because so few capsules are included and replacement ones seem hard to get at a fair price. I have a whole empty yard to plant, which has miserable clay soil I need to ammend, fertilize or replace depending on the needs of each plant. I tested five zones of existing soil, and tested a plot where I had mixed in ammendments galore the year before, to see if I'd achieved normalcy there, and had wasted a couple "pills" learning the technique... and tgat was all, I ran out of one "pill" type. I had hoped to be able to double check a second sample from each zone, and also test them all again after working on the soil. But what they give you just doesn't go far at all. And you can't use the rest once one type runs out. What good is checking your potassium level if you can't check your nitrogen, right? You need the whole set of results to plan what to add. I hated the testing vials. They're skinnier on the bottom than the top, making them a bit unstable. It seems safe enough, if you're worried about that. I was not especially careful and likely got all four powders on my hands, but despite being a very sensitive person, I got zero irritation (washed well, as soon as I was finished, of course). Also none of it smells at all. Though I certainly wouldn't do it with a fan on or anything else that'd stir up the dust into your eyes or breathing air. Ideally I'd love to see a manufacturer make two kits, one for soil that is known to be poor, one for normal, and the testing chemicals modified in type or concentration so as to provide an appropriate level of sensitivity. Because most of my tests didn't change color at all our soil is so lousy- I'm right off the chart, maybe by a little or maybe by a lot. I see a lot of other reviewers saying the same. I think most people who buy things like this do so because their soil is known to be poor. So it's annoying that the kit is calibrated to leave so many of us outside the range. If you have pretty good soil but just want to fine tune it, then you might find the kit great for your needs. In the spring I will fertilize according to what this kit told me, and I guess give it time to settle in, then maybe in the fall, source some more "pills" for this so I can see what levels I get then. I'll make just small changes, to hopefully get into a range where the kit can give a reading, and then I can add more fertilizer with precision. Or maybe I should just send some soil to a lab. Probably easier & will give me more confidence. ... show more

    • Saved my garden!
Style: - Size: 40 Tests
Review Image by Garden-Mom Garden-Mom
Tests are easy to perform. Only negative is that the containers spill easily. But seriously, this kit saved my garden! I had set up 5 large new raised beds after a recent move. I purchased a high quality organic garden mix from a reputable supplier, and planted my early spring (cold weather) seedlings. For two months, most things stopped growing. I tried giving some fish emulsion, and plants didn't budge. Leaves started turning yellow, then purplish...I was guessing there were significant deficiencies in the soil I received, even though the blend was supposed to have 20% compost. I decided to purchase this kit before throwing tons of additives in my soil, just to see what the issue was. After testing, no wonder my plants weren't growing--there was literally zero Nitrogen or Phosphorus in the soil I received! My plants were starving to death. I was able to confidently add significant amounts of the lacking nutrients, and my plants immediately perked up. I now know what needs to be mixed into the soil before I plant my summer crops, and have enough tests remaining to periodically check my soil! I was also able to reach out to the company that provided the poor mix I received. I showed them the shocking results of both my soil test and the sad pictures of my plants, and they agreed that it was not up to par with their normal garden soil product. They delivered 25 bags of compost, for free, to help get my garden back on track! ... show more
