  • Effective and Easy-to-Use Soil Testing Kit - Highly Recommend!
Style: Soil Test Kit Size: 20 Tests
I recently purchased this soil testing kit from Amazon, and I’m thoroughly impressed with its performance and ease of use. The kit arrived promptly and was well-packaged. Upon unboxing, I found the instructions to be clear and straightforward, making the setup process a breeze. I used the kit to test the soil in my garden, and the results were both enlightening and helpful. The tests for pH, nitrogen, phosphorus, and potassium were simple to perform and provided quick, accurate results. This information has been invaluable in helping me understand my soil’s needs and in making informed decisions on how to improve its quality for better plant growth. 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. In summary, I highly recommend this soil testing kit to any gardener or homeowner looking to gain a better understanding of their soil’s condition. It’s a practical, user-friendly tool that delivers reliable results, and it’s definitely a worthwhile investment for anyone serious about gardening. ... show more

  • Messy but works!
Style: Soil Test Kit Size: 20 Tests
I have clay soil so for 3 tests (not PH) i let it sit about 20 hours but the soil was not really separating from the water so i skimmed the somewhat clean water from the top. Test results showed ok PH and Potash. But tests showed I have no nitrogen and minimal phosphates. I have not been able to grow my tomatos last few years so I knew something was wrong. According to the internet i just need some aged manure to fix the problem. This was a useful product but very messy to use. ... show more

  • Soil test kit. Not sure if this will give accurate results, but so far so good 👍🏾!
Style: Soil Test Kit Size: 20 Tests
I just received this product today, so I can't speak on effectiveness or quality but I will speak on my first impressions of this specific product, what it contains and explain how it works. I bought it fearing that my homemade chunky soil mix was lacking sufficient nutrients and because I can't afford an expensive comprehensive lab test, and because this one has fairly decent reviews, I decided to try it out. In this kit has 4 test component: 1. Acidity test (pH test) 2. Phosphorus test (P Test) 3. Nitrogen test (N Test) 4. Potash (K test) Each test is color coded and is accompanied by a pill that's color coded as well. The directions are very clear and detailed, but the pH test is the only test that gives it's results rapidly, you h to wait 24 hours (it's explains why in the instructions) My I don't have a proper pH tester so I can't speak on it's effectiveness but the results were indeed "rapid" 🤷🏾♀️ I will update after use thorough use ... show more

  • Nice, but there's some issues.
Style: Soil Test Kit Size: 20 Tests
I like that this kit did provide the needed information I needed about the soil for my sweet potato patch. The test procedure was simple enough and the results easy to determine. The reason I am not giving it 5 stars is because I haven't found out how to purchase refills for the essential capsules needed for each test. Furthermore, I find the product description a little misleading (perhaps unintentionally) because it states it's enough for 20 tests. They DON'T mean you can test for Nitrogen, or the PH, 20 times. No, what they provide is 5 capsules for each type of test. So you can only test for one element 5 times. That wouldn't bother me if Amazon listed refills next to the same product. I couldn't find refills at all on Amazon, or on the manufacturers website. Does that mean you have to buy the entire kit after only 5 tests forany one element? That would be a huge wasteof plastic for the environment. If you have more than one garden bed, 5 tests wouldn't last long, especially if you want to retest after soil corrections. I will update this review if I can find refills. I have emailed the company directly. Another reason I substacted a star is because the tiny gel capsules are hard to open and pour/aim the contents into a tiny 1/2" opening. The test would be invalid if you missed and some of the contents spilled outside the reservoir. A shame when you only would ha4 more capsules to use! ... show more

  • Not worth the money
Style: Soil Test Kit Size: 20 Tests
It’s a PITA. Going out to the multiple garden beds, trying to scoop the right amount of soil, making sure to not touch the insides of the capsule, all while trying to not tip the test over. It is worth it to just pay for a real lab to test the soil. That way you’re not having to do it multiple times. Also, you only get 5 capsules for each test, it’s not 20 PER test. ... show more

  • This should help the garden
Style: Soil Test Kit Size: 20 Tests
This is an economical way to test your soil. Perfect for my small vegetable gardens. I like that it has 5 tests for each feature: PH, N, P, and K. The PH test vial is a bit different than the other three, so you have to follow directions carefully to get accurate results. The kit includes recommended PH and nutrient levels for different plants. That was very helpful. ... show more

  • My garden was not producing....
Style: Soil Test Kit Size: 20 Tests
After three years of less than abundant produce, I decided to test the soil. I am so glad that I did. I tested using samples from four different areas. The results were consistent in that my soil was deficient in two areas. Armed with this information, I went shopping and purchased the products that would re-balance my soil. We are all anticipating better results!. Next spring, I will test again to be sure that I am staying ahead of the depletion of minerals. The only down side, is the kit vials are small and hard to read. That would not deter me from using again. ... show more
