  • Perfect for garden beds.
Style: - Size: 40 Tests
Arrived in great shape. The instructions are clear and it's easy to use. Matching the test results to the color scale charts was easy to see and understand. I had no problems with my test. I primarily used the kit to check the PH levels in a large bed, about 20x15 feet, and found slightly different results in different parts of the bed, which was good to know. Next time I want to check soil in an area I'm working in, I will buy this test kit. I recommend it as a good, quick, and easy-to-use kit. It doesn't replace or equal a State/University Agriculture department test for large projects, but it's great for getting a good reading of the soil condition for new plantings. ... show more

  • 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

  • Soil Test Kit
Style: Soil Test Kit Size: 20 Tests
Work as you would expect them to and thy are very simple to use. No negatives at all. Don’t know if they are accurate or not, but they work as described. Anxious to see if garden improves this season after using them. Definitely worth a shot.

  • 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

  • Much needed and easy to use!
Style: - Size: 40 Tests
Look - I should have done this 8 years ago. Nope. I fell for the marketing - the four applications a year of the recommended seasonal product. And every year my lawn would look horrible around August or September. In hindsight a wise soil chemist could have likely named the issue - deficiencies in crucial nutirents and a pH problem - just by looking at the weeds in the lawn. I am not a soil chemist. Other than the blonde in the front row of freshman chemistry which was only offered at 7.30am I found most of the class boring. Uninteresting. Incomprehensible. I would have flunked if it were not for her being assigned my lab section and giving me a reason to attend a 2.30pm Friday lab. While her name is long forgotten to the nearly three decades since that class, two things I did not forget: the way she looked at me with utter disgust one of the many times I failed to offer an even halfway compentent response to question, and the importance of following directions in chemistry experiments in order to obtain accurate results. Not being a soil chemist I did the test - on two different areas of my 3,000 square foot lawn. And what I found was that despite my poor attempts at regular lime applications the pH was 5.5. And my occasional and relatively inconsistent application of whatever fertilizer was both in season and on sale left me with a complete and utter deficiency in Nitrogen and Potassium (the N and the P of the N-P-K number). Which - as any soil chemist will tell you - results in the perfect growing conditions for goosegrass and violets - two realtively common weeds that are a regular sight in my lawn. In conclusion - think of this handy soil test as an insurance policy against applications of the wrong fertilizer - or in this case - insurance against wasting money applying fertilizer when the pH is 5.5. And oh yeah - perhaps I should do something about my longstanding policy of being utterly ignorant about chemistry. ... show more
