Review: Pretty Darned Acvurate - 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 desertcart. 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. Review: Takes the guess work out of building your soil! - Living in an area of red clay soil, building a garden spot can be challenging. I have added organics, compost, as well as fertilizer. But I was still at a loss as to whether I had accomplished my goals or not. the Luster Leaf 1605 Rapidtest was exactly what I was looking for. You don't have to mix a chemical with water and then look at a color chart and try to find the color closest to your tube. There is no guessing with this kit. It reads the color for you. It has easy to follow instructions and gives you fast results which take out the guess work. I even retested the same soil to see if I would get consistent results or if the meter would give me a different reading. It was dead on, and it made me feel I was getting a good test. After testing the soil it has instructions as to what you need to do to correct your soil with what to add and even how much. Very satisfied. ## Features - Power Source Type: Battery Powered ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00FGPLZZS | | Best Sellers Rank | #23,638 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #16 in Soil Test Kits | | Brand Name | Luster Leaf | | Customer Reviews | 3.9 3.9 out of 5 stars (1,369) | | Global Trade Identification Number | 00035307016058 | | Included Components | Digital Soil Kit | | Item Type Name | Digital Soil Test Kit for pH, N, P and K | | Manufacturer | Luster Leaf | | Style Name | Digital Soil Test Kit | | UPC | 035307016058 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Luster Leaf - **Global Trade Identification Number:** 00035307016058 - **Style:** Digital Soil Test Kit - **UPC:** 035307016058 ## Images ![Luster Leaf 1605 Rapitest Digital Soil testing Kit - Image 1](https://m.media-amazon.com/images/I/712i1Is9VzL.jpg) ## Questions & Answers **Q: Is this kit for a one-and-done test? If so, where and how much are refills for this product?** A: This test has several capsules for each test you want to run. My soil was really depleted. So I tested the first time to see what it needed, and then added those nutrients, and a week later tested again. I used the recommendations on the instructions to "fix" the soil, and it worked really well. The kit is easy to us. Read the FULL INSTRUCTIONS on the inside. The short version does not work. It will take a few hours or even days for some, because you have to put the soil in "purified" water, and let the soil settle to the bottom and the liquid become as clear as possible. I bought these on Amazon and if I remember right paid less than $10 for the complete kit. It was cheaper that way. I love these tests. Hope this was helpful. **Q: can you use it for several seasons.. or do the chemicals go bad once opened to the air?** A: The chemicals are in capsules. I used mine throughout the season last year on multiple foot plots around our property. Each variety of capsule is in its own sealable baggie also. You should be good as long as you keep them away from open moisture. **Q: how many capsules do you get and how easy are they to find?** A: There were 10 capsules for each test, easy to do, and fairly accurate I think. I'm a science teacher and have used this type of test before. They were color coded and in separate bags. **Q: Can i get spare capsules for the tester on amazon?** A: If you want to test across multiple seasons, look for "Luster Leaf 1880 Rapitest Tester Electronic 4-Way Analyzer, Soil". The meter can be used over and over without regard to having any chemical capsules to use. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pretty Darned Acvurate *by O***J on November 5, 2018* So far, I've only used the pH test, but I'm very happy with the results.

Very satisfied. ### ⭐⭐⭐ Complicated and incomplete *by D***S on September 5, 2024* I do container gardening in Arizona and wanted to see what my soil quality was. This kit is hard to figure out and the instructions are in very small print. The markings on the test tube are almost invisible and become totally so when powdery soil is added. The reagents are in plastic capsules, which are very difficult to open without spilling reagent. A pipette is required but not supplied. I found an empty Scalpicin container and was able to use it as a dropper. All these things compromise accuracy. I would not recommend this kit. ## Frequently Bought Together - Rapitest Soil Test Kit for Gardens, Vegetables, Flowers and Lawns.
