    I just purchased this kit recently and tested my soil. I had tried an electronic one (a different brand) and I was not able to get a good reading – waste of $20. This kit worked great. It was simple to use and seems to be very accurate. I would have given it 5 stars except for the one comment the previous reviewer mentioned. You have to be very careful about empying the capsules into the tester. It’s not the easiest thing to do, but not really that big a deal. I didn’t really have a problem reading the results as long as you get it in the right light. For the price, a very goed product that I highly recommend.

    This review is from: Luster Leaf 1601 Rapitest Soil Test Kit (Lawn & Patio)
    I see other reviews on here talking about “send your soil in to a lab” or other alternatives to this product. Fact is, if you were willing to spend the money to send your soil to a lab, you probably wouldn’t be buying this. Probably like you, I bought this because it’s cheap and it’ll give you a basic idea of what’s going on in your garden. Here’s how it works:

    You get 4 vials, one for soil pH, and one each for Nitrogen (N), Phosphorus (P) and Potassium (K). Essentially, you place the directed amount of soil/water mixture into each vial, and add the contents of the corresponding color-coded capsule. The capsules look like pills, the type you can pull apart and the contents spill out. After you empty the capsule into the vial, you place the rubber cap on the vial, shake and let it sit for the specified amount of time. All the quantities and times are clearly listed in the manual. Each vial has a color chart that is near your soil sample window which allows you to compare the color to the chart. This is how you know where your soil stands as far as pH, N, P and K.

    I’ve seen some reviews on here saying it’s “impossible” to empty the capsules into the vials because they’re too small. True, they’re small but if you twist them and carefully pull them apart over the vial it’s really pretty easy. If you’re elderly or have trouble holding your hands still (or you’re just spastic), it might be a task for you but it’s still doable. It’s really not very difficult.

    I’ve tested my soil maybe 10 times using this product, and it’s never let me down. It doesn’t give you an exact number or anything, but any time I’ve shown low on something, I amended the soil and a few days later it tested fine and the plants looked healthier.

    It’s not extremely precise, but it’s reliable and it will definitely tell you if there is something dangerously askew in your garden. My suggestion to the guy that only uses the lab is that either he got a defective one, or he’s not cleaning them properly after each use.

    You should clean them with water thoroughly after each use and don’t mix them up. You don’t want to use the pH vial for the K test, or any other variant. Keep them clean, follow the directions and don’t mix and match.

    My only complaint is that the vials can be knocked over easily as they have an oddly poor center of gravity. Once the cap is on, who cares. But, when you’re filling them or trying to empty the capsule into them, it’s pretty easy to knock them over and that’s just a big bag of bollox.

    Anyhow, to sum up, for the money, this product can really, really help. If you’re looking for something more precise then spend some more money or send to a lab like the other guy said. If you just want to make sure everything is generally good in your garden, this will probably suit you just fine.

    Hope this helps

    The instructions are somewhat involved for this tester. However, it is far cheaper than sending 10 samples to a lab for processing. You do need to allow up to 24 hours for your samples to settle after mixing with water; “Rapid” is in comparison to sending the samples to a lab. The actual tests of the water samples is completed in 10 minutes. My only, rather minor, complaint is that the blue dye (Phosphorus test) tended to adhere to the plastic test capsule, requiring a bit of cleaning with toweling between each test.
