Electronic version of Luster Leaf’s popular 1601 Soil Test Kit. The rapitest Digital Soil Tester utilizes advanced LED digital technology and patent-pending optical calibration system to read test colors. The system is calibrated to read small color variations that can be difficult to distinguish with the human eye. The tester is easy to use. Just follow the easy instructions for each soil pH, nitrogen, phosphorus or potash tests; slide the test tube in optical chamber and push the appropriate button to get the test results. Once you have your soil test results, the tester booklet tells you how to adjust soil pH and provides recommendations for fertilizers. The booklet’s pH preference list allows you to select plants for your soil’s pH or know how much to adjust the soil pH for your current plants.
Phosphorus runoff poses a threat to water quality. Some states restrict the application of phosphorus-containing fertilizer on non-agricultural lawn or turf. Check your local laws prior to purchase.

So I bought myself this test.
Took some dirt from the ground.
Swirled it all around
To find that
Nitrogen was what I lacking
Which, of course, sent me packing
To my home improvement store
I bought some blood meal
(It was on sale, what a deal!)
atop my soil
Nothing for days
Blood starts to boil
Then suddenly, my plants start to grow
Basil, tomato, zucchini, and carrot
So I highly recommend
You won't regret it
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
So I done another test, only adding a few drops of lemon juice to the pH test chamber, and a solution of uria (48-0-0) to the N test chamber instead of soil water, and after some good shaking, the pH was yellow and the N was purpule, I have attached a picture and you can see for yourself.
When this test kit tells you the pH is neutral it really is, and when it tells you have no nitrogen you really don't, and you better be spraying a whole lot of it till you get it to "adequate" level.
If you do no other tests, do this one! PH controls whether or not a plant can take up nutrients. All the fertilizer in the world will not help, if the PH is wrong. I purchased the full test set as well as this one so that I could do more frequent PH tests and in more places such as around shrubs, bushes, and trees, especially fruiting trees and bushes. I have been using these products for at least 20 years. This purchase was just to renew my supply. I can usually go 2 or3 years with a full Luster Leaf set plus an extra PH test set. Buy and use it!. It will save you money on fertilizer and you can have the best garden in the neighborhood!
Just my opinion...and we all know that gardeners have plenty of them! Happy growing!
