FREE Shipping
on orders of $99+*


Digitally test your soil with ease. Soil tests are performed in four separate color-coded tubes: green for testing pH, purple for Nitrogen, blue for Phosphorus, and orange for Potash. Capsules for each test are color-coded to match the corresponding tube’s cap. When testing, use the dropper to transfer the test solution into the test tubes, and the optical calibration system will recognize the hue specific to your soil’s pH and nutrient levels to provide results. Test Kit also contains a handy test tube-holder to secure all four tubes during testing while the color develops. Performs 25 tests: 10 for pH, 5 for Nitrogen, 5 for Phosphorus, and 5 for Potash. Includes test tubes, test capsules, dropper, and instruction booklet — complete with guidelines on how to fertilize and amend soil based on results.

Luster Leaf?? Rapitest?? Digital Soil Test Kit: Performs 25 tests? What happens after 25 tests? Do you throw it away?
Mavis B on Aug 11, 2017
BEST ANSWER: You can order refill test capsules directly from the manufacturer (Luster Leaf).
Will this tell me the numbers of each specific test?
Leigh B on Dec 5, 2019
BEST ANSWER: Sorry for the delayed response.
The device only gives numbers for the pH test.
For the other tests, the device only gives qualitative results, i.e., adequate, good, poor, insufficient.

Finally comfortable with soil tests
This takes the guess work out of soil test kits which never look like the color scale on the picture so I always doubt the accuracy.
