    • Easy to use soil testing
Style: Soil Test Kit Size: 20 Tests
Great product for making sure you know what nutrients your soils needs. The instructions were clear and simple. There are times when the test results may not match an exact color on the test window but you are really looking for a range result anyway. Overall, it was a great product for ensuring our trees and garden are properly cared for. ... show more

Works perfectly. Wanted to verify the acidity of my soil, but chose to buy this pack which would provide me with even more data! Haven’t used the others yet Enough materials for 5 tests of each component! Great bargain and a very helpful product

We were originally only sent the instructions and none of the testing kits, but once we got our replacement they worked great! Very user friendly and easy to read results!

Style: Soil Test Kit Size: 20 Tests
Seems to work ok, but the 20 teats is misleading it's 5 testa of each type which no one is just going to test the one thing so it's more like 5 tests.

    • Worth it
Style: Soil Test Kit Size: 20 Tests
Easy to use and relatively fast. Was able to get through several samples and start correcting soil right after test. But why can’t I buy extra capsules? I don’t need more containers…

    • Garbage!
Style: Digital Soil Test Kit Size: 25 Tests
Every single pH test reads 7.5, including soil that tested at 4.5 in a lab not two weeks ago. I can see both samples have different colors just from the pH chemical after adding, yet the digital reader just shows 7.5 every time. Plus they don't include a color chart for you to at least try to eyeball it yourself. Complete trash and a waste of money. ... show more

Style: Soil Test Kit Size: 20 Tests
I chose this brand because it was cheaper than others and came more quickly than others. The tests were easy to perform And to read results. We used it for science experiments so it worked well. I'm not sure of the true accuracy, but for what we are doing it was pretty spot on.
