I tried Rapitest to test soil in a part of a garden where a couple of perennials are not growing (but not dying either). This was the first time I tried a soil test. I followed the instructions to the letter but after two tries the same color result (very dirty olive green) doesn’t match any of the colors listed, so I am not sure what to make of it.
Have you tried contacting the manufacturer?
I hear this is probably the least reliable method of soil testing. Personally I have one of those drop down meters that measures light, pH, and moisture. I have read mixed results on the accuracy of the pH on these, but they do a fairly good job of measuring light and moisture if they're not broken.
The most reliable test I've had was the one offered through my county extension service. That is probably the hardest one to do, but it is the most accurate. They send it off to a lab for analysis and it is very detailed.
