This test is a quick, inexpensive way to monitor the approximate acidity or alkalinity of your soil.
Much greater accuracy can be achieved with a pH meter.
This is a great little test. The instructions are very clear and easy to follow and the test itself is simple to perform. A great tool for monitoring the pH of pH sensitive plants like container grown blueberries without having to get lab soil tests for every container.Review by Steph (on 6/11/12)
