How to Test Soil With Rapitest
- 1). Gather a soil sample of your gardening soil and place it into the test chamber up to the fill line.
- 2). Unscrew the "pH" bottle that contains pH testing capsules. Split a capsule in half and empty the powdery contents into the test chamber.
- 3). Use the water dropper to add distilled water to the test chamber up to the "water fill" line.
- 4). Place the cap on the test chamber and shake it vigorously.
- 5). Let the test chamber sit still for a minute to allow the color to develop.
- 6). Hold the test chamber against the color comparison chart and find the matching pH by color.

- 3). Use a water dropper to suck up some of the dirty water that has risen to the top of the container. Empty the dropper into a clean, empty test chamber up to the fill line.
- 4). Split either a nitrogen, phosphorus, or potash capsule and empty the contents into the test chamber. Place the cap on the test chamber and shake it vigorously.
- 5). Let the test chamber sit still for a minute to allow the color to develop for 10 minutes. Hold the test chamber against the color comparison chart and find the matching pH by color. Repeat the steps to test the soil for other elements.
