I found here how to do a pH test:

You put a sample of your soil in the tube, add a few drops of test solution, shake it up and leave it for an hour or so to settle.
The solution in the tube changes color according to the pH of your soil. Compare the color of the sample with the color chart that came with the kit. Matching colors will tell you the pH of your sample.

Can anyone tell how to do nitrogen soil test, fosfat soil test and soil test calcium. Completely from the start just as it written for pH. Please I really need it. From the start detailed as in pH example.
