You must first send the sample in to a laboratory to have it analyzed for the various soil qualities. Once the lab has given you the test results you can begin to make your determinations. This is a VERY complex subject, one which agronomists study for years, and therefore much too complex to be answered here. However, you can take a look at the related link below to get an idea of where to start.
