Is you soil fertile or poor? What are the main chemical characters of your soil? To get to know these, traditional method is to send soil sample to professional laboratories. There the sample is treated with solution. All the characters are obtained by testing the solution with different analytical instruments. This is OK but you have to wait for days or even weeks to get the results after you have paid a dear amount of money. Soil characters changed during the days and transforming (from solid to liquid). The change can not be tested.
