I presume you are asking why Pedological language is so technical. Pedology is the science of the soil such as Botany or Zoology. As such, it has a language of its own. All sciences have special terminology used for communication between the scientists.
I presume you are not a soil scientist or Pedologist. In that case you will need to get the assistance of a soil scientist friend to help you. Scientific terms always have a precise definition to avoid confusion between scientists and so that observations or results can be duplicated. Progress of the science depends on this precision.
We are glad to hear that you are interested in soil science and good luck.
