We always talk about organic, such as organic farming, organic vegetables, etc.

Then what is organic ? ?

If you ask customers in the market. You may simply get the answers “have small holes on the leaves” or “contain no chemical” .

Actually all living things are based on carbon. Soil contains three basic forms of organic carbon, the living, the dead, and the very dead. The living component contains all of the living organisms, including plant roots. The dead refers to any organic matter that is in the process of decomposition. The very dead material has completely decomposed, which include humus and charcoal.
