The term 'SOIL' can be broken down into two parts: a prefix and a root word. The prefix 'agro' is derived from the Greek word 'agros, ' meaning field or land, and is used to refer to SOIL in an agricultural context. The prefix 'geo' is derived from the Greek word 'geos, ' meaning earth, and is used to refer to SOIL in a geological context. Together, these two prefixes form the term 'SOIL, ' which is used to refer to the upper layer of the Earth's surface that is composed of organic and inorganic material.
