Plants integrate their environment. Their leaves absorb carbon dioxide from the air and utilize light energy to produce carbohydrates, proteins, and lipids. Water and inorganic nutrients, generally derived from the soil through roots, provide much of the physical support and the building blocks for plant function and growth. Plants respond to a great many physical and chemical conditions in their aerial and edaphic (soil) environments, such as temperature, light, relative humidity, carbon dioxide, soil moisture, soil strength, and soil chemistry. 

   Plant analysis determines the elemental content of a particular plant part for one or more of the thirteen essential plant nutrients. Using established sufficiency ranges, a comparison is made between the laboratory analysis result in order to assess the plant's nutritional status.
