Nutrition law of the minimum is considered an essential plant nutrient if the plant cannot complete its full life cycle without it. There are 16 essential plant soil nutrients, besides the three major elemental nutrients carbon and oxygen that are obtained by photosynthetic plants from carbon dioxide in air, and hydrogen, which is obtained from water. Plants uptake essential elements from the soil through their roots and from the air (consisting of mainly nitrogen and oxygen) through their leaves. Green plants obtain their carbohydrate supply from the carbon dioxide in the air by the process of photosynthesis. Carbon and oxygen are
Carbon sequestration sinks. Carbon sequestration is the process involved in carbon capture and the long-term storage of atmospheric carbon dioxide () and may refer specifically to: Carbon dioxide may be captured as a pure by-product in processes related to petroleum refining or from flue gases from power generation. sequestration includes the storage part of carbon capture and storage, which refers to large-scale, artificial capture and sequestration of industrially produced using subsurface saline aquifers, reservoirs, ocean water, aging oil fields, or other carbon sinks. Carbon sequestration describes long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global
