nutrient cycle





























a nutrient cycle (or ecological recycling) is the movement and exchange of organic and inorganic matter back into the production of matter. energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic. mineral cycles include the carbon cycle, sulfur cycle, nitrogen cycle, water cycle, phosphorus cycle, oxygen cycle, among others that continually recycle along with other mineral nutrients into productive ecological nutrition.

nutrient cycle
in 1926 vernadsky coined the term biogeochemistry as a sub-discipline of geochemistry. however, the term nutrient cycle pre-dates biogeochemistry in a pamphlet on silviculture in 1899: "these demands by no means pass over the fact that at places where sufficient quantities of humus are available and where, in case of continuous decomposition of litter, a stable, nutrient humus is present, considerable quantities of nutrients are also available from the biogenic "nutrient cycle" for the standing timber. in 1898 there is a reference to the nitrogen cycle in relation to nitrogen fixing microorganisms. other uses and variations on the terminology relating to the process of nutrient cycling appear throughout history:
