Geological history: the cycle of phosphorus in nature

The Cycle of matter – one of the most important patterns in nature. The water evaporates under the influence of the sun, rises into the atmosphere, and then in the form of precipitation returns again to the rivers and lakes. Plants grow from the soil, obsolete and turn into humus in the same soil. The same happens with many mineral substances.

Phosphorus and its properties

The Cycle of phosphorus in nature in its own way very interesting. In the natural environment this element is distributed in large enough quantities. Share its content in the earth is about 0,12%. The degree of spreading of chemicals in the bark he is on the thirteenth place. Large deposits of this substance does not exist. Phosphorus in nature Refers to the so-called multiple items.

Another property of phosphorus – its high degree of oxidation. Because in its pure form in nature, it does not happen. But it is part of the 120 minerals and their compounds, the most valuable of which are Apatite and phosphorites. Moreover, scientists have already identified the entry of this nutrient in plant tissue, fruits and seeds. Such substances are called phospholipids. The cycle of phosphorus in nature occurs when the birth and death of plants.

A Significant proportion of the phosphorus atoms found in the tissues of living organisms, protein compounds, DNA molecules and ATP. Biologists call it “music”. Another name – “the element of mind” because phosphorus activates the brain, it nourishes, boosts mental activity.

The Cycle of phosphorus in nature affects all layers of the ecosystem, except the atmosphere. It happens this way: in the course of their life microorganisms, soil acids gradually destroy apetitnye field. The elements of the phosphorus becomes part of a biochemical cycle. Available in soil phosphates nourish the plants. Phosphorus compounds are deposited in fruits and seeds.

Among the plants that are actively used in food animals and humans in the first place are legumes. They serve as food for humans and herbivores, and phosphorus is a building material for animal bones and human skeletons. This is the role of the calcium salt of phosphoric acid. If in the organism there is a deficiency, the body begins to suffer from different kinds of pathologies on this basis: bone fragility, etc. a Large amount of phosphorus contained in the teeth. Phosphorus-containing substances are subjected to chemical treatment during the digestive process, are broken down and synthesized into new organic compounds. Faeces phosphates re-enter the soil.

In the cycle of phosphorus in nature, actively interferes with the man, his reasonable activity. This element is widely used in match production. Many varieties of stainless steel coated with a thin layer of phosphate to make it more resistant to weathering. Similar treatment is subjected to products from alloys of zinc, aluminum, other metals. Of phosphorus compounds do drugs.

In the geological circulation of substances include fertilizers added to the soil in accordance with the needs of agriculture. For their production are also natural phosphates.

In some areas of the earth's species discovered in huge quantities concentrations of organic phosphates. For example, guano-bird droppings, in which a large proportion of phosphorus. It is found in the places of mass nesting grounds of birds – in the Pacific Islands, Peru, etc., individual Deposits of phosphate compounds in terrestrial rocks can tell you about different kinds of geological disasters, which massively killed animals. About global extinction of marine organisms says Bilina hypothesis phosphorite formation.
