Plants must have phosphorus for normal growth and maturity. Phosphorus plays a role in photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement and several other processes in plants. A plant must have phosphorus to complete its normal production cycle.

Where is phosphorus mainly stored?

Nitrogen and carbon are also part of DNA. Unlike carbon and nitrogen, most of the phosphorous on Earth is stored in soil and rocks in the form of phosphate.

Which phosphorus is least reactive?

Phosphorus occurs in at least 10 allotropic forms, the most common (and reactive ) of which is so-called white (or yellow) phosphorus which looks like a waxy solid or plastic. It is very reactive and will spontaneously inflame in air so it is stored under water.

Will phosphorus kill you?

White phosphorus is extremely toxic to humans , while other forms of phosphorus are much less toxic . Chronic (long-term) exposure to white phosphorus in humans results in necrosis of the jaw, termed “phossy jaw.” EPA has classified white phosphorus as a Group D, not classifiable as to human carcinogenicity.

How phosphorus was discovered?

Hennig Brand discovered phosphorus in 1669, in Hamburg, Germany, preparing it from urine. (Urine naturally contains considerable quantities of dissolved phosphates.) Brand called the substance he had discovered ‘cold fire’ because it was luminous, glowing in the dark.

Are phosphorus bad for you?

The mineral is needed for healthy bones, but excess amounts may disrupt calcium absorption as well as hormonal regulation of phosphorus , calcium and vitamin D. Additional studies suggest that excess phosphorus may contribute to other chronic diseases as well, including type 2 diabetes, some cancers and even obesity.

Phosphorus in the body?

Phosphorus works with calcium to help build bones. Phosphorus also plays an important structural role in nucleic acids and cell membranes. And it’s involved in the body’s energy production. Your body absorbs less phosphorus when calcium levels are too high, and vice versa.

How phosphorus affects plant growth?

These excesses of phosphorus have several undesirable effects. It has been shown to interfere with a plant’s absorption of iron, manganese and zinc, resulting in yellowing of leaves and poor health of the plant . So before using bone meal or a high phosphorus fertilizer, do a soil test.

How phosphorus helps the body?

Function. The main function of phosphorus is in the formation of bones and teeth. It plays an important role in how the body uses carbohydrates and fats. It is also needed for the body to make protein for the growth, maintenance, and repair of cells and tissues.

How long will phosphorus last?

According to some researchers, Earth’s commercial and affordable phosphorus reserves are expected to be depleted in 50– 100 years and peak phosphorus to be reached in approximately 2030. Others suggest that supplies will last for several hundreds of years.

What contains phosphorus?

Phosphorus can be found naturally in foods (organic phosphorus) and is naturally found in protein -rich foods such as meats , poultry , fish , nuts, beans and dairy products. Phosphorus found in animal foods is absorbed more easily than phosphorus found in plant foods.

When is red phosphorus spontaneously combustible?

It may also be sanded off the matchbook strike plates, but may result in paper contamination. Hazards: Although it does not ignite spontaneously like white phosphorus , red phosphorus is a flammable solid and is readily combustible .

How phosphorus is extracted?

Organic phosphorus must therefore be extracted from soil before it can be quantified and identified. Extraction is used to determine the total amount of organic phosphorus in soil, to obtain it in a form suitable for subsequent speciation, or to estimate its mobility, solubility, or biological availability.
