Indium is the 68th most abundant element in Earth's crust at approximately 50 ppb. This is similar to the crustal abundance of silver, bismuth and mercury. It very rarely forms its own minerals, or occurs in elemental form.
In fertilizer, phosphorus comes in the form of phosphate, which dissolves over time to strengthen the root system and encourage longer plant growth. Some of the functions of phosphorus are to: 1  Stimulate growth. 2  Phosphorus gives plants a strong starting point in developing a root filter system in the soil.or example, if the fertilizer analysis is 12-2-14, the fertilizer contains 2% phosphorus. The other numbers indicate nitrogen and potassium, respectively. It should be noted that some municipalities ban the use of phosphorus on lawns.
Uses: Some phosphate rock is processed to recover elemental phosphorus. Pure phosphorus is used to make chemicals for use in industry. The most important use of phosphate rock, though, is in the production of phosphate fertilizers for agriculture.Some is used to make calcium phosphate nutritional supplements for animals.Substitutes and Alternative Sources: Phosphorus is so important to life, that there is no substitute for it in agriculture.hosphorus is a very important piece of the DNA and RNA molecules of which all life is formed. It is also important for the development of teeth and bones. The name phosphorus comes from the Greek word phosphoros, which means bringer of light. Phosphorus is mined in the form of phosphate rock.
