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.
