Phosphorus (P) management in agriculture is crucial for both environmental health and future availability of P resource. Application of P as fertilisers (organic or inorganic) often results in either P accumulation in soil or loss to water bodies, rendering them unavailable to crops. In this study, the mobility of inorganic (KH2PO4 (PP)) and organic (poultry manure (PM)) P sources, as affected ...

The three ways to test for phosphorus in water are: • The orthophosphate test • The acid hydrolyzable phosphate test • The total phosphorus test. Elemental phosphorus never occurs by itself in water, but always as some type of compound. These tests use different techniques . to measure the three main types of phosphorus in water:

Phosphorus is an element essential to sustaining life largely through phosphates, compounds containing the phosphate ion, PO 43−. Phosphates are a component of DNA, RNA, ATP, and phospholipids, complex compounds fundamental to cells. Elemental phosphorus was first isolated from human urine, and ash was an important early phosphate source.

Due to the burning of coal, the available oxygen gets depleted and it leads to incomplete burning of coal. Incomplete combustion of coal gives carbon monoxide gas. It is a very poisonous gas. It is dangerous to burn coal in a closed room. The carbon monoxide gas produced can kill persons sleeping in that closed room. Question 65.

Coal can also increase the level of macronutrients, particularly nitrogen and phosphorus. Most nitrogen in coal is released only upon heating, but Ahrens and Morrisey point out that the issue has not been well studied. A 1996 study of Spanish coals found that "little phosphorus was mobilised by water."
