Essential plant nutrients; can cause serious water pollution in excessive quantities
compounds used in detergent formulations, which cause eutrophication when not removed in sewage treatment
Certain chemical compounds containing phosphorus Phosphogypsum Piles (Stacks): Principal byproduct generated in production of phosphoric acid from phosphate rock These piles may generate radioactive radon gas
Derived from the mineral apatite; any salt or ester formed by the reaction of a metal, alcohol, or other radical with phosphoric acid
An additive to drinking water to inhibit corrosion Phosphates create a protective coating on metal surfaces and reduces its chemical activity, which decreases the processes that lead to corrosion Zinc orthophosphate is commonly used to control corrosion, such as general corrosion, pitting, and lead or copper control
In fertilizer trade terminology, phosphate is used to express the sum of the water-soluble and the citrate-soluble phosphoric acid (P2O5); also referred to as the available phosphoric acid (P2O5)
A nutrient that causes excessive plant/algae growth if it reaches excessive levels in the reef tank Photoperiod - The period of time that the lights over the tank are turn on (length of day)
Phosphate --in the form of rock phosphate-- is a dry organic fertilizer used to boost phosphorous levels in the soil Rock phosphate is slow to dissolve in water, so adding it will benefit the soil over a period of years The phosphate found in many synthetic fertilizers is usually from rock phosphate treated with sulfuric acid to make it more soluble and thus more readily available to plants (called superphosphate)
Phosphate is a salt of phosphoric acid Phosphates are extremely important in living cells, particularly in the storage and use of energy and the transmission of genetic information within a cell and from one cell to another
A chemical compound that aids root growth and is essential in energy transfer It is commonly incorporated into beds as triple super phosphate (TSP) at time of planting
A mineral that helps calcium to strengthen the bones Phosphate is obtained from foods such as dairy products, nuts and meat The kidneys normally help to keep the right amount of phosphatein the blood In kidney failure, phosphate tends to build up in the blood High phosphate levels occur with low calcium levels in people with renal bone disease
A nutrient that can case uncontrolled growth of algae in the aquarium It can also toxic in high concentrations and must be kept to a minimum in reef aquariums Phosphate can be easily removed by a number of commercially available filter media
A salt of phosphorus found in such foods as meat, poultry, fish, dairy products, legumes, nuts, and soft drinks Reduction of phosphate intake may be necessary to help reduce kidney stone formation
A phosphate is a chemical compound that contains phosphorus. Phosphates are often used in fertilizers. Any of numerous chemical compounds related to phosphoric acid (H3PO4). Phosphate salts are inorganic compounds containing the phosphate ion (PO4^3-), the hydrogen phosphate ion (HPO4^2-), or the dihydrogen phosphate ion (H2PO4^-), along with any cation. Phosphate esters are organic compounds in which the hydrogens of phosphoric acid are replaced by organic groups (e.g., methyl, ethyl, phenyl), with one of their carbon atoms bonding to an oxygen atom in the phosphate group. Nucleic acids and ATP both contain phosphate; bones and teeth contain calcium phosphate. Phosphate rock (mainly calcium phosphate) is one of the four most important basic chemical commodities. Phosphates were formerly used in detergents, which washed into rivers and lakes, causing water blooms of algae and bacteria (see eutrophication); such use is now generally outlawed or regulated. Phosphates are still used in fertilizers, baking powder, and toothpaste
