The effects of Superphosphate on plants and the environment
Superphoshate is a fertilizer produced by the action of reacting concentrated sulfuric acid on ground phosphate rock. Calcium sulfate is a considerable waste produce of this process.
Ca3 (PO4)2 + 2H2SO4 → Ca (H2PO4)2 + 2CaSO4Superphosphate used world wide by as a fertilizer the farming industry and gardeners. It increases plant production by as much as 106% as long as the plants are getting the required amount of water for normal plant growth. Super phosphate does little if nothing if there is no rain or agitation so farms living in low rain fall areas tend to use other non water depended fertilizer. It was really bought to the market in the second haft of the 20th century when an economical way of spreading it came about. The Development of aerial topdressing in New Zealand started the market off it was liked as the fertilizer could be spread economically over large areas. Now in Australia Superphoshate is put in with the seed when sowing or spread with Superphoshate trucks as we are not as hilly as New Zealand.
It works by gradually decomposing in the soil, providing soluble phosphorus which is absorbed by roots and Tran located within the plant. Its benefits are it also contains Sulphur in the readily available form of sulphate for plants to take up. This makes it ideal for low fertility and cropping situations. The Calcium in Superphosphate can be important in some horticultural and hill country situations where it is uneconomic to use lime.
Phosphate is found naturally in bird poo or by the action of guano as a result there are large deposits found around sea bird colonies which can be and are mined. Nauru an island in the South Pacific is famous for it mining sties much of the soil was mined and much of the environment was destroyed.
One of the side affect of using superphosphate is that earth worms can not live in the superphosphate soil. As a result super soils will not have the structure and nutrients which worm provide. Large scale superphosphate use
