How To Build Rock Phosphate Plant Eritrea
The phosphorus cycle — Science Learning Hub
Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO43), loed in water, soil and sediments. The quantities of phosphorus in soil are generally small, and this often limits plant growth. That is why people often apply phosphate fertilisers on farmland. Animals absorb phosphates by eating plants or planteating animals.
Phosphorus Cycle
The phosphorus cycle is how phosphorus obviously cycles its way through the environment, both through the biotic mechanisms like when plants take it from the soil and a biotic mechanisms like when rocks are withered and eroded and give off their inorganic phosphates into the water. So phosphorous typically is used in biological systems as phosphates an important ingredient and things .
Sulfuric Acid in the Phosphate Fertilizer Industry
Sulfuric acid is used as a key first step in the production of both MAP and DAP, after which it is mixed with phosphate rock to produce phosphoric acid. And since the phosphoric acid production process consumes energy, an onsite sulfuric acid plant – a net producer of energy – is a critical part of the fertilizer production process.
