phosphorus is an element that does not have the status of a Chemical fertilizer phosphorus gas produced from rock phosphate which has come from the mining results in current forecasts suggest that phosphorus reserves that can be used in agriculture will expire in the next 50 - 100 years.You can use it, and there is no expiration. The results will be in accordance with the substitute for phosphorus, and after the backup, and then go to all of the world's population is 2 in 3 food shortage due to agricultural products decreased (Cordell et al., 2009), therefore, slowing the loss of phosphorus and therefore are the main issue in the study of this study
framework.The main cause of loss of phosphorus from the soil, fill up the phosphorus needs of the plant Water Soluble phosphorus (Excessive soluble phosphorus), this will flow out with water and cause the phenomenon call ฟิเคชั่น (Eutrophication).For example, a pool of emerald pool has been built in King Mongkut's University of Technology Thonburi Emerald pool is wastewater from the building and the rain water flow through a gardening in the area around the rain and wastewater contaminated with phosphorusMake the Water Soluble phosphorus is used in the growth of the plant, especially algae, water phosphorus in soil and sediment phosphorus accumulation in the dead algae cells to be submerged and accumulated sludge.
