OXYGEN SUSTAINED RELEASE AGENT, MANUFACTURING METHOD THEREFOR AND OXYGEN SUPPLY METHOD

摘要

PROBLEM TO BE SOLVED: To provide an oxygen sustained release agent which can maintain oxygen sustained release performance for long time, can be manufactured safely, has no generation of phosphorous-derived eutrophication which is large in environmental load even when eluted into water such as river or port, can avoid increase of only phosphorus in a plant culture medium and can simplify a process of addition to soil.SOLUTION: There is manufactured an oxygen sustained release agent manufactured by a manufacturing method of oxygen sustained release agents having a process for mixing hydrogen peroxide water and a compound represented by the following chemical formula 2: aRCObR(OH)cHO (Chemical formula 2), where a:1 to 5, b:0 to 1, c:1 to 7 and R:alkali earth metal.SELECTED DRAWING: None
