As a fertilizer synergist, it is the raw material of polypeptide urea, polypeptide compound fertilizer and controlled release fertilizer, which can promote the absorption of nutrients by crops such as grain, vegetables, fruits and flowers, and at the same time, it can improve the efficacy when used in combination with pesticides. The research and application results at home and abroad show that polyaspartic acid is an effective plant nutrient absorption promoter, which is suitable for many plants and soils.
Extended data
Polyaspartic acid is widely used in industrial circulating water, oilfield water, boiler water, reverse osmosis water, seawater desalination and other water treatment fields. It is excellent in the system with high hardness, high alkalinity, high PH value and high concentration multiple, and its scale inhibition effect is better than that of ordinary phosphorus-containing scale inhibitors.
Using this product instead of phosphine-containing water treatment agent can avoid eutrophication and secondary pollution of water body. 1996, American Dong Na Company won this year's "American President's Green Chemistry Challenge Award". Subsequently, German, Japanese and China also started R&D projects in the late 1990s, and all of them were successful.
