Chementator: A ‘smart’ fertilizer

By Gerald Ondrey |

Last month, Uralchem OJSC (Moscow, Russia; www.uralchem.com) started production of a new fertilizer, called ASN 32:0:0:5, at Kirov-Chepetsk Chemical Works, OSJ. Granules of the new ASN formulation have a gradient structure with a high concentration of ammonium sulfate on the surface and a high concentration of ammonium nitrate on the inside. The combination of these two salts makes it possible to supply crop plants with nitrogen throughout the entire growing period. Sulfur is said to improve the material quality of grain, especially its baking characteristics, and increases oil content in oil-producing crops and protein in legumes. The ability to activate scarce and costly phosphorous reserves is also a feature of ASN 32:0:0:5; over 20% of the phosphorous fertilizers that are now applied cannot be adsorbed by plants, says the firm. This feature of the new product makes it possible to use previously applied phosphorous as an alternative source of phosphorous nutrition, the producer adds. The fertilizer is optimal for growing rapeseed, grain, potatoes and other traditional crops grown in Europe.   Click here for full pdf version of this article – includes all graphs, charts, tables, and author information
