Beschreibung
Zusammenfassung:New chelated trace nutrients (I) for plants comprise the reaction products of at least one complex former (A) selected from sodium, potassium, sodium/ammonium or potassium/ammonium salts of N-(1,2-dicarboxyethyl)-D,L-aspartic acid and metal ions (B) derived from inorganic or organic zinc, manganese, iron (II) or copper (II) compounds. An Independent claim is included for the preparation of chelated plant trace nutrient fertilizers (I'), by reacting a complex former (A') having an imino group and multiple carboxylic acid groups with a compound (B') selected from the chlorides, nitrates, acetates and sulfates of iron, manganese, copper or zinc (or with a corresponding metal hydroxide, carbonate or oxide in presence of an (in)organic acid).
