The results of laboratory investigations into the aerobic biodegradation of chelating compounds in water medium under static test conditions, are presented. It was found that ethylenediaminedisuccinic acid (EDDS) is more readily biodegradable than ethylenediaminetetraacetic acid (EDTA) commonly used in the manufacture of liquid fertilizers. Biodegradation was evaluated on the basis of the compound decay and the changes in COD.
