Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
No abiotic degradation study is provided. In general, fate and environmental data requirements do not need to be fulfilled because algae and algal products, used as soil amendment, are readily transformed in elements naturally present in the environment.In fact, it is acknowledge at the European level that the plant extracts appear to be biodegradable, with a low environmental impact (T.E. Tooby, JSC International Ltd).
In a work by Whyte (1981), soil NO3-N, K, Mn, Na, Cl and EC increased linearly with increasing applications. This alga had a low C/N ratio (11.9) and a high N concentration (2.3%), of which approximately 30 % was readily available as NO3-N soon after application. The kelp used as a soil amendment in this investigation resulted in increases in soil N, K and Mg which may be beneficial for crop production.
Furthermore, seaweed extracts including Ascophyllum nodosum extracts are included in Annex I of Directive 91/414/EEC, which requires a reduced package of studies for Plant Protection Products made from plants or plants extracts (SANCO Draft Working Document 10472/2003/rev. 5).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
