Description of key information
With high probability, not harmful to soil microorganism when applied in low levels and with appropriate precautions
Key value for chemical safety assessment
Additional information
Data on the toxicity of the reaction mass of ammonium sulphate and potassium sulfate and sodium sulphate to soil microorganisms are not available. The assessment is based on data for ammonium sulphate since no data for the other components of the reaction mass i.e. sodium sulphate and potassium sulfate are available.
Studies of the effects of ammonium sulphate on three nitrogen-fixing soil bacteria and on total soil bacteria are available. The abundance of nitrogen-fixing cyanobacteria in a Spanish rice field was reduced significantly following a single ammonium sulphate application even at the lowest application of 82.5 kg/ha (Fernández Valiente et al., 2000, cited in OECD SIDS 2007). In another experiment, biological nitrogen-fixing ability in a field under crop rotation in was reduced (nitrogen-fixing legume bacteria) or eliminated (nitrogen-fixing blue green algae) by over thirty years annual application of 377 kg/ha ammonium sulphate (Martensson and Witter, 1990, cited in OECD SIDS 2007). The lowering of soil pH by ammonium sulphate was the main cause of the reduction in the nitrogen-fixing capacity of the soil. In this experimental field, total soil biomass was reduced by less than 50% relative to unfertilized control plots (Witter, Martensson and Garcia, 1993, cited in OECD SIDS 2007), although base respiration rate was unaffected. The reduction of soil pH following application of ammonium sulphate (in the absence of liming) is the main cause of toxic effect.
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.
