Additional information
The effects of the Test item Algeafert Solid K+ on soil microbial nitrification (nitrogen turn-over) and carbon transformation (short-term respiration) processes were studied according to the OECD Guidelines 216 and 217, adopted 21th January 2000.
Test item was mixed into a sandy loam agricultural soil, at the application rates provided by the Sponsor: 116.28 mg of Algeafert Solid K+/Kg soil dryweight (low dose)and 232.56 mg of Algeafert Solid K+/Kg soil dry weight (high dose). The control consisted of soil treated with tap water and incubated at the same condition of the treated soil in the dark at 20±for 28 days. The Toxic reference item (Dinoseb acetate) was tested, for this soil batch, within a previous study to confirm the normal reaction of the soil against herbicides.
The influence of the Test item on the nitrification of lucerne meal was investigated and the results were compared to untreated samples.
The CO2produced by microbial soil microflora during short-term respiration trials, after addition of glucose, was measured and the results were compared to untreated samples.
The Test item Algeafert Solid K+, at the lowest dose applied and at the highest dose applied did not affect the microbial short-term respiration in soil since the treated samples deviated less than 25% from the control after 28 days (+0.9%for both low and high dose of the Test item).
The Test item,Algeafert Solid K+, at the lowest dose applied and at the highest dose applied did not affect the microbial nitrogen turn-over in soil since the treated samples deviated less than 25% from the control after 28 days (- 2.4%and+ 11.7%for the low and the high dose respectively).
According to the results of the present study, the Test item Algeafert Solid K+has no effects neither on carbon transformation nor on soil nitrification at the rates: 116.28 mg of Algeafert Solid K+/Kg soil dryweight (low dose) and 232.56 mg of Algeafert Solid K+/Kg soil dry weight (high dose).
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.
