PROCESS FOR OBTAINING A FERTILIZER COMPOSITION COMPRISING A DMPSA NITRIFICATION INHIBITOR VIA ADDING DMPSA SALTS INTO THE FERTILIZER MELT

Process for obtaining a fertilizer composition comprising(i) at least one nitrogen-containing fertilizer (F); and(ii) a nitrification inhibitor (N) selected from the group consisting of 2-(3,4-dimethyl-1H-pyrazol-1-yl)succinic acid and/or 2-(4,5-dimethyl-1H-pyrazol-1-yl)succinic acidcomprising the s...

Summary:Process for obtaining a fertilizer composition comprising(i) at least one nitrogen-containing fertilizer (F); and(ii) a nitrification inhibitor (N) selected from the group consisting of 2-(3,4-dimethyl-1H-pyrazol-1-yl)succinic acid and/or 2-(4,5-dimethyl-1H-pyrazol-1-yl)succinic acidcomprising the steps:a) melting fertilizer (F), and/or providing a melt of fertilizer (F), andb) adding the nitrification inhibitor (N) to the melt of fertilizer (F), whereinthe residence time of the nitrification inhibitor (N) in the melt of the nitrogen-containing fertilizer (F) is not more than 5 minutes.
