            COMMISSION REGULATION (EU) No 1257/2014
of 24 November 2014
         
amending Regulation (EC) No 2003/2003 of the European Parliament and of the Council relating to fertilisers for the purposes of adapting Annexes I and IV
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EC) No 2003/2003 of the European Parliament and of the Council of 13 October 2003 relating to fertilisers (1), and in particular Article 31(1) and (3) thereof,

Whereas:







(1)


Crude potassium salts are materials obtained from natural resources through mining. For such natural products, the minimum nutrient content requirements set out in entry 1 of Table A.3 of Annex I to Regulation (EC) No 2003/2003 were laid down in accordance with sound industrial practice. However, when the potassium grade in the ore is naturally declining, producers encounter increasing difficulties to comply with the current limits, which jeopardies the continuous supply of fertilisers obtained from crude potassium salts to professional farmers. Therefore, these limits should be slightly reduced by amending entry 1 of Table A.3 of that Annex to allow producers to continue marketing their product as ‘EC fertiliser’. This amendment takes into account that the revised, slightly lower limit values also allow for efficient fertilisation and can therefore be considered as technical progress in accordance with Article 31(3) of Regulation (EC) No 2003/2003.












(2)


3,4–dimethyl-1H-pyrazole phosphate (hereinafter ‘DMPP’) is a nitrification inhibitor that is suitable for use with common nitrogen fertilisers (solid or fluid). DMPP reduces the risks of nitrogen losses into the soil and in the atmosphere and therefore enhances nitrogen use efficiency.












(3)


The reaction mixture between N-butyl-thiophosphoric-triamide and N-propyl-thiophosphoric-triamide (hereinafter ‘NBPT/NPPT’) is a urease inhibitor. NBPT/NPPT reduces the risk of nitrogen losses in the form of ammonia emissions after the application of urea-containing fertilisers and therefore enhances the nitrogen use efficiency.












(4)


In order to make them more widely available to farmers throughout the Union, DMPP and NBPT/NPPT should be added to the lists of authorised nitrification and urease inhibitors in Annex I to Regulation (EC) No 2003/2003 in accordance with Article 31(1) of Regulation (EC) No 2003/2003.












(5)


Solid or fluid straight urea formaldehyde fertilisers as well as solid NPK, NP and NK fertilisers containing urea formaldehyde are listed as fertiliser types in Annex I to Regulation (EC) No 2003/2003. Although urea formaldehyde condensates are stable in solution and in suspension, fluid NPK, NP and NK fertilisers containing urea formaldehyde are not yet listed in Annex I to Regulation (EC) No 2003/2003 as an individual product type. As there is a growing interest in marketing fluid NPK, NP and NK fertilisers containing a certain amount of urea formaldehyde as source of nitrogen, urea formaldehyde should be allowed in the preparation of fluid NPK, NP and NK fertilisers. Six new type designations should therefore be included in Table C.2 of Annex I to that Regulation.












(6)


Further to the inclusion of DMPP and NBPT/NPPT in Annex I to Regulation (EC) No 2003/2003, analytical methods to be applied for the official control of those fertilisers should be added to Annex IV to that Regulation.












(7)


Regulation (EC) No 2003/2003 should therefore be amended accordingly.












(8)


In order to ensure that the method for the analysis of NBPT/NPPT, which is currently under validation, is published by the European Committee for Standardisation before the addition of NBPT/NPPT in Annex I to Regulation (EC) No 2003/2003 and the new analytical method for that fertiliser type in its Annex IV, the application should be deferred as regards those amendments.












(9)


The measures provided for in this Regulation are in accordance with the opinion of the Committee established by Article 32 of Regulation (EC) No 2003/2003,





HAS ADOPTED THIS REGULATION:



Article 1
