Division F Nitrification and urease inhibitorsF1
The urease and nitrification inhibitors listed in the Tables F.1. and F.2. below may be added to the nitrogenous fertilisers types listed in Sections A.1., B.1., B.2., B.3., C.1. and C.2. of Annex I subject to the following provisions:
- (1)
at least 50 % of the total nitrogen content of the fertiliser consists of the nitrogen forms specified in column 3;
- (2)
they do not belong to the fertiliser types mentioned in column 4.
Fertilisers to which a nitrification inhibitor listed in Table F.1. has been added shall have the words ‘with nitrification inhibitor ([type designation of nitrification inhibitor])’ added to their type designation.
Fertilisers to which a urease inhibitor listed in Table F.2. has been added shall have the words ‘with urease inhibitor ([type designation of urease inhibitor])’ added to their type designation.
Technical information, as complete as possible, must be provided with each package or bulk consignment by the person responsible for marketing. This information must enable the user in particular to determine the rates and timing of application in relation to the crop being grown.
New nitrification inhibitors or urease inhibitors may be included in the Tables F1 or F2 respectively after evaluation of the technical files submitted in accordance with guidelines to be elaborated for these compounds.
