Arriva il gabinetto per le mucche: il primo dispositivo di questo tipo in Svizzera è entrato in funzione in una fattoria di Hellbühl (LU), dove è stato presentato mercoledì. Lo scopo è ecologico e olfattivo: il sistema impedisce il mescolamento di urina e feci, con conseguente riduzione delle emissioni di ammoniaca.
Concretamente gli animali vengono attirati nella “toilette” - una postazione protetta da sbarre - dove vengono poi stimolati fra le mammelle e la vulva, in modo da urinare: l’urina viene raccolta in una bacinella e pompata all’esterno. Viene poi conservata separatamente e utilizzata come fertilizzante naturale a base di azoto.
Il dispositivo è pensato per limitare la dispersione di ammoniaca
L’iniziativa, che comprende altre misure, fa parte del progetto “Ammoniak und Geruch Zentralschweiz” (Ammoniaca e odore della Svizzera centrale) ed è sostenuta dall’associazione lucernese dei contadini e da diverse altre istituzioni. Nell’ambito dello stesso approccio nel marzo 2024 era stato presentato a Ufhusen (LU) un porcile modello.
L'agricoltura vuole ridurre la dispersione di azoto
