# Commission Regulation (EC) No 205/2009 of 16 March 2009 approving minor amendments to the specification for a name entered in the register of protected designations of origin and protected geographical indications (Riso Nano Vialone Veronese (PGI)), Division 4.6: Link:

Extent: E+W+S+N.I.

Riso Vialone Nano Veronese can be produced in the defined area because it has a uniform climate. The freshness and purity of spring water, fairly typical of the area, help make this possible. In these areas, crop rotation is used in rice growing, considerably reducing the use of plant protection products and chemical fertilisers.
The characteristics of the soil found in the Verona area differ from those of other rice-growing areas due to:
the soil pH, which is always alkaline;
the spring water coming from calcareous rock and, therefore, also alkaline;
the cultivation traditions which continue to maintain the rice-growing heritage.
