摘要：For farmers it is very important to optimize the sizing of manure storage facilities depending on the size of livestock and agricultural land fertilization periods. Kept in farm manure should not affect the environment through direct pollution of surface waters. Also, storage areas must be accessible, easy to use and maintain. It should be emphasized that manure is not useless waste, these being considered very valuable manure used to fertilize not only plants, but also to improve soil structure. However, their inappropriate use can lead to contamination of groundwater by nitrates and ammonia emissions to air. Regarding the environmental impact of manure storage facilities there are two European directives that must be considered: Council Directive 91/676/EEC of 12 December 1991 concerning the protection of waters against pollution caused by nitrates from agricultural sources and Council Directive 96/61/EEC of 24 September 1996 concerning integrated pollution prevention and control. Council Directive 91/676/EEC of 12 December 1991 provides that Member States need to establish codes of good agricultural practice. In Romania, this directive is transposed by Order no. 1182 of 22 November 2005 on the Code of Good Agricultural Practice for the protection of waters against pollution caused by nitrates from agricultural sources. The implementation of this code by farmers is ob ligatory if they farm in areas declared vulnerable to nitrate pollution and voluntary, whether farmers have farms in non-vulnerable areas nitrates.
