Nitrate-encumbered areas according to § 13aDüV

The nitrate backdrop according to § 13a DüV (2021) informs about all areas contaminated with nitrate, which were designated with the entry into force of the Bbg DüV (2022). In these designated areas, the deviating or supplementary requirements according to § 13a (2) DüV, § 1 Bbg DüV (2022) apply in principle. Areas with precipitation equal to 550 mm are presented separately in the present technical framework for the implementation of the requirements according to §13a (2) No. 7 of the Fertiliser Ordinance (DüV 2021). Requirements according to §13a (2) No. 7 of the Fertiliser Ordinance (DüV 2021): In crops with sowing or planting after 1 February, fertilisers with a significant nitrogen content may be applied only if an intermediate crop was cultivated on the affected area in the autumn of the previous year which was not broken before 15 January. This does not apply to areas where crops are harvested after 1 October and not areas in areas where long-term average annual rainfall is less than 550 millimetres per square metre. Further information on the Fertiliser Ordinance and the areas contaminated with nitrate are stored on the LELF page (https://lelf.brandenburg.de/lelf/de/landwirtschaft/acker-und-pflanzenbau/bodenschutz-und-duengung/).依据2021年版《肥料条例》（DüV）第13a条编制的硝酸盐污染区域背景资料，涵盖所有自2022年勃兰登堡州《肥料条例》（Bbg DüV）生效之日起被划定的受硝酸盐污染区域。在上述划定区域内，原则上适用《肥料条例》第13a条第2款、2022年勃兰登堡州《肥料条例》第1条规定的差异化或补充性要求。 针对落实2021年版《肥料条例》第13a条第2款第7项要求的本技术框架，将年降水量等于550毫米/平方米的区域单独列出。2021年版《肥料条例》第13a条第2款第7项规定：对于2月1日之后播种或定植的作物，仅当受影响区域在前一年秋季种植了填闲作物且该填闲作物未于1月15日前翻压时，方可施用高氮含量肥料。本规定不适用于10月1日后收获作物的区域，以及多年平均年降水量低于550毫米/平方米的区域。 更多关于《肥料条例》及硝酸盐污染区域的相关信息，可查阅勃兰登堡州环境与消费者保护局（LELF）官方页面：https://lelf.brandenburg.de/lelf/de/landwirtschaft/acker-und-pflanzenbau/bodenschutz-und-duengung/
