Reactive nitrogen

Annual nitrogen inputs into the German environment – sectoral percentages of total inputs 1995-2014

Reactive nitrogen, unlike nonreactive molecular nitrogen (N2), is in a great many organic and inorganic substance compounds and of vital importance to all life processes. The availability of reactive nitrogen often limits plant growth, which is why sufficient supply of reactive nitrogen is so important in food production. If excessive amounts of reactive nitrogen are deposited to the environment,... read more

Fertilizer

In order to develop and grow, apart from adequate water, plants need nutrients such as nitrogen, phosphate and potassium and trace elements such as copper and zinc. Only if these requirements are met can high yield, high quality crops be obtained. Crop plants obtain nutrients and trace elements from the soil via their root systems, a process in which soil humus content plays an instrumental role.... read more

Environment and agriculture – Overview for Germany

Ein Feld mit Gräsern und Blüten

More than half of Germany's surface area is used for agriculture. Agriculture thus is the largest land user in Germany and a significant contributor to environmental stress. On the other hand, agriculture is also affected, for example, by the effects of climate change. In the flyer "Environment and agriculture 2018" UBA presents key facts about agriculture and environment. read more

Nitrogen

In as much as nitrogen is an indispensable nutrient for all living things, the use of mineral and organic nitrogen fertilizers to increase crop yields is a common practice. It is essential that such fertilizer be used judiciously and on a needs oriented basis. Nitrogen surpluses can damage terrestrial and aquatic ecosystems and can have harmful climatic, air quality, and biodiversity effects. read more

Ammonia, dust and odour emissions

Intensive livestock farming is a key agricultural sector in Germany, but one that unfortunately generates ammonia emissions, odours and dust that are hazardous to the environment and a nuisance to persons living in close proximity to livestock farms. read more

Umwelt-Indikator

Indicator: Emission of air pollutants

Graph: The development of emissions of five air pollutants and an overall index relative to the base year 2005 (=100%) can be seen. All values decrease significantly between 2005 and 2021, but ammonia only since 2014. The 2030 target (55%) seems within reach.

The averaged index of air pollutants fell by 34.1% between 2005 and 2021.The obligations of the Gothenburg Protocol and the NEC Directive for 2020 were achieved.Safely meeting the commitments of the European NEC) Directive for 2030, is a challenge for the German environmental policy.Ammonia emissions must continue to be significantly reduced to achieve this. read more
