In addition to sufficient water, plants need nutrients (e.g., nitrogen, phosphate, potassium) and trace elements (e.g., copper and zinc) to develop and grow. Only then can they achieve high yields of good quality. Plants absorb nutrients and trace elements from the soil through their root system. The humus content of the soil plays a central role in this process. Humus is rich in plant nutrients a... read more

Nitrogen is an essential nutrient for all living organisms. The use of mineral and organic nitrogen fertilizers to increase yields is therefore common practice in agriculture. Careful and needs-based application is crucial. Excess nitrogen can pollute water and land ecosystems and adversely affect the climate, air quality, and biodiversity. read more

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

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

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

The averaged index of air pollutants fell by 39.5 % between 2005 and 2023.The obligations of the Gothenburg Protocol and the NEC Directive for 2020 were achieved.The challenge to meet the reduction commitments of the European NEC Directive for 2030 differ from substance to substance.Nitrogen oxide emissions need to be reduced significantly to achieve the 2030 goal.For sulphur dioxide, ammonia and... read more
