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

Indicator: Agricultural nitrogen surplus

A graph shows the agricultural nitrogen surpluses for individual years and as rolling 5-year means between 1990 and 2022. The 5-year-mean nitrogen surpluses in kilogrammes per hectare dropped from 117 to 77. The target for 2028-32 is 70 kilogrammes per hectare and year.

The five-year average of nitrogen surplus of the total balance per hectare of utilized agricultural land has decreased by 34 % since 1992.The Federal Government aims to reduce the average nitrogen surplus of the total balance of the years 2028 to 2032 to 70 kilogrammes per hectare of agricultural land.If the trend of the last 10 years continues, the target will be reached. read more
