- Abstract
The Julius Kühn Institute has published a handbook for calculating the nitrogen balance in agriculture in Germany from 1990 to 2019. The handbook covers various balance positions such as mineral fertilizers, organic fertilizers, livestock manure, and feed. The results show the development of nitrogen inputs and outputs during this period. The handbook describes the methodology for calculating nitrogen balances and discusses uncertainties in the quantity structure and coefficients. It also explains how nitrogen accounting is used in different areas to assess the impact of nitrogen on humans and the environment. The article provides information on feed imports and exports as well as various feeds and their import quantities to Germany. It provides quantities for various types of grains, legumes, oilseeds, cassava, dry forage, bran, oil cakes and meal, dry chips, by-products of corn processing, potato pulp, animal feed, and atmospheric deposition of nitrogen compounds. Agriculture contributes only marginally to the atmospheric deposition of nitrogen compounds. It also provides information on various agricultural products and their nutrient contents. The table shows the cultivation and harvest quantities of various vegetable and fruit varieties in Germany. The article also describes the use of plant products and animal manure in biogas plants in agriculture. The total nitrogen balance of agriculture in Germany for the year 2019 shows an excess of 78.9 kg N/ha LF. It is noted that both inputs and outputs undergo annual fluctuations. The excess of the overall balance from 1992 to 2019 has decreased by 17 kg N/ha or 16%. There are uncertainties in the data, but the errors of the individual balance variables remain mostly constant. The article also includes references to further reports and studies on the topic of nitrogen deposition in the environment. The table presented shows the nitrogen balance of agriculture in Germany from 1990 to 2019. It lists various categories of feed and market products, as well as nitrogen inputs, fertilizers, emissions, and other factors. The data shows that the nitrogen surplus varied from 1990 to 2019, with the highest surplus recorded in 1991 and the lowest in 2019. The nitrogen input from fertilizers and the nitrogen output from plant market products are also listed. It should be noted that the data is partially preliminary. The article includes a number of tables with data on various agricultural products and imports in Germany. It provides information on feed, vegetables, fruits, animal products, biogas and bio-waste plants, mineral fertilizers, and agricultural land areas. The tables show quantity information for various years and also indicate uncertainties and errors in the data. The data basis is partially preliminary.
