Opening Sessions

2b, 4a, 5a – Nitrification and Inhibitors

1b. Responsible consumption and production and feedbacks in the N cycle

Assessing future nitrogen fertilizer demand

Assessing future nitrogen fertilizer demand

Inefficiencies in global cropland nitrogen use have led to the dissemination of reactive nitrogen throughout the hydrosphere. Assessing the future N input requirements and N use in agriculture for the five shared...

Influence of soil properties on N2O emissions

Influence of soil properties on N2O emissions

Observations on nitrous oxide (N2O) from urine and dung patches deposited by grazing cattle in sub-Saharan Africa (SSA) are scarce. Moreover, the effects of soil properties (e.g. pH or texture) on N2O emissions from...

2b. Optimizing the efficiency of nitrogen use in crop production

Sustainable plant nutrition and nitrogen

Sustainable plant nutrition and nitrogen

The theme of sustainable plant nutrition is important to the sustainable management of nitrogen. The crop nutrition industry has played a large role in enhancing the earth’s capacity to support human life. Since 1960,...

3b. Reduction of nitrogen in wastewater

Regional nitrogen soil surface budgets Germany

Regional nitrogen soil surface budgets Germany

Results of the nitrogen (N) soil surface balances for the districts in Germany for the period 1995 to 2017 are presented. Biogas production and transfer of manure between districts are considered in the budget scheme....

Sources of nitrogen in rivers worldwide

Sources of nitrogen in rivers worldwide

We analyse sources of nitrogen (N) in rivers worldwide in a spatially explicit way. For this, we link three global models. Today, many rivers are polluted. Over half of global N in rivers is from anthropogenic sources...

Nitrogen Balance of Latvia

Nitrogen Balance of Latvia

The evaluation of nitrogen balance at country level is one of key steps to responsible and effective nitrogen management system development and adoption of reactive nitrogen loss mitigation system. The nitrogen balance...

National nitrogen flows in Germany

National nitrogen flows in Germany

Emissions of reactive nitrogen (Nr) cause a bundle of severe environmental damages. For the development of remediation measures it is necessary to quantify sources, sinks and flows of Nr. Therefore the National...

Is Nitrogen the Next Carbon?

Is Nitrogen the Next Carbon?

  Just as carbon fueled the Industrial Revolution, nitrogen has fueled an Agricultural Revolution. The use of synthetic nitrogen fertilizers and the cultivation of nitrogen-fixing crops both expanded exponentially...

The global nitrogen cycle from 1965 to 2010

The global nitrogen cycle from 1965 to 2010

  Here we provide cross-sectoral nitrogen budgets for the period 1965-2010 for 212 countries, including sub-budgets for croplands, pastures, natural vegetation, livestock systems, the food supply chain,...

6a. Closing the N cycle innovations for sustainable N management

7a. From Science to Policy

Nr management in current Brazilian policies

Nr management in current Brazilian policies

Emissions of reactive nitrogen (Nr) have increased in Brazil from 1990 to 2015, mainly due to the enhancement of nitrogen input from human activities in the country. In this paper, we present a survey of existing...

7b. Educational aspects, public awareness, risk communication

The first global nitrogen policy database

The first global nitrogen policy database

Calls to address nitrogen pollution are gaining traction in the policy world. However, there is little understanding of the nitrogen policy landscape across different countries. This study introduces the first global...

A national nitrogen target for Germany

A national nitrogen target for Germany

The complex nature of the nitrogen cycle hampers public awareness of the nitrogen problem. To overcome this issue and to enhance public awareness and the sensitivity for policy action, we developed a new, impact-based...

Special Session on Nitrogen Footprints

Nitrogen footprint of protein-free products

Nitrogen footprint of protein-free products

The N footprint is an indicator of N loads from individual consumption of food as well as energy. A bottom-up approach, N-calculator method, calculates the food N footprint using the N content in consumed foods, such...
