Hydrological N export from tropical forests in the Congo Basin
Nitrogen (N) budgets in tropical African forests show higher N inputs than outputs, however forests paradoxically appear to tightly cycle soil N. We try to compare the magnitude and seasonality of aquatic N export from three different forest types in the Congo Basin...
Alternative fertilizers from nutrient-rich wastes for organic crops
A main challenge in optimizing organic crop production is the need to acquire alternative source of nutrients to satisfy the growing demand, and to reduce the conventional manure importation. In parallel, the production of organic wastes with high content of...
Nitrogen value of prunnings of Leucaena leucocephala (Lam.) deWit, Senna siamea (Lam.) Irwin & Barneby and Enterolopium cyclocarpum (Jacq.) Griseb.
Increasing pressure on land has led to development of many farming techniques for improved crop prooduction and yield. Plant prunning, an organic source of nitrogen for plant growth (Mund et al. 2016) has ben identified as a good alternative to inorganic fertiliser....
Communicating consequences of excess nitrogen – Short films for social media linking nitrogen and sustainable development goals
A good communication of complex environmental problems is essential to make a change. This communication should not only focus on policy makers,but also on citizens, as they are central for transformation processes.The problem of nitrogen excess is complex. Combining...
Citizen dialogue on policy instruments for the reduction of reactive nitrogen in Germany
The introduction into the topic of reactive nitrogen and the collection of ideas for mitigation was focus in the regional conferences. From every regional conference six volunteers were seent to the conference of delegates. There the most important measures were...
Nitrate Leaching Potential for Drip Irrigated Cauliflower
• Nitrate (NO3) contamination of groundwater is a significant unresolved environmental issue worldwide. Any Nitrogen (N) fertilizers not taken up by shallow rooted vegetable crops with high demand for N, such as Cauliflower (Brassica oleracea), can leach to the...
National Nitrogen Budget for Germany
Objectives – Key questions▪ National Nitrogen Budgets (NNB) aims to quantify sources and fate of reactive nitrogen (Nr).▪ How much Nr is introduced into the nitrogen cycle eachyear in Germany?▪ Where does this Nr come from and where does is go?▪ How reliable are the...
The US nitrogen footprint: An updated approach and comparison
The nitrogen footprint is a metric that connects resourceconsumption with the associated nitrogen loss to theenvironment In this poster, we present an improved approach for calculating the nitrogen footprint of food production. Our objectives are:• Update and improve...
Assessment of the efficiency of nitrogen removal from municipal wastewater
One of the biggest risks to surface waters is the deterioration of their quality as a result eutrophication. The main reason for eutrophication of waters is the local increase in population density, the increasing amount of municipal wastewater ( as well as the...
Nitrogen budget estimation in the East Europe: A case study for Dniester and Prut catchments
Agriculture, industry and other human activities have been altering Nitrogen ( cycling leading to N imbalance at ecosystem and regional levels. This results at numerous environmental impacts on air, water and soil quality, GHG balance and ecosystem functioning ENA,...
