Increasing anthropogenic nitrogen inputs and riverine DIN exports from the Changjiang River basin
Our result indicates that anthropogenically enhanced N inputs dominate and will continue to dominate river DIN yields under changing human pressures in the basin. Therefore, nitrogen pollution is and…
Progress in the modelling of critical thresholds, impacts on plant species diversity and ecosystem services in Europe. CCE Status report 2009
The CCE Status Report 2009 demonstrates that effects of nitrogen deposition are interrelated with the change of climate and biodiversity. The report proposes indicators, modelling methodologies and…
Global nitrogen and phosphate in urban wastewater for the period 1970 to 2050
This paper constitutes the first spatially explicit, global assessment of sewage N and P emissions to surface water for the period 1970 to 2000, and the first projection of such N and P emissions for…
Global patterns of dissolved silica export to the coastal zone: Results from a spatially explicit global model
This study presents a model for river export of dissolved SiO 2 , with river-basin spatial scale and an annual temporal scale. The model is based on four variables with a significant influence on DSi…
A framework to identify appropriate spatial and temporal scales for modeling N flows from watersheds
Many different large-scalewatershed nitrogen (N) flowmodels exist, which describe processes related to the horizontal movement of N through large drainage networks of river basins. Equations of such…
Permissible manure and fertilizer use in dairy farming systems on sandy soils in The Netherlands to comply with the Nitrates Directive target
Based on experimental data, this study explores the limits on the use of cattle slurry and mineral fertilizer in grass and silage maize. Cut grasslands can utilize cattle slurry up to 340 kg nitrogen…
Permissible manure and fertilizer use in dairy farming systems on sandy soils in The Netherlands to comply with the Nitrates Directive target
From the point of view of N leaching and P accumulation, manure rates should be determined by (i) the harvest regime of the grass, (ii) the proportions of grass and maize in the farm area and the way…
Interim evaluation of the Dutch crop protection policy
Crop protection methods in the Netherlands have become more sustainable since 1998 as a result of efforts made by growers. However, at the moment the environmental quality of surface waters does not…
Interim Evaluation of the Policy Document On Sustainable Crop Protection
Crop protection methods in the Netherlands have become more sustainable since 1998 as a result of efforts made by growers. However, at the moment the environmental quality of surface waters does not…
