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…
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…
Denitritication across landscapes and waterscapes: a synthesis
Both newly fixed N and recycled N (e.g., manure) are processed by terrestrial ecosystems. A substantial portion of this recycled N is subsequently transferred to groundwater, wetlands, lakes, rivers…
Nitrate leaching in agriculture to upper groundwater in the sandy regions of the Netherlands during the 1992-1995 period
The Dutch National Monitoring Programme for Effectiveness of the Minerals Policy (LMM) was initiated to allow detection of a statutory reduction in nitrate leaching caused by a decreasing N load. The…
Environmental effects of manure policy options in the Netherlands
This study explores the effects of manure policy options for agricultural land in The Netherlands on nitrate leaching to groundwater, ammonia and nitrous oxide emissions to the atmosphere and on…
Economic and environmental effects of the manure policy in the Netherlands: synthesis of integrated ex-post and ex-ante evaluation
This paper summarises the results of both an ex-post evaluation of the Dutch Mineral Accounting System (MINAS) and an ex-ante evaluation of the effect of different levy-free surplus values.
The integrated modeling system STONE for calculating nutrient emissions from agriculture in the Netherlands
For the Netherlands, a nutrient emission modeling system, called STONE, has been developed. It was designed for evaluation at the national and regional scale of the effects of changes in the…
