From forest to waste: assessment of the Brazilian soybean chain, using nitrogen as a marker

With economic growth, urbanization and changing diets, world demand for plant-derived oils and their derivates is soaring. Oils are used inter alia in the food, feed and cosmetics industry, and…

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…

Exploring changes in world ruminant production systems

In the past 30 years world production of ruminant meat and milk has increased by about 40%, while the global area of grassland has increased by only 4%. This is because most of the increase in…

The Dutch nitrogen cascade in the European perspective

This paper provides an overview of the origin and the fate of nitrogen in the Netherlands, the various reported impacts of nitrogen, the Dutch and European policies to reduce nitrogen emissions and…

Environmental effects of manure policy options in the Netherlands
