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…
Bottom-up uncertainty estimate of global ammonia emissions from global agricultural production systems
n this paper we describe differences in the uncertainty of NH 3 emissions from agriculture and the major factors determining the uncertainty between countries and world regions, i.e. the USA, the…
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…
The consequences of interpolating or calculating first on the simulation of pesticide leaching at the regional scale
Models for calculating pesticide leaching require soil data, which is collected at drilling points. This article describes how this information can be interpolated to maps on the national scale and…
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…
Mapping Ground Water Vulnerability to Pesticide Leaching
To monitor the progress of the EU Thematic Strategy on the Sustainable Use of Pesticides, the Netherlands Environmental Assessment Agency (MNP) has developed a simple pesticide leaching indicator…
