The N budget for Europe (excluding the former Soviet Union) indicates that the 3 principal driving forces of the acceleration of the European N cycle are fertilizer production (14 Mt (mill. tonnes) N yr−1), fossil fuel combustion and other industry (3.3 Mt N yr−1) and import...
Concerns the results of a feasibility study on the realisation of a nitrogen research programme for the local scale. This study, initiated by the Ministries of Housing, Physical Planning and Environment (VROM) and of Agriculture, Nature Management and Fisheries (LNV), was...
