Description
Grassland is intensively used in the Netherlands. According to the fertilizer recommendation, the optimum N supply for such grassland is 250 kg ha-1 yr-1 for well-drained peat soils and 400 kg ha-1 yr-1 for all other soils. Environmental problems, associated with N losses from intensively used grassland, necessitate a refinement of the general recommendations. This, in turn, requires understanding of the dynamics of soil mineral nitrogen. This paper reports on (1) seasonal dynamics of soil mineral N and (2) seasonal variations in the response of cut swards to N. Results of grazed swards will be dealt with elsewhere (Oenema et al., in prep.).

Seasonal Variations in Soil Mineral Nitrogen and in the Response of Grassland to Nitrogen Fertilization
