Effects and implications
- Nitrogen deposition provides a fertilization effect on acid grasslands which are generally N limited.
- N deposition favours graminoids (grasses) at the expense of forbs and lower plants, especially where sites are surrounded by farmland.
- Nitrophilous grasses tend to shade out slower growing species.
- Nitrophilous grasses increase the amount of litter which falls on and shades out under-storey bryophytes (Berendse et al 1987).
