- EFFECTS OF NITROGEN CONTAINING FERTILISERS...
- Species Diversity
- Nitrogen rich soils
- Favour growth rapidly growing species
- Nettles
- Grasses
- Out-compete many other species
- Favour growth rapidly growing species
- Low soil nitrogen concentrations
- Hay meadows (eg) are allowed to survive
- Competitive species can survive (but not thrive)
- Reduces species diversity
- Nitrogen rich soils
- Leaching
- Nutrients are removed from the soil
- Rainwater dissolves soluble nutrients
- Nitrrate ions
- Carry them deep into soil - beyond plant roots
- Rainwater dissolves soluble nutrients
- Nitrate ions
- Find their way into watercourses
- Streams
- Rivers
- Fresh water lakes
- Harmful effects on humans, source of drinking water
- High concentrations of nitrate ions in drinking water
- Prevent efficient oxygen transport in babies
- Link to stomach cancer
- Harmful effects on humans, source of drinking water
- Can cause eutrophication on environment
- Find their way into watercourses
- Nutrients are removed from the soil
- Eutrophication
- Nutrient concentrations increase in bodies of water
- Natural process
- Freshwater lakes
- Lower reaches of streams
