Nutrient Cycles: Fertilisers and Eutrophication

Use of natural and artificial fertilisers is employed to replenish nitrates and phosphates lost during plant harvesting and livestock removal.
There are environmental issues associated with fertiliser use, such as leaching and eutrophication.
Practice answering exam-style questions on the topic to understand the logical order, such as how nitrate from fertiliser leads to increased algae and reduced light.
