What do Fertilisers contain and what do they do?
Fertilisers contain minerals such as nitrogen, potassium and phosphorus, which help plants to grow. Fertilisers increase crop yields but cause the problem of 'eutrophication' when they're washed by rainwater into rivers and lakes. Most chemical fertilisers are made by the reaction of an acid with an alkali.
