Increasing Food Production

Fertilisers

Fertilisers are chemicals that increase crop yields by providing minerals that plants need to grow e.g. nitrate and potassium. Minerals in the soil are used up for crops to grow and the fertilisers replace this so the next crop can grow. 

• Natural Fertilisers: Organic, manure.
• Artificial Fertilisers: Inorganic, powders.
