Food production

Growing plants to eat is one of the simplest ways to produce food. We can apply our knowledge and understanding of biology to make even this simple process more efficient and productive.

This could involve improving the quality of the soil and the productivity of plants or reducing losses due to pests and diseases or in storage. Sustainability is also important in food production – the methods we use must be useful for more than a few seasons, but for many generations to come. Sustainability includes reducing the carbon footprint of our farming methods.

Experiment topics

  • Investigating the effects of biochar on soil fertility

    Research suggests that biochar is a soil improver that also acts as a carbon store. Assess the effect of biochar on the growth of seedlings and evaluate the methods used.

  • Investigating what makes fruit go brown

    Observe cut and crushed apple or potato turning brown. Test hypotheses to explain the reaction. Apply results to commercial food processing and suggest how to prevent or slow down browning.
