Increasing Crop Yield

                INCREASING CROP YIELD

-          Keeping plants enclosed in glasshouses keeps them free from pests and diseases

-          Commercial farmers often supply artificial light after the sun goes down so photosynthesis can go on for longer

-          Glasshouses trap the suns heat to keep the plants warm. In the winter, farmers install heaters to keep the temperature at an ideal level

-          Farmers also increase CO2 levels by using a paraffin heater. When the paraffin burns, CO2 is released as a by product

-          By increasing the temperature, CO2 levels and light intensity, farmers can increase the rate of photosynthesis, which means the plants grow faster and bigger – and crop yields will be higher

FERTILISERS

-          Plants need certain elements, e.g. nitrogen, potassium…
