5.1 describe how glasshouses and polythene tunnels can be used to increase the yield of certain crops
In a greenhouse you can control factors such as heat moisture, you can set these factors to best suit a particular crop. This optimization of environmental variables should result in a better yield of a particular crop.
- Protect the crops from the environment
- Temperature
- Water levels
- Fertilizers
- Carbon Dioxide levels
- all controlled to maximise yield
