- Improving Productivity
- Primary
- Light levels
- Grown under light
- Water levels
- Irrigating-crops
- Drought resistant strains
- Temperature
- Greenhouses
- Planting early to provide a longer growing season
- Nutrient levels
- Crop rotation
- Fertiliser
- Competition with pests
- Spraying with perticides
- Breeding pest resisant strains
- Remove biomass & lower yield
- Fungicides
- Prevents fungal diseases
- Herbicides
- Competition from weeds
- Light levels
- Secondary
- Transfer of energy from primary to secondary is low
- Not every part of the plant is eaten or digested
- Much of the energy stored after consumption is not transferred to growth
- This must be manipulated in order to maximise energy transfer
- Harvest animals just before adulthood
- Steroid use to increase growth rate
- Selective breeding
- Treatment with antibiotics
- Zero grazing stops loss of energy by movement
- Consider animal welfare issues
- Transfer of energy from primary to secondary is low
- Primary
