A study suggests that the rising price of oil could soon make cereal crops grown with chemical fertilizers more expensive than those produced more naturally.
Industrial farming relies on fertilizers made from fossil fuels. These fertilizes are used to replace nutrients in the soil. Organic farming, however, improves soil fertility through crop rotations, and is therefore less affected by oil prices.
With oil predicted to reach $200 a barrel within five to 10 years, the profit margin on organic wheat, barley and oil seed rape could soon be significantly higher than for the same crops produced by non-organic methods.
