Organic fertilisers could reduce atmospheric CO2

Agricultural management systems based on organic fertiliser could contribute to the reduction of the amount of carbon dioxide in the atmosphere, according to the results of a study published in Nature magazine this week.

The study, carried out at the Rodale Institute in Pennsylvania, shows that the application of organic fertilisers in the major maize/soybean growing region of the USA could isolate an amount of carbon equivalent to 1-2% of the carbon released into the atmosphere from fossil fuel combustion in the USA. The study also shows that organic fertilisers provide the same yields as conventional mineral fertiliser systems and that they preserve carbon and nitrogen in the soil.
