Towards Sustainability

From the "Sole 24 ore" Thursday 24th of May 2007:
A recent study of IBIMET Italian Biometeorological center of CNR in Florence has concluded that in order to maximise the CO2 absorbtion from the atmosphere, the good agricoltural practice has to incorporate as much cultivation residues as possible: this goal can be achieved using intercropping, that allow the soil to stay protected at all times by a vegetating layer, performing shallow tillings to avoid contact between organic matter and open air. This also allows to use less fertilizers.
The data shows, that with an increase of 1% of organic matter, a Ton of CO2 can be permanently sequestered, if this result was to be applied to half of the arable lands in Italy, 50% of the total emissions could be sequestered.
