L'organic agriculture, better known as "biological“, It may not be as healthy as believed to date. We of the editorial staff of IdeasGreen we always recommend buying fruit and vegetables from small local producers who, while not holding the organic brand, are able to provide the public with more wholesome food. Even better if you have a small patch of land available, at this point the vegetables could be self-produced!
Recent research reveals that biological food it doesn't hurt, but it doesn't do any more good than conventional ones either. L'beneficial impact which has theorganic agriculture on humans, it does not lie in the wholesomeness of the products collected, rather inenvironment. L'biological agriculture it appears to be much more climate-friendly than conventional.
These are not intuitive predictions but an accurate study conducted by the Swiss Andreas Gattiner, of the Research Institute onorganic agriculture by Frick; the study was published on PNAS. Gattinger, together with his research team, compared 74 studies concerning soil carbon content in cultivated fields in con biological agriculture and in fields cultivated with industrial agriculture.
Thanks to the amount of data, the researchers of the Frick Institute were able to carry out a detailed and precise comparison, that is, with the same crops and ecological and environmental conditions. The result saw that the land exploited for thebiological agriculture it had on average 3.4 tons of organic carbon per hectare more than industrially cultivated agricultural land and therefore, with the massive use of inorganic fertilizers.
Carbon continues to accumulate over time in the land intended fororganic agriculture at the rate of 450 kilograms of carbon dioxide equivalent per hectare each year.
What does it mean that organic carbon is found in the soil of organic farming?
It means that the carbon is absorbed and fixed by subtracting harmful emissions to the atmosphere. In Italy there is about one million hectares of land cultivated with biological agriculture, in them about one thousandth of the CO2 emissions that our country produces in one year.
