When a virgin field is tilled and then fertilized with synthetic fertilizers, it will lose between 50 and 65 percent of its nitrogen and soil carbon over fifty years.Â
When a virgin field is tilled and then fertilized with synthetic fertilizers, it will lose between 50 and 65 percent of its nitrogen and soil carbon over fifty years.
Organic farming has a different philosophy. It sees farmers as stewards of the land, harvesting its fruits while they care for it
The scientists concluded that the productivity of the organic farm was being maintained, while that of the conventional farm was being reduced because of high rates of soil erosion.
Conventional agriculture relies heavily on synthetic fertilizers, especially nitrogen.
Half to two-thirds of this nitrogen makes its way into rivers and other ecosystems, affecting both freshwater and marine environments.
Organic farms do not use synthetic fertilizers, the manufacture of which requires a lot of energy.
Food and Rural Affairs, organic crops used 35 percent less energy per unit of production and organic dairying 74 percent less.
