Ecologists from RUDN University have studied abandoned vineyards and forests in Italy and found that a high concentration of nitrogen and carbon could be observed in the soil of an old oak forest left free from anthropogenic stress for about 200 years, while in the soils of vineyards abandoned relatively recently, the concentration is many times less. The data show that even Mediterranean soils, affected by humans, can accumulate large amounts of carbon and nitrogen in the process of changing the vegetation community. The article was published in the journal PLOS One.
