The reason of soil acidification

15/09/2015

     Australian and Chinese scientists have made significant progress in determining what causes soil acidification – a discovery that could assist in turning back the clock on degraded croplands.      Accordingly, the scientists of James Cook University (JCU) examined a massive 3600 km transect of land in China, stretching from the country’s sub-arctic north to its central deserts. The work yielded a new advance that describes the mechanisms involved in soils becoming acidified. Also, soil degradation is a critical problem confronting humanity, particularly in parts of the world such as the tropics where land use pressure is increasing and the climate is changing.          Dr Nelson of JCU said the research found different drivers of soil acidification processes in different types of soil across northern China. “This information is vital for designing strategies that prevent or reverse soil acidification and to help land managers tailor their practices to maintain or improve soil quality,” he said.      The new advance is potential to deliver practical benefits to farmers and land managers, working in diverse environments. Acidification is one of the main soil degradation issues worldwide, accelerated by water leaching through the soil. It is related mostly to climate, and the overuse of nitrogen-based fertiliser.
