New method to fight desertification

  • Chinese scientists have claimed to have converted sand into fertile soil using a new method which they hope will be useful to fight desertification.
  • A team of researchers from Chongqing Jiaotong University has developed a paste made of plant cellulose that, when added to sand, helps it retain water, nutrients and air.
  • The plants in the sandy test plot needed about the same amount of water as those grown in regular soil, but required less fertilizer and bore higher yields, according to estimates by experts.
  • Since 2013, scientists have been experimenting with outdoor cultivation at two sites with areas of approximately 550 and 420 square metres in Chongqing, where scientists simulated desert landform conditions.
