Early fertilization and absorbent treatments continuously enhanced windbreak tree growth and soil properties in the Hetao Plain of Inner Mongolia, China

다국어 초록 (Multilingual Abstract)

Intensive and continuous management has rarely been applied in forestation designed to combat desertification, except for afew instances of fertilization and irrigation in the early stage in northern China. We hypothesized that early and discontinuousfertilization and absorbent treatments would continuously increase tree growth and improve soil properties in an aridregion. In 2003 and 2004, treatments of nitrogen fertilization and absorbents were applied to Populus alba var. pyramidalistrees in an experimental windbreak site in the Hetao Plain of Inner Mongolia, China. Nevertheless, the current study resultshave demonstrated that early and discontinuous nitrogen fertilization and absorbent treatments continuously increased treegrowth (2003–2009) without any significant improvement in soil properties in 2010. The study results suggest that earlyand discontinuous fertilization and absorbent practices may be sufficiently effective in forestation aimed at combatingdesertification in arid lands where continuous maintenance cannot be expected.
