Amelioration of sandy soils - opportunities for long term improvement

To investigate amelioration options for sands that have low water holding capacity, low organic matter, low nutrient availability, compaction, non wetting and high risk for wind erosion.本研究旨在针对持水能力 (water holding capacity) 低下、有机质 (organic matter) 匮乏、养分有效性 (nutrient availability) 不足、存在压实 (compaction) 问题、具有斥水性 (non-wetting) 且风蚀 (wind erosion) 风险较高的沙土，探究其改良方案。
