Timing subsurface drainage (SD) at two critical periods to coincide with melting of frozen soil water and the rainy season may effectively lower the groundwater table and increase the leaching of salts. A field experiment was set up in the eastern coastal saline area of Hebei Province, China, to assess the effects of SD on soil water and salinity. Subsurface drainage significantly prevented the rise...
Improvement of saline-alkali soils by biological means is a strategic soil conservation method. To investigate the capacity of oat for phytoremediation, two factor randomized block design experiments are carried out in coastal North China. The two factors — oat variety (“Ba You-1” – BU, “Hua Zao-2” – HZ and “Bai Yan-2” – BY) and soil salinity (1.0, 2.0 and 3.0gkg −1 ) — are analyzed for oat...
