Effects of seawater irrigation on soil safety and crop yield in coastal semi-arid area
滨海半干旱地区海水灌溉对土壤安全和作物产量的影响

Seawater irrigation has recently emerged and plays important roles in saving freshwater resources and promoting agriculture production in the coastal semi-arid areas of North China Plain. From 2001 to 2003, field experiments were conducted to study the effects of seawater irrigation on soil safety and crop yield in Laizhou county, Shangdong province.
