The use of iron (III) ferrocyanide soil amendment for removing salt from the soil surface

摘要

Accelerated soil salinization is a worldwide concern. Our study was carried out to determine the effects of different rates (0, 5, 10, and 15 mmol kg(-1)) of iron (III) ferrocyanide application to remove salts from the soil. Within two weeks of its application, iron (III) ferrocyanide at 5, 10, and 15 mmol kg(-1) removed 12.2%, 26.5%, and 42.9% of the total salts from the soil, respectively. Results suggested that iron (III) ferrocyanide application at 15 mmol kg(-1) is one of the most rapid and effective ways to remove substantial amounts of salts from undrained soil (land) where fresh water is scarce.
