【 摘 要 】

Artificial soils based on sand and clay contain multiple byproducts such as defecation precipitate and byproduct of wet magnetic separation (WMS). The organic portion is the sediment from the sludge lagoons of the pig farm. We have studied the moisture retention capacity of artificial soils. The moisture capacity is mainly contributed to by clay (28 mg/g), defecation precipitate (20 mg/g), and the sludge-lagoon sediments (30 mg/g). Specific surface area of artificial soils lies within a range of 50 to m2/g, which is close to ordinary chernozem soils. The obtained artificial-soil compositions can be used for land reclamation as an alternative substrate of natural soil.
