Soil Washing Geoengineer

Jan 29, 2013  Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine grained soils (silts and ...

Aluminum in soil: avoiding aluminum toxicity

Aluminum is one of the most abundant elements on the planet: roughly 7% of the earth’s mass is made up of aluminum. Non-essential for plant growth, available or soluble aluminum can be toxic to plants, whereas other forms—such as aluminosilicates and precipitates, or forms of this elemental metal bound up in ligands—are decidedly not phytotoxic.
