| UNIQUE FEATURES: |
|
- Adjusts pH value and prevent ammonium
- Can react with contaminant metals either to form
immobile precipitants or to mobilize other metals to permit
remediation
- Enhances microbial metabolism to remediate Pollutants
- Helps the root zone breathe well.
- Provides a long-term oxygen reservoir, releasing oxygen
relatively slowly
- Provides calcium which is necessary for plants' growth
- Stops anaerobes to proliferate
