Techniques for rehabilitating polluted sites and soils - Summary sheets

The technique is based on adding compost to the soil to promote the biodegradation of pollutants (figure 9 ). It is based on three points:

• the need for structuring to improve soil aeration,

• the nutrient requirements of micro-organisms,

Compost varies enormously in quality, not all composts work in the same way, and some have specific actions. This technique is often used for hydrocarbon-contaminated soils.

• Principle
