Compositions for and method of degrading organic chemicals in soil. The composition is a nutrient medium serving as a substrate for micro-organisms in the soil, preferably containing a major proportion of a source of carbon skeleton and energy, a macronutrient component preferably including nitrogen and other macronutrients, and a micronutrient component, preferably also a complexing agent and a vitamin/co-factor component. This nutrient material is added to soil, e.g. soil contaminated by a pesticide, to cause proliferation of micro-organisms which are effective, or which develop effectiveness to degrade the organic chemicals. Preferably the micro-organisms are those naturally present in the soil but useful micro-organisms may be added with the nutrient medium. |
