Short description: In situ biotechnology for the upper 1 meter of the soil based on the enhanced natural biodegradative activity of the contaminated soil. Applied methods: agrotechnics and injection. 
Long description: Development of an in situ biotechnology based on the enhanced natural biodegradative activity of the contaminated soil. The enhancement of biodegradation happened in three consecutive steps: 1. Nutrient supply and aeration by frequent tillage of the upper 1 m to activate the indigenous microflora. 2. Injection of locally isolated and in the lab propagated bacteria to enhance biodegradation; 3. Injection of not indigenous microaerophyl bacterial inoculum from the market to enhance biodegradation in the loamy clods.
