Abstract

The invention relates to a simplified method for biologically cleaning almost any-sized area of soil which is contaminated with mineral oil-based hydrocarbons (MHC), and especially the leftover pollutants associated with mineral oil-based hydrocarbons. According to said method, the contaminated soil is treated with concentrated nutrients to stimulate and help the growth of MHC-consuming micro-organisms so that they can be cultivated and reproduce more quickly. The inventive method is characterised in that it is particularly easy to carry out and in that after a) advance dampening/watering if necessary, b1) the soil being cleaned is broken up to a considerable depth in at least one process, b2) the concentrated nutrients are added in the form of an aqueously dilute emulsion and/or dispersion, said concentrates being sprayed essentially evenly, also in at least one process, and c) the soil is then thoroughly re-watered. Steps b1) and b2) can be carried out once or repeatedly. The following sequences are preferable: (b1)=>(b2); (b2)=>(b1); (b1)=>(b2)=>(b1) or (b2)=>(b1)=>(b2).
