The soil regenerating composition is of the type including at least one clay related to zeolites, benthonites and/or vermiculites, an organic material selected amongst organic materials of plant origin, organic materials or animal origin and mixtures thereof, and at least one agriculturaly acceptable cation. The composition is characterized in that said clay or the mixture of said clay must meet the following double condition: an internal surface higher than 100 m<2>/g; a cationic exchange capacity higher than 80 milliequivalents/100g of dry product, and in that said organic material has an enzymatic activity such that in one hour one dry compost gramme produces more than 1000 microgrammes of p-nitrophenol from p-nitrophenyl phosphate.
