HUT048186 T A compsn. rich in bioactive cpds. for reactivation of barren, poor or damaged land, contains 0.6-3% of a biomass-grown on at 20-40 deg.C of a microflora-fauna culture taken from a corresponding meadow land, of microorganisms living on it, fresh or decayed organic matter, of untreated grain, woodland topsoil and water. - 20-60 wt.% of a nitrogen, phosphate and potassium fertiliser and 30-70 wt.% fresh or decayed organic matter. The compsn. is applied at a rate of 1-5 ton/hectare and is washed into neutral or nearly neutralised soil. Following this 200-400 kg/ha untreated seed is sown in the spring or autumn. The tpe of annual seed chosen depends on local climatic conditions. When the plants start to shoot up the soil is surface treated by 60-80 kg/ha fertiliser and/or by 0.2-2 t/ha compsn., followed by working the green vegetation in the topsoil. The thus treated soil is allowed to rest for two weeks and/or is allowed to mature before cultivation starts.
