PROCESS FOR THE DISPOSAL OF SEMI-LIQUID MANURE FROM A GIANT FARM OF DOMESTIC ANIMALS, PARTICULARLY PIGS, CATTLE AND POULTRY

摘要

The invention relates to a process for treating manure, in which the thixotropic properties of the manure are modified by addition of calcium or magnesium lignosulphonate containing hemicelluloses and sugar and the manure prepared in this way and partially deodorised is applied in several aliquots to an organic or inorganic absorbent which is thoroughly mixed and aerated between the individual aliquot additions. After applying the desired amount of manure, the resulting mixture is enriched with substances favourably influencing plant growth, and this mixture is used as a controlled-release fertiliser, consisting of (by weight) 10 to 50 parts of shredded waste based on plant biomass, 30 to 60 parts of manure prepared using 1 to 20 parts of calcium or magnesium lignosulphonate, 0 to 40 parts of limestone, 0 to 20 parts of ammonium sulphate and 0 to 20 parts of phosphates.
