Method for the manufacture of fodder and/or soil improving agents from waste material

A method for the manufacture of fodder, and/or soil improving agents from waste material comprising harvesting environmentally disturbing aquatic plants and mixing the pieces thereof with:

• a) about 20 to about 70 percent by weight of organic waste material of the food industry, agriculture industry or both, said organic waste having a dry substance content of at least 20 percent by weight;
• and
• b) inoculating agents selected from the group consisting of a pectin cleaving enzyme, a thermophilic lactic acid bacteria culture having an activity of about 10.sup.6 to about 10.sup.10 cells per gram of dry substance, and a mixture thereof;
• and
• c) biological degradation agents selected from the group consisting of molasses, urea, organic carboxylic acids having 1 to 5 carbon atoms and mixtures thereof;
• and
• d) a starter culture having a high cellulase activity selected from the group consisting of Trichoderma viridae, Chaetonium globusum and Actinomycetes and mixtures thereof;
• wherein the resulting mixture is brought to a carbon/nitrogen ratio of about 1/20 to about 1/80 with waste material containing nitrogen, nitrogen-containing natural or synthetic fertilizer or a mixture thereof, and subsequently aerobically fermenting the mixture for about 2 to about 45 days.
