NOVELTY - Method of producing organic fertilizer from empty fruit bunch of oil palm, involves (a) first shredding the empty fruit bunch of oil palm into strips, (b) adding sludge or grass carbon soil into fruit bunch of oil palm, adding proper amount of cellulose fermentation bacterium and urea to the mixture, and spraying water (55-70%) to the mixture, (c) composting the mixture at high temperature for fermentation, and spraying water to each pile of materials during the fermentation process and stirring uniformly, and (d) preparing the mixture into organic series fertilizers.    USE - The method is useful for producing organic fertilizer.    DETAILED DESCRIPTION - Method of producing organic fertilizer from empty fruit bunch of oil palm, involves (a) first shredding the empty fruit bunch of oil palm into strips, (b) adding (in parts weight) sludge or grass carbon soil (0.1-1) into fruit bunch of oil palm (1), adding proper amount of cellulose fermentation bacterium and urea to ensure that ratio of carbon to nitrogen is 25:1-30:1 to the mixture, and spraying water (55-70%) to the mixture, (c) composting the mixture at high temperature for fermentation, and spraying water to each pile of materials during the fermentation process and stirring uniformly, and (d) preparing organic series fertilizers by finally preparing the materials which is completely fermented into at least one of three types of fertilizers chosen from (i) organic fertilizers which is prepared by adding into few amount or not adding inorganic materials which contains nitrogen and/or phosphorus and/or potassium and/or calcium and/or magnesium to the mixture and granulating the mixture, (ii) organic-inorganic compound fertilizers by adding into few amount or not adding inorganic materials which contains nitrogen and/or phosphorus and/or potassium and/or calcium and/or magnesium to the mixture to the mixture and granulating the mixture, and (iii) bioorganic fertilizers by adding proper amount of microorganism agent into the mixture and granulating the mixture.
