NOVELTY - A Dendrobium organic fertilizer comprises cow dung, magnesium sulfate, soluble phosphorus anhydride, water-soluble potassium oxide, amino acid chelated manganese, amino acid chelated manganese, amino acid chelated copper, amino acid chelated boron, amino acid chelated molybdenum, composite microbial agents, diammonium phosphate, ammonium nitrate, potassium salts, river silt, peanut cake, red jade soil, peat, zeolite powder, sodium bicarbonate, and water.    USE - Dendrobium organic fertilizer.    ADVANTAGE - The organic fertilizer prevents soil compaction, and increases soil moisture retention.    DETAILED DESCRIPTION - A Dendrobium organic fertilizer comprises 50-60 pts. wt. cow dung, 4-5 pts. wt. magnesium sulfate, 0.4-0.6 pts. wt. soluble phosphorus anhydride, 0.2-0.3 pts. wt. water-soluble potassium oxide, 4-5 pts. wt. amino acid chelated manganese, 4-5 pts. wt. amino acid chelated manganese, 4-5 pts. wt. amino acid chelated copper, 4-5 pts. wt. amino acid chelated boron, 2-3 pts. wt. amino acid chelated molybdenum, 3-4 pts. wt. composite microbial agents, 6-8 pts. wt. diammonium phosphate, 8-10 pts. wt. ammonium nitrate, 3-4 pts. wt. potassium salts, 20-30 pts. wt. river silt, 25-45 pts. wt. peanut cake, 10-16 pts. wt. red jade soil, 8-12 pts. wt. peat, 2-3 pts. wt. zeolite powder, 2-3 pts. wt. sodium bicarbonate, and balance water. The composite microbial agents include photosynthetic bacteria, lactic acid bacteria group, and actinomycetes flora. An INDEPENDENT CLAIM is included for the preparation of organic fertilizer comprising:    (A) drying the cow dung and deodorizing, mixing with the peanut bran, soybean bran, peat moss, river sludge, and red corundum in the compost pool code stack, adding composite microorganism microbial inoculum and water, and fermenting under normal temperature aerobic condition for 30-40 days to obtain compost fermentation material;    (B) mixing magnesium sulfate, amino acid chelated iron, amino acid chelated manganese, amino acid chelated copper, amino acid chelated boron, amino acid chelated molybdenum, diammonium phosphate, ammonium nitrate, potassium salt discharging mixing cycles, and fully grinding mixture into fine powder, sieving by 60-80 meshes sieve to obtain the fine powder and mixing the powder with the fermentation material and granulating;    (C) mixing water-soluble phosphoric acid anhydride and potassium oxide solution at a mass ratio of 1:4, dissolving in water, and stirring into uniform aqueous solution;    (D) uniformly spraying the zeolite powder on the surface of the wet granules obtained from step (C) to form a coated layer;    (E) heating the melted paraffin and forming a coated second layer; and    (F) mixing the resulting particles with the remaining materials, drying at low-temperature and cooling, and packing into bag to obtain the product.
