NOVELTY - Fertilizer comprises 21-23 pts. wt. decomposed duck manure, 11-13 pts. wt. plant ash, 17-19 pts. wt. nitrogen fertilizer, 13-15 pts. wt. potassium fertilizer, 14-16 pts. wt. phosphate fertilizer, 12-15 pts. wt. sea-manure, 9-11 pts. wt. potassium sulfate, 7-9 pts. wt. fern green manure, 8-10 pts. wt. manganese chloride, 5-7 pts. wt. alginic acid, 3-5 pts. wt. boron fertilizer, 2-4 pts. wt. fungi fertilizer, 3-6 pts. wt. strong stems spirit, 4-6 pts. wt. selenium humate, 1-3 pts. wt. manganese-zinc ferrite nanoparticles and 60-70 pts. wt. water.    USE - The fertilizer is useful for celery (claimed), and promoting celery stem stout thickness, and growth of plants.    ADVANTAGE - The fertilizer is rich in nutrients; produces plants with fresh green leaves, and natural flavored thickness; improves the resistance to pests, and diseases in celery; and increases the production, and quality of celery.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the fertilizer, comprising either uniformly stirring all the above mentioned raw materials with specified proportions with mixing, and fermenting with sealing for 3.5 hours, to obtain the product; or uniformly stirring 21 pts. wt. decomposed duck manure, 11 pts. wt. plant ash, 17 pts. wt. nitrogen fertilizer, 13 pts. wt. potassium fertilizer, 14 pts. wt. phosphate fertilizer, 12 pts. wt. sea-manure, 9 pts. wt. potassium sulfate, 7 pts. wt. fern green manure, 8 pts. wt. manganese chloride, 5 pts. wt. alginic acid, 3 pts. wt. boron fertilizer, 2 pts. wt. fungi fertilizer, 3 pts. wt. strong stems spirit, 4 pts. wt. selenium humate, 1 pts. wt. manganese-zinc ferrite nanoparticles and 60 pts. wt. water, with mixing, and fermenting with sealing for 3.5 hours, to obtain the product; or uniformly stirring 22 pts. wt. decomposed duck manure, 12 pts. wt. plant ash, 18 pts. wt. nitrogen fertilizer, 14 pts. wt. potassium fertilizer, 15 pts. wt. phosphate fertilizer, 14 pts. wt. sea-manure, 10 pts. wt. potassium sulfate, 8 pts. wt. fern green manure, 9 pts. wt. manganese chloride, 6 pts. wt. alginic acid, 4 pts. wt. boron fertilizer, 3 pts. wt. fungi fertilizer, 5 pts. wt. strong stems spirit, 5 pts. wt. selenium humate, 2 pts. wt. manganese-zinc ferrite nanoparticles and 65 pts. wt. water, with mixing, and fermenting with sealing for 3.5 hours, to obtain the product; or uniformly stirring 23 pts. wt. decomposed duck manure, 13 pts. wt. plant ash, 19 pts. wt. nitrogen fertilizer, 15 pts. wt. potassium fertilizer, 16 pts. wt. phosphate fertilizer, 15 pts. wt. sea-manure, 11 pts. wt. potassium sulfate, 9 pts. wt. fern green manure, 10 pts. wt. manganese chloride, 7 pts. wt. alginic acid, 5 pts. wt. boron fertilizer, 4 pts. wt. fungi fertilizer, 6 pts. wt. strong stems spirit, 6 pts. wt. selenium humate, 3 pts. wt. manganese-zinc ferrite nanoparticles and 70 pts. wt. water, with mixing, and fermenting with sealing for 3.5 hours, to obtain the product.
