NOVELTY - Preparation of modified graphene-based organic fertilizer comprises mixing 32-38 pts. wt. humus soil, 6-10 pts. wt. potassium fulvate, 8-14 pts. wt. straw powder and 14-18 pts. wt. waste fungus residue, mixing, adding into deionized water, ultrasonically dispersing for 18-22 minutes, adding 22-26 pts. wt. modified graphene, reacting at 75-85 degrees C for 25-35 minutes, adding 6-10 pts. wt. gluconic acid, adjusting pH to 6.0, adding 12-16 pts. wt. biomass plant ash, 3-6 pts. wt. nanosol and 1-3 pts. wt. nitrocellulose to obtain premix, adding premix and 6-10 pts. wt. modified volcanic glass into high-speed mixer, mixing and stirring at stirring speed of 355-365 revolutions/minute (rpm) for 45 minutes and granulating in granulator. USE - Method for preparing modified graphene-based organic fertilizer used for repairing soil (claimed). ADVANTAGE - The fertilizer can provide rich nutrients.
