NOVELTY - Fertilizer comprises 15-25 wt.% bean cake, 12-28 wt.% rice bran, 18-25 wt.% distiller's grains, 25-40 wt.% manure, 2-5 wt.% expanded vermiculite powder, 0.5-0.8 wt.% rapeseed oil, 0.01-0.05 wt.% graphene, and straw (specific amount). USE - Used as fertilizer containing graphene. ADVANTAGE - The fertilizer: utilizes graphene for improving the dispersion effect; contains plant fiber raw materials; greatly reduces the loss of active ingredients in fertilizer; improves the use of fertilizer effect; its amount be reduced by more than 50%; and increases production to 15-20%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the fertilizer, comprising (a) placing the vermiculite into a crusher, crushing into powder, sieving through 250 meshes sieve, placing the sieved material in a wet ball mill, then adding water, graphene and rapeseed oil, and grinding by ball milling to obtain mixed material, (b) placing the bean cake into a stirrer, adjusting stirring speed to 150-200 rotations/minute (rpm), stirring for 10-15 minutes, then adjusting the stirring speed to 250-300 rpm, adding rice bran and straw, and stirring for 20-25 minutes, (c) adjusting the stirring speed to 380-400 rpm, then adding the manure, distiller's grains and mixture of step (a), and stirring for 25-30 minutes, and (d) drying, and granulating to obtain the fertilizer.
