NOVELTY - Soil modifier comprises 44-48 pts. wt. biomass fertilizer, 22-24 pts. wt. humic acid, 12-16 pts. wt. fly ash, 10-14 pts. wt. attapulgite, 8-14 pts. wt. complex microorganism, 6-10 pts. wt. bentonite, 7-9 pts. wt. modified graphene, 6-8 pts. wt. chitosan, and 3-5 pts. wt. activated carbon. USE - Used as soil modifier. ADVANTAGE - The soil modifier has no pollution, is environmentally friendly, has short period of treatment, has quick effect and high use value and good application prospect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation of soil modifier comprising (i) providing raw materials, (ii) adding the pre-treated animal manure, straw powder, seaweed residue, plant ash, lees, and sludge to the high-speed disintegrator to crush to obtain mixture A, mixing mixture A, humic acid, fly ash and then introducing to the high-speed stirrer to stir at a stirring speed of 1100-1200 revolutions/minute for 35-45 minutes, obtaining mixture B, (iii) adding the complex microorganism into the fermenting tank, adding water (required amount), fermenting, increasing fermentation product inner part temperature to more than 60 degrees C, first time stirring once every 14-18 hours, when internal temperature of the fermentation is maintained at 45-55 degrees C, finishing fermentation to obtain mixture C, and (iv) adding mixture B and mixture C, attapulgite, modified bentonite, modified graphene, chitosan, and activated carbon into the high-speed mixer, fully stirring to make all materials mix evenly, where the rotating speed is 900-1000 revolutions/minute, the stirring time is 1-2 hours, and then placing the mixture into a drying machine, drying at 50-60 degrees C, introducing to a granulator to granulate to obtain the soil modifier.
