PURPOSE: An earth composition of high performance is provided to improve the intensity and durability of soil through a biochemical reaction of soil and microorganism, and to facilitate crack control, purification and heavy metal absorption of the soil. CONSTITUTION: An earth composition of high performance using microorganism includes 70~85 wt% of soil, 0.01~10 wt% of microorganism, and 5~29.99 wt% of lime or alkaline chemicals for pH control for a microorganism activity. The alkaline chemicals are one selected from the group consisting of NaOH, CaCl2, KOH, sodium silicate, and potassium silicate. The microorganism is one selected from the group consisting of Sporosarcina pasteurii, Pseudomonas aeruginosa, Bacillus sphaericus, Bacillus Subtilis, Shewanella algae BrY, Mvxococcus Xanthus, and Mycobacterium smeamatis.
