A soil-stabilizing composition comprising:
- (i) a solution A comprising Azotobacter vinelandii, Acidithiobacillus ferrooxidans and a Pseudomonas aeruginosa alginase;
- wherein solution A comprises from 8% to 15% Azotobacter vinelandii as a percentage by weight based on the total weight of solution A, from 11% to 19% Acidithiobacillus ferrooxidans as a percentage by volume based on the total volume of solution A, and from greater than 0% to 5% of alginase as a percentage by weight based on the total weight of solution A;
- and
- (ii) a solution B comprising cations in the form of calcium chloride;
- wherein solution B contains from 20% to 35% calcium chloride as a percentage by weight based on the total weight of solution B.
