Soil Stabilization Approach via Crude Plant Extracts

The enzyme-induced calcium carbonate precipitation is a new and eco-friendly method to improve the soil. This study pursues an approach to make the urease enzyme less expensive. To this end, six different types of plants were grown, and then the urease enzyme activity in their crude extracts was measured. The highest activity of the urease enzyme was obtained for the soybean plant. Then, the amount of calcium carbonate sediments obtained when using these extracts has been optimized. X-ray diffraction and scanning electron microscopy analyses was carried out to identify the type of material that is formed after the precipitation process. Calcium carbonate was observed in all the sediments. The best condition to get the most sediment was used to treat only sandy soil and sandy soil mixed with silt. Several plant extracts were tested to see if they could make soil more resistant based on the unconfined compressive strength test. The strongest soil was found when using soybean plant extract along with sand only. The findings suggest that using plant extracts instead of pure enzymes in the enzyme-induced calcium carbonate precipitation method can be effective.
