Soil amendment for regulating salinity and alkalinity and solidifying heavy metals, preparation and application thereof

Abstract

A soil amendment for regulating salinity and solidifying heavy metals includes 50-70 parts by weight of natural calcium-based bentonite, 20-25 parts by weight of fly ash, 10-20 parts by weight of water, 20-25 parts by weight of weathered coal, and 2-6 parts by weight of composite microbial agent. The soil amendment not only efficiently removes pollutants from poor-quality soil, but also increases the yield and quality of plants. It can also provide a new idea for expanding the application research of the natural calcium-based bentonite, the fly ash, the weathered coal, and salt and drought-resistant plants to more fields. This degradation of the soil amendment has high efficiency, low cost, easy operation, and does not cause secondary pollution, and has broad application prospects.
