In one embodiment, a method includes providing agricultural grade gypsum to a mixing device using a conveyor, providing a fluid to the mixing device using a pump, mixing the agricultural grade gypsum with the fluid to produce a gypsum slurry using the mixing device, and pumping the gypsum slurry to a storage tank. In another embodiment a system includes a conveyor providing an agricultural grade gypsum, a pump providing a fluid, a mixing device configured to mix the agricultural grade gypsum provided by the conveyor with the fluid provided by the pump to produce a gypsum slurry, and a slurry pump configured to pump the gypsum slurry from the mixing device to a storage tank.

Syrup produced in a lignocellulosic biomass fermentation process is used as a binder for soil conditioning materials to make an agricultural composition that is easily handled and applied. The syrup binds powdery soil conditioning materials such as lime and gypsum to form pellets or granules.

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.

A method and system for the destruction of per- and polyfluoroalkyl substances (PFAS) in soil is disclosed. The method includes introducing a soil composition including PFAS into a sealed reactor vessel. An oxidant may be introduced into the reactor vessel, and the soil composition may be dosed with the oxidant to form a dosed soil composition, where the dosed soil composition is a soil slurry that includes between 20 wt % and 50 wt % solids. An alkaline additive may be introduced into the reactor vessel. The reactor vessel may then be pressurized to a pressure at or above 2,000 psi and heated to a temperature at or above 350 C. The dosed soil composition and alkaline additive may be maintained under the reactor pressure and reactor temperature for a reaction period sufficient to destruct more than 90 weight percent of the PFAS present in the dosed soil composition.
