Abstract
The present disclosure describes a method of treating soil and a method of sequestering heavy metals in soil. The method of treating soil includes applying a blend to the soil to form treated soil, the blend including a slag by-product having a soluble compound. The soluble compound includes silicon. The method of sequestering heavy metals includes applying a blend to soil to form treated soil, the blend including a slag by-product having a soluble compound, and forming a substantially inert particle in the treated soil, the substantially inert particle including the blend and the heavy metals.
Claims18
A method of treating soil, the method comprising:
- applying a blend to the soil to form treated soil, the blend including a slag by-product having a soluble compound, the soluble compound including silicon;
- and
- determining a concentration of silicon from the soluble compound in the treated soil;
- wherein the applying of the blend to the soil is during a period selected from the group consisting of a post-dormancy period, a dormancy period, a post-harvest period, and combinations thereof.
A method of treating soil, the method comprising:
- applying a blend to the soil and contacting a seed in the soil with the blend to form the treated soil, the blend including a sulfate source and a slag by-product having a soluble compound, the slag by-product being a carbon steel slag by-product, an alloy steel slag by-product, a stainless steel slag by-product, a non-ferrous slag by-product, or a combination thereof;
- and
- determining a concentration of silicon from the soluble compound in the treated soil;
- wherein the slag by-product has been produced from slag by a separation process;
- wherein the treated soil has a greater concentration of the silicon from the soluble compound than the soil;
- and
- wherein the concentration of the silicon from the soluble compound in the treated soil is at least 15 parts per million.
A method of sequestering heavy metals in soil, the method comprising:
- applying a blend to the soil to form treated soil, the blend including a sulfate source and a slag by-product having a soluble compound, the slag by-product being a carbon steel slag by-product, an alloy steel slag by-product, a stainless steel slag by-product, a non-ferrous slag by-product, or a combination thereof;
- and
- forming a substantially inert particle in the treated soil, the substantially inert particle including the blend and one or more of the heavy metals;
- and
- determining a concentration of silicon from the soluble compound in the treated soil;
- wherein the slag by-product has been produced from slag by a separation process;
- and
- wherein the treated soil has a concentration of silicon from the soluble compound that is at least 15 parts per million.
