Abstract

Official abstract text for this publication.

The present invention provides for biochar coated particles and a method for coating the particles with biochar.

First claim

Opening claim text (preview).

We claim: 1. A method for coating a plant seed with biochar, the method comprising the steps of (i) creating a slurry comprised of biochar and a binder wherein the biochar, prior to creating the slurry, is treated by the infusion of one or more liquids into pores of the biochar at least in part by a surfactant infusion treatment, (ii) contacting the seed with the slurry to coat the seed, wherein coating the seed with the slurry improves seed germination, increases seed survivability, increases plant growth and sustains plant life, and (iii) drying the coated seed. 2. The method of claim 1 wherein the binder is one or more substances selected from the group: a starch, sugar, gum arabic, cellulose, clay, and polymer. 3. The method of claim 1 wherein the step of contacting the seed with the slurry is repeated until the coat substantially surrounding the seed is between 0.01 and 100 times the diameter of the seed. 4. The method of claim 1 wherein the slurry further includes a fertilizer. 5. The method of claim 1 wherein the infusion of one or more liquids into pores of the biochar is accomplished at least in part by a vacuum processing treatment. 6. The method of claim 1 wherein the seed is one of the following seed types: grass, corn, wheat, barley, soybeans, rice, sugar beet, ornamental plant, citrus, or vegetable. 7. A method for coating a plant seed with biochar, the method comprising the steps of (i) treating the biochar by the infusion of one or more liquids into pores of the biochar at least in part by a surfactant infusion treatment and (ii) contacting the seed with the treated biochar to coat the seed, wherein coating the seed with the treated biochar improves seed germination, increases seed survivability, increases plant growth and sustains plant life. 8. A method for coating a plant seed with biochar, the method comprising the steps of (i) treating the biochar by the infusion of one or more liquids into pores of the biochar at least in part by a surfactant infusion treatment and (ii) contacting the seed with the treated biochar to coat the seed, wherein the treated biochar is only one of several elements used to coat the seed and wherein coating the seed with the biochar improves seed germination, increases seed survivability, increases plant growth and sustains plant life. 9. A method for coating a plant seed with biochar, the method comprising the steps of (i) treating the biochar by the infusion of one or more liquids into pores of the biochar at least in part by a surfactant infusion treatment, (ii) mixing the treated biochar with other materials used for seed coating and (iii) contacting the treated biochar mixture with the seed, wherein coating the seed with the slurry improves seed germination, increases seed survivability, increases plant growth and sustains plant life.
