## Abstract

A soil amendment is provided and a method for making the same, where the soil amendment is encasing biochar in a biodegradable material. The biochar encased in the biodegradable material may be either or both treated and untreated (raw) biochar. The biodegradable material encasing the biochar may be sealed to produce a packet or capsule, or deposited on a sheet of biodegradable material. The sheet of biodegradable material may include a biodegradable adhesive, creating a biochar tape on the biodegradable material. In another example the biodegradable material may be immersed in a solution containing biochar to create a soil amendment, for example, to wrap a root ball of a seedling or sapling. The biodegradable material may, for example, be a polymer, wax, oil, or paraffin which is used to create a bead, capsule, or pod of biochar or biochar slurry, or may be a fiber based or polymer based material that can be formed into a shape, such as a liner, container, or a disc.

## Claims

### Claim 1

A soil amendment comprised of biochar encased within a biodegradable material, wherein the biodegradable material is surrounding the root ball of a seedling or sapling that has been immersed in a solution of biochar and liquid.

### Claim 2

A soil amendment comprised of biochar encased within a biodegradable material, wherein the biodegradable material is surrounding the root ball of a seedling or sapling that is saturated with moisture, adhesive, a binder, or a combination thereof, and then contacted with biochar or treated biochar.

### Claim 3

A soil amendment comprised of biochar encased within a biodegradable material, wherein the biodegradable material is a moldable material and thus the resulting biochar encasement is a liner, disc, or container, and wherein the biodegradable material is a pulp mixture that includes peat moss, coconut fiber, coco fiber, wood fiber, cardboard fiber, paper fiber, rice hulls, bamboo, or composted manure.

### Claim 4

A soil amendment comprised of biochar encased within a biodegradable material, wherein the biochar is in a slurry form.
