## Abstract

A method of manufacturing a fertilizer, including grinding solid vermicompost to create solid ground vermicompost powder, creating a liquid suspension agent, adding the solid ground vermicompost powder to the liquid suspension agent to create a liquified vermicompost solution, filtering the liquified vermicompost solution to create a concentrated liquified vermicompost mixture, and adding dispersant to the concentrated liquified vermicompost mixture.

## Claims

### Claim 1

A method of manufacturing a fertilizer, comprising:
grinding solid vermicompost to create solid ground vermicompost powder;
creating a liquid suspension agent;
adding the solid ground vermicompost powder to the liquid suspension agent to create a liquified vermicompost solution;
filtering the liquified vermicompost solution to create a concentrated liquified vermicompost mixture; and,
adding dispersant to the concentrated liquified vermicompost mixture.

### Claim 2 (depends on 1)

The method as recited in claim 1, wherein the step of creating a liquid suspension agent comprises:
mixing a thickening agent with water.

### Claim 3 (depends on 2)

The method as recited in claim 2, wherein the thickening agent is selected from the group consisting of cellulosic thickener, cellulose gum, cellulose ethers, and xanthan gum.

### Claim 4 (depends on 2)

The method as recited in claim 2, wherein the thickening agent is xanthan gum.

### Claim 5 (depends on 1)

The method as recited in claim 1, wherein the step of adding the solid vermicompost powder to the liquid suspension agent to create a liquified vermicompost solution comprises:
adding the solid vermicompost powder to the liquified vermicompost solution under high speed mixing.

### Claim 6 (depends on 1)

The method as recited in claim 1, further comprising:
adding a surfactant to the liquified vermicompost solution.

### Claim 7 (depends on 1)

The method as recited in claim 1, wherein the step of filtering the liquified vermicompost solution to create a concentrated liquified vermicompost mixture comprises:
separating purified vermicompost of the liquid vermicompost solution from waste vermicompost of the liquid vermicompost solution via gravity; and,
separating the purified vermicompost from the waste vermicompost via decanting.

### Claim 8 (depends on 7)

The method as recited in claim 7, further comprising:
collecting and cleaning the waste vermicompost to be further processed for additional vermicompost.

### Claim 9 (depends on 1)

The method as recited in claim 1, wherein the dispersant comprises one or more surfactants.

### Claim 10

A method of manufacturing a fertilizer, comprising:
creating a liquid suspension agent;
creating a dispersing agent solution;
mixing the liquid suspension agent and the dispersing agent solution to create a premix solution; and,
adding solid vermicompost to the premix solution while grinding to create a liquified vermicompost mixture.

### Claim 11 (depends on 1)

The method as recited in claim 1, wherein the step of mixing the liquid suspension agent and the dispersing agent solution to create a premix solution comprises:
mixing the liquid suspension agent and the dispersing agent solution while grinding to create the premix solution.

### Claim 12 (depends on 1)

The method as recited in claim 1, wherein the step of creating a liquid suspension agent comprises:
mixing a thickening agent with water.

### Claim 13 (depends on 10)

The method as recited in claim 10, wherein the step of creating a dispersing agent solution comprises:
mixing a dispersing agent with water.

### Claim 14 (depends on 10)

The method as recited in claim 10, wherein the step of adding solid vermicompost to the premix solution while grinding to create a concentrated liquified vermicompost mixture comprises:
grinding the solid vermicompost to create ground solid vermicompost; and,
adding the ground solid vermicompost to the premix solution while grinding to create the concentrated liquified vermicompost mixture.

### Claim 15 (depends on 10)

The method as recited in claim 10, further comprising the step of:
grinding the liquified vermicompost mixture.

### Claim 16 (depends on 10)

The method as recited in claim 10, further comprising the step of:
adding water to the liquified vermicompost mixture.

### Claim 17 (depends on 10)

The method as recited in claim 10, further comprising the step of:
filtering and/or decanting the vermicompost mixture to create a concentrated liquified vermicompost mixture.

### Claim 18

A liquified vermicompost mixture to be used as a fertilizer, comprising:
a thickening agent;
a dispersing agent;
vermicompost; and,
water.

### Claim 19 (depends on 18)

The liquified vermicompost mixture as recited in claim 18, wherein the vermicompost comprises ground worm castings.

### Claim 20 (depends on 17)

The liquified vermicompost mixture as recited in claim 17, wherein the dispersing agent comprises one or more surfactants.
