## Abstract

The present disclosure relates to a nutrient-containing porous biodegradable bead comprising the following components: an Aloe Vera and cellulose composite matrix containing a nutrient solution including, but not limited to, nitrogen, phosphorus, potassium, sodium alginate, and calcium chloride.

## Claims

### Claim 1

A biopolymer-based capsule, comprising: a capsule, wherein said capsule comprises a shell that encapsulates a plurality of substances;
wherein said shell is a biopolymer-based matrix comprising a combination of sodium alginate and calcium chloride;
wherein sodium alginate is at least 1%-5% by weight of the capsule and wherein calcium chloride is at least 1%-5% by weight of the capsule; and
wherein said shell comprises a plurality of biopolymer base matrices, wherein a first biopolymer base matrix includes a combination of Aloe Vera and cellulose and a second biopolymer base matrix includes a combination of sodium alginate and calcium chloride, wherein Aloe Vera is at least 5.5% by weight of the capsule, wherein cellulose is at least 5.5% by weight of the capsule.

### Claim 2 (depends on 1)

The biopolymer-based capsule of claim 1, wherein a first substance of said plurality of substances is water and a second substance of said plurality of substances is a fertilizing material comprising an effective combination of Nitrogen, Phosphorus, and Potassium.

### Claim 3 (depends on 2)

The biopolymer-based capsule of claim 2, wherein Nitrogen is at least 0.033% by weight of the capsule, Phosphorus is at least 0.033% by weight of the capsule, and Potassium is at least 0.033% by weight of said capsule.

### Claim 4 (depends on 1)

The biopolymer-based capsule of claim 1, wherein said first biopolymer base matrix surrounds said second biopolymer base matrix and said first biopolymer base matrix is the outermost layer of said shell.

### Claim 5 (depends on 4)

The biopolymer-based capsule of claim 4, wherein a first substance of said plurality of substances is water and second substance of said plurality of substances is a fertilizing material comprising a combination of Nitrogen, Phosphorus, and Potassium.

### Claim 6 (depends on 5)

The biopolymer-based capsule of claim 5, wherein Nitrogen is at least 0.033% by weight, Phosphorus is at least 0.033% by weight, and Potassium is at least 0.033% by weight of said capsule.

### Claim 7 (depends on 3, 6)

The biopolymer-based capsule of claim 3 or 6, wherein the diameter of said capsule is between 4 millimeters and 15 millimeters.
