## Abstract

This invention relates to a process for producing an organic fertilizer, and an organic fertilizer containing organic carbon carriers. According to an embodiment of the invention, the organic fertilizer is produced by mixing organic matter with water adding an organic acid or acids such as EDTA, amino acids, fuivic acid or propionic acid, preferably propionic acid (25%); or a base such as KOH or NaOH1 preferably KOH to the mixture; and decomposing organic matter with the acid/s or base in order to extract organic carbon solution having a carbon content of 10 to 20. The invention also relates to an organic fertilizer containing macro or micro nutrientfe and an organic carrier bound to or complexed with an organic carbon carrier.

## Claims

### Claim 1

A process for producing an organic fertilizer containing organic carbon carriers, the process comprising the following steps:
1) mixing organic matter with water adding an organic acid; or a base to the mixture; and
2) decomposing organic matter with the acid/s or base in order to extract organic carbon solution having a carbon content of 10 to 20%.

### Claim 2 (depends on 1)

The process according to claim 1, wherein the organic acid is EDTA, amino acids, fulvic acid or propionic acid.

### Claim 3 (depends on 2)

The process according to claim 2, wherein the organic acid is propionic acid (25%).

### Claim 4 (depends on 1)

The process according to claim 1, wherein the base is KOH or NaOH.

### Claim 5 (depends on 4)

The process according to claim 4, wherein the base is KOH.

### Claim 6 (depends on 1)

The process according to claim 1, wherein the carbon content is about 16%.

### Claim 7 (depends on 1)

The process according to claim 1, wherein the organic matter is peat, coal, or animal waste.

### Claim 8 (depends on 7)

The process according to claim 7, wherein the organic matter is peat.

### Claim 9 (depends on 1)

The process according to claim 1, wherein 600-1300 litres of water is added per 100 kg of dry organic matter.

### Claim 10 (depends on 1)

The process according to claim 1, wherein from 5 to 25 litres of organic acid is added per 100 kg dry organic matter.

### Claim 11 (depends on 1)

The process according to claim 1 wherein from 6 to 14 kg base is added per 100 kg dry organic matter.

### Claim 12 (depends on 1)

The process according to claim 1, wherein a nutrient or nutrients are added.

### Claim 13 (depends on 12)

The process according to claim 12, wherein the nutrients are a Potassium, Calcium, Magnesium or Ammonium salt, urea and/or micro nutrient/s.

### Claim 14

An organic fertilizer containing macro or micro nutrient/s bound to or complexed with an organic carbon earner.

### Claim 15

A liquid composition containing calcium, propionic acid and carbon carriers.

### Claim 16

A calcium propionate organic fertilizer.

### Claim 17

A process for producing a dry organic fertilizer wherein dry organic matter is mixed with an organic acid or acids, at an amount of between 5 and 25 litres per 100 kg organic matter; and water is then added until the moisture content of the organic matter reaches approximately 20%, and thereafter a dry nutrient is added.

### Claim 18 (depends on 17)

The process according to claim 17, wherein the dry organic matter is peat.

### Claim 19 (depends on 17)

The process according to claim 17, wherein the organic add is EDTA, amino acids, fulvic acid or propionic acid.

### Claim 20 (depends on 19)

The process according to claim 19, wherein the organic acid is propionic acid (25%).

### Claim 21 (depends on 17)

The process according to claim 17, wherein the dry nutrient is potassium sulphate or potassium chloride or a combination of the potassium salts.
