## Abstract

The invention relates to a particularly basic inorganic soil conditioner containing an inorganic carbonate as the base thereof, characterised in that it comprises at least one “dynamic disintegration” agent capable of causing a breakdown, considerable fragmentation, dispersion, and considerable “dispersion” within the granule, i.e. a force inside and/or on the surface of the granule that tends to cause the granule to break down or “explode” when said granule contacts the soil, and specifically contacts the water or moisture of the soil, and in that said carbonate is preferably natural or precipitated calcium carbonate.

## Claims

### Claim 1

A compacted granule for agriculture application consisting of a mineral enriching agent, 0.5 to 7% by dry weight mass of a disintegration agent, molasses, and optionally a fertilizer, wherein the mineral enriching agent comprises calcium carbonate, and the disintegration agent is a swelling bentonite, wherein the compacted granule has a diameter of 2 to 5 mm and a substantially polygon shape, wherein the compacted granule is prepared by dry blending the mineral enriching agent, the disintegration agent, the molasses, and optionally the fertilizer, to obtain a blended mixture, subjecting the blended mixture to roller compaction to obtain a compacted blended mixture in the form of a plate, breaking up the plate to form compacted granules, and screening the compacted granules to obtain a compacted granule having a diameter of 2 to 5 mm and a substantially polygon shape, and wherein the compacted granule bursts or explodes from an internal force within the granule upon exposure to water or moisture to obtain a ground coverage of 2 to 5 cm of the mineral enriching agent.

### Claim 2 (depends on 1)

The compacted granule according to claim 1, wherein the mineral enriching agent is natural calcium carbonate.

### Claim 3 (depends on 1)

The compacted granule according to claim 1, wherein the mineral enriching agent is precipitated calcium carbonate.

### Claim 4 (depends on 1)

The compacted granule according to claim 1, wherein the mineral enriching agent comprises calcium carbonate and dolomite.

### Claim 5 (depends on 1)

The compacted granule according to claim 1, wherein the bentonite has a maximum water content 14%, a 30% maximum overtail of 30%, a 75-micron sieve under dry testing, and a specific weight of 2.3 g/cm3.

### Claim 6 (depends on 1)

The compacted granule according to claim 1, including 1 to 7% by dry weight mass of bentonite.

### Claim 7 (depends on 1)

The compacted granule according to claim 1, including 1 to 5% by dry weight mass of bentonite.

### Claim 8 (depends on 1)

The compacted granule according to claim 1, including 1 to 3% by dry weight mass of bentonite.

### Claim 9 (depends on 1)

The compacted granule according to claim 1, including 2% by dry weight mass of bentonite.

### Claim 10 (depends on 1)

The compacted granule according to claim 1, including 0.6 to 6% by dry weight mass of the disintegration agent.

### Claim 11 (depends on 1)

The compacted granule according to claim 1, further comprising a fertilizer.

### Claim 12 (depends on 11)

The compacted granule according to claim 11, wherein the fertilizer is a natural phosphate, an ammonia nitrogenous fertilizer, or a blend thereof.

### Claim 13 (depends on 1)

A fertilizer comprising the compacted granule according to claim 1.
