Estimating the term…
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.
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.
