mineral fertilizer, fertilizer manufacturing process in dynamically disintegrating granules, and fertilizer application

摘要

Mineral soil conditioner containing a mineral carbonate as a base comprises at least one agent for dynamic disintegration that can cause a burst, high fragmentation, dispersion, strong dispersion in the granule, that is, involving a force to inside and/or on the surface of the granule for bursting or exploding the granule, when the granule is contacting with water and/or humidity including soil and more specifically water or soil humidity. An independent claim is included for a process for the fabrication of granules having dynamic disintegration agent comprising carrying out a conventional granulation by adding and incorporating molasse, dry mixing of the conditioner and disintegration agent, which comprises: a medium swelling product, which is a swelling clay, preferably bentonite, in an amount of 0.5-0.7 to 6-7 wt.%, preferably 2 wt.%, based on dry weight, of the material to be granulated, high speed stirring, then passing between two rolling compactor to form a continuous plate, kind of carpet of 2-3 mm-thick, breaking to form polygonal granules which are eroded and passed in screening before to form the final granulate, in the form of polygons more or less regular. ACTIVITY : Fertilizer. MECHANISM OF ACTION : None given.
