    • The invention relates to a fertilizer granule comprising both a nitrate and urea as the main nitrogen source. A mineral added during production is an important component in the composition, said mineral stabilizing these otherwise poorly compatible nitrogen compounds. A high nitrogen content is thus attained with ammonium nitrate concentrations falling below maximum limit values set by international legislation and classification, while at the same time the explosion risk particularly associated with the use of ammonium nitrate is avoided. The invention is also directed to a process for the production of the fertilizer granule of the above type, said process resulting in a fertilizer granule with excellent resistance properties and a high nitrogen content, wherein said granule may be coated by methods typical in the art, if desired.
