摘要
The invention relates to a process for the production of thermally stable and strong fertilizer granules which contain a potassium- and/or magnesium-containing mica, such as phlogopite and/or biotite, as well as potassium and/or magnesium derived partly in a water-soluble form from these minerals by nitric acid etching. The granules may additionally contain conventional plant nutrients. The invention also relates to products produced by the above process.
