Basic Information
Scope
Scope: The content of the document constitutes the essential provisions of this document through normative references in the text. Among them, the referenced documents with dates only apply to the version corresponding to that date; for the referenced documents without dates, the latest version (including all amendment sheets) applies to this document. Main technical content: The group standard for "Non-Water-Soluble Magnesium-Silicon-Calcium Fertilizer" applies to granular fertilizers containing silicon, calcium, magnesium, and trace elements, which are mainly made from high-temperature-treated phosphate flotation tailings and/or yellow phosphorus slag as raw materials through processes such as crushing, mixing, and granulation. It can be used as a standalone fertilizer or mixed into fertilizers to supplement the plant's required medium and trace elements. Its main technical indicators include effective calcium (Ca), effective magnesium (Mg), soluble silicon (SiO2), and the content of trace elements (Cu+Fe+Mn+Zn+B). It also sets requirements for moisture, particle size, and pH indicators.
