TS EN 17836

TS EN 17836 is a standard that addresses how the physical unit forms of fertilizers are described and distinguished. It brings together the terminology used for the physical appearance of solid organic, organo-mineral and inorganic macronutrient fertilizers so that product descriptions, labeling and technical communication use the same terms consistently.

Why physical form matters

In fertilizer practice, the physical unit form is a key descriptor of how a product is presented: for example as a granular material, prills, powder-like product, or another solid form. This distinction matters not only for appearance, but also for handling, flowability, blending behavior, storage performance and application method. In general technical context, two fertilizers with the same nutrient content may be supplied in different physical forms, so standardized terminology helps reduce confusion, product misidentification and misuse.

Technical field covered by this standard

• Solid organic fertilizers
• Solid organo-mineral fertilizers
• Solid inorganic macronutrient fertilizers
• Description and naming of their physical unit forms

This document is best understood as a conceptual terminology standard rather than a test method for measuring chemical performance or nutrient content. Its value lies in providing a common technical language for the physical form of fertilizer products. It is used to describe product form accurately and consistently, not to establish chemical composition limits, production routes or performance guarantees.
