Plant biostimulants - Determination of phosphonates

active, Most Current
Organization: CEN
Publication Date: 1 March 2022
Status: active
Page Count: 16
ICS Code (Biology. Botany. Zoology): 07.080
scope:

This document specifies a method for the extraction and determination of phosphonates (P-PO3) in plant biostimulants using ion chromatography and conductivity detection (IC-CD).

This document is also applicable to the blends of fertilizing products where plant biostimulants are the main part of the blend. Otherwise, the Technical Specification for the main part of the blend applies.
