DESCRIPTION
UNE EN 17721:2025
This document specifies a method for laboratory measurement of the pH value in liquid microbial plant biostimulants, using pH electrodes with a glass membrane. Plant biostimulants other than microbial plant biostimulants are excluded from the scope of this document because there is no essential requirement in the Regulation [1] for measuring the pH of non-microbial plant biostimulants.
