Standards Development
This standard specifies the requirements and test methods for Plant Growth Promoting Rhizobacteria (PGPR) in Biofertilizers, focusing on their Plant growth hormones producing ability. It applies to both solid and liquid Biofertilizers containing PGPR intended for use in overseeding or soil, root and seedling inoculation across various plant species.
Developing an ISO standard for biofertilizers (Bio stimulant) and Plant Growth-Promoting Rhizobacteria (PGPR) is important because the sector currently faces major problems with product quality, consistency, safety, efficacy, and international trade. ISO Standard is Important to ensure product quality, establish minimum requirements for viable microbial counts (CFU), define acceptable levels of contamination and standardize carrier materials, formulation, moisture, pH, and shelf life.
