Agrisea’s proprietary fermentation technology was utilized in the fermentation of Sugar Kelp (sourced from North American seaweed farmers). To assess the effectiveness of the fermented product, a plant growth bioassay was conducted, specifically focusing on mung bean root growth as an indicator.

During the bioassay, different concentrations of the fermented products were tested ranging from 0.1g/L to 5.0 g/L. Results from the assay indicated that 1.0 g/mL treatment concentration was the optimal range for adventitious root growth. In addition to the Sugar Kelp fermented products, a commercial control was also included, along with water (negative control) and Bull Kelp fermented product (comparison to another seaweed biostimulant).

Some of the parameters tested were root count, root length, root fresh weight, root dry weight, root volume, root surface area and root diameter. The Sugar Kelp fermented product outperformed the Bull Kelp product against all the tested parameters and was comparable to the commercial control in the tested parameters, suggesting its ecacy as a plant growth promoter.
