Blue spirulina extract is made from the blue-green algae Spirulina platensis. It is rich in nutrients such as protein, vitamins, and minerals.
In plant growth, blue spirulina extract has been found to have a positive effect on the growth and development of plants. Studies have shown that when added to the soil or used as a foliar spray, blue spirulina extract can improve plant growth, increase the number of leaves and branches, and enhance the overall health of the plant.
For example, a study published in the Journal of Applied Phycology in 2014 found that when blue spirulina extract was applied to tomato plants, it led to a significant increase in the number of leaves, branches, and fruits. The plants also had a higher chlorophyll content, indicating improved photosynthesis.
Another study published in the Journal of Plant Interactions in 2016 found that when blue spirulina extract was applied to wheat plants, it led to a significant increase in the plant's growth, biomass, and protein content.
