Alginate oligosaccharide (AOS) is natural biostimulants, it is seaweed extract . It derived from brown seaweed, which is rich in polysaccharides such as alginic acid. When alginic acid is hydrolyzed, it yields AOS, which has a lower molecular weight and higher solubility than alginic acid. This makes AOS an ideal biostimulant for crops as it can be easily absorbed by plants and has a variety of beneficial effects. AOS is known to stimulate plant growth by increasing root development, improving nutrient uptake, and enhancing photosynthesis. AOS also promotes the growth of beneficial microorganisms in the soil, which can further enhance plant growth and protect against pests and diseases.
