Alginate Oligosaccharides (AOS)
(IHUMATE AOS)
Ihumate Alginate Oligosaccharides (AOS): a premium 90% powder for agricultural biostimulant and fertilizer formulations. Targeted enzymatic hydrolysis of brown-algae alginate produces low-molecular-weight oligosaccharides with a degree of polymerization (DP) of 2–6. Their mannuronic (M) and guluronic (G) acid units and unsaturated end groups distinguish this defined AOS fraction from a broad seaweed extract. A 10–20% liquid option is also available for liquid formulation work.
For crops facing weak roots, uneven nutrient uptake, drought or salinity, AOS acts as a plant signaling elicitor that can support root development, leaf activity and natural defense responses. It fits foliar, drip and fertigation programs as well as fertilizer manufacturing. Use it alongside sound nutrition, irrigation and crop protection; confirm results under the local crop, water and stress conditions.
Why source through Ihumate? Clear powder and liquid grade selection, batch COA/TDS support, formulation compatibility discussion, 1–20 kg packing and OEM/ODM options help buyers build a consistent commercial product. The videos show the powder and its water-dispersion process. Packaging pictures are format examples only: printed text is not the guaranteed AOS specification or final label.

Frequently Asked Questions
1
How is AOS different from a conventional seaweed extract?
AOS is a defined, low-DP fraction obtained by targeted alginate hydrolysis. The 90% powder and 10–20% liquid can be specified by active content, while conventional seaweed extracts contain a broader mixture of components.
2
Can the 90% powder use the same field rate as the 10% liquid?
No direct rate substitution is provided. Field drip, furrow and foliar rates on this page refer to the 10% liquid. The 90% powder manufacturing rates are listed separately; establish powder field rates through formulation and local crop trials.
3
What is the research basis for root growth and defense signaling?
Wheat-root research reported nitric-oxide-associated root responses, while a tobacco study observed defense activation. Research observations do not guarantee the same field response in every crop.
4
Can AOS be blended into fertilizers?
It is suitable for evaluation in compound, organic and water-soluble fertilizers. Check pH, source-water quality, salt load and storage stability in a small batch before commercial production.
5
What are the packaging and shelf life?
The source specification lists 1–20 kg bags or drums and 12 months when sealed in a cool, dry place. OEM/ODM formats can be discussed; writing on illustrative packaging is not the product specification.
6
Are you a trading company or a manufacturer?
We are a professional manufacturing enterprise. Our modern factory is located in Huozhou, Linfen, Shanxi, China. With an annual capacity of 500,000 tons, we invite global partners to visit our facility.

Application & Dosage: Alginate Oligosaccharides (AOS)
Field rates below apply only to the 10% AOS liquid. Manufacturing inclusion rates for 90% powder are separate references. Pre-mix with clean water and verify compatibility before large-scale use.
Farm application: 10% AOS liquid
- Drip irrigation:Apply 1.5–3 kg/ha into the root zone after transplanting, during root recovery or at key nutrient-demand stages.
- Furrow fertigation and foliar spray:Furrow: 3–6 kg/ha at 2,000–4,000× dilution. Foliar: 0.3–0.6 kg/ha at 3,000–5,000× dilution; avoid hot, bright periods.
Fertilizer manufacturing: calculate by grade
- Granular organic and compound fertilizers:Per metric ton, reference 10% liquid at 2–3 kg / 3–6 kg, or 90% powder at 0.2–0.3 kg / 0.3–0.6 kg, respectively.
- Water-soluble fertilizer:Per metric ton, reference 10% liquid at 15–30 kg or 90% powder at 1.5–3 kg. Run dissolution, compatibility and storage-stability pilot tests.
Application Ratio Scheme
| Crop Name | Growth Stage | Application Ratio |
|---|---|---|
| 10% liquid (field) | Drip irrigation | 1.5–3 kg/ha |
| Furrow fertigation | 3–6 kg/ha; dilute 2,000–4,000× | |
| Foliar spray | 0.3–0.6 kg/ha; dilute 3,000–5,000× | |
| 90% powder (manufacturing) | Compound fertilizer | 0.3–0.6 kg/metric ton |
| Water-soluble fertilizer | 1.5–3 kg/metric ton |
Product Advantages: Alginate Oligosaccharides (AOS)
A defined low-DP AOS fraction and 90% powder grade support precise agricultural formulations for rooting, nutrient efficiency and stress resilience; field responses depend on crop and management.
1
Targeted enzymatic AOS
Brown-algae alginate is converted into DP 2–6 oligosaccharides; the 90% powder enables active-content-based formulation design.
2
Root establishment
Plant signaling responses can support root elongation and new root formation where slow establishment limits water and nutrient uptake.
3
Nutrient-use programs
Use with balanced NPK and irrigation to support nutrient uptake and leaf physiological activity in high-input crops.
4
Defense priming and stress response
AOS can stimulate plant defense and antioxidant pathways, supporting recovery from salinity, drought and temperature stress.
5
Ihumate supply support
Batch documents, formulation discussions, export coordination and OEM/ODM packing help align the ingredient with the buyer’s finished-product label.
