Alginic Acid is a natural bio-stimulant fertilizer refined from deep-sea brown kelp via low-temperature enzymatic extraction, presented as fine soluble powder with high purity active alginic acid polysaccharides. It contains natural plant auxins, cytokinins, mannitol and oligosaccharides, zero harmful heavy metals and chemical residues, fully meeting global organic agricultural standards. As a multi-functional organic fertilizer raw material, it features strong water retention, ion chelation and soil activation capacity. It effectively improves degraded saline-alkali and compacted soil, boosts nutrient absorption of all crops, and widely applies to fruit trees, vegetables, field grains, cash crops, flowers and greenhouse planting. Compatible with NPK, medium and trace element fertilizers, it serves as core additive for base fertilizer, foliar fertilizer and fertigation, a sustainable green input for ecological agriculture.
Alginic acid molecules carry abundant carboxyl groups with super water-locking ability, absorbing 200–300 times its weight of water to optimize soil aggregate structure, relieve soil hardening and reduce irrigation frequency. It acts as natural chelator to bind solidified iron, zinc, magnesium in soil, turn unavailable mineral nutrients into absorbable forms and raise fertilizer utilization rate greatly. Rich bioactive substances stimulate root hair proliferation, strengthen seedling root system and prevent weak seedlings; meanwhile boost chlorophyll synthesis to thicken leaves, enhance photosynthesis and alleviate leaf yellowing. It activates crop self-defense enzymes to lift resistance against drought, cold, salinity and fungal diseases, reduce blossom and fruit drop, promote fruit uniform expansion, coloring and sugar accumulation to upgrade crop taste and commodity valuePMC. It supplies carbon source for rhizosphere beneficial microbes to balance soil microecology and mitigate continuous cropping obstacles. Fully water-soluble, suitable for soil spreading, hole application, drip irrigation and foliar spray; packed in 25kg moisture-proof woven bags, stable quality during sealed storage and convenient for bulk transportation. Long-term application cuts chemical fertilizer dosage and lowers agricultural residue risks.
Alginic Acid fertilizer is an eco-friendly multi-effect bio-stimulant with soil conditioning, root boosting, stress resistance and quality improvement functions. It solves common planting pain points including compacted saline soil, low nutrient availability, weak root system and poor crop stress tolerance. With natural marine organic raw materials, wide crop adaptability and excellent mixing performance, it increases yield while optimizing agricultural product quality, cuts fertilizer investment and supports pollution-free organic planting. Stable indicators and complete bulk supply system make it an irreplaceable premium functional additive for modern high-efficiency green agriculture.
