Seaweed Extract

Basic Product Introduction

Seaweed extract is functional organic water-soluble fertilizer refined from deep-sea macroalgae such as Ascophyllum nodosum, kelp and Sargassum via low-temperature enzymatic hydrolysis, biological fermentation and concentration. It is rich in seaweed polysaccharides, alginic acid, mannitol, betaine, natural plant growth regulators (cytokinin, gibberellin, abscisic acid), humic acid, amino acids, potassium, calcium, magnesium, boron, zinc and other active nutrients. Fully water-soluble and highly compatible, it can be applied via foliar spray, drip irrigation, soil flushing, seed soaking and root drenching for field crops, fruits, vegetables, fruit trees, seedlings and Chinese medicinal herbs. Feed-grade seaweed extract can also be added to livestock and aquafeed in small doses.

Core Nutritional & Functional Advantages

1. Natural endogenous plant hormones for bidirectional growth regulation

It contains natural auxin, cytokinin and gibberellin, milder than synthetic hormones without phytotoxicity:

• Stimulate root growth and branching at seedling stage, strengthen seedlings and avoid excessive vegetative growth;
• Boost flower bud differentiation and retain flowers & fruits during blooming period;
• Accelerate dry matter accumulation for uniform fruit expansion at fruit swelling stage;
• Delay leaf senescence and prolong harvest period in late growth stage.

2. Powerful rooting & root repair to raise seedling survival rate

Seaweed polysaccharides activate root meristem to generate massive capillary roots and fibrous roots; repair damaged roots caused by fertilizer burn, pesticide phytotoxicity and low-temperature frost damage, shorten seedling recovery time after transplanting and revitalize weak/stunted seedlings rapidly.

3. High-activity alginic acid improves soil, relieves compaction and accumulates organic carbon

As high-molecular organic colloid, alginic acid promotes soil crumb structure formation to loosen heavy clay; adsorbs soil heavy metals and degrades chemical fertilizer residues; chelates immobilized phosphorus, potassium and trace elements in soil to raise fertilizer utilization rate by 25%–40%; alleviates soil acidification, secondary salinization and continuous cropping obstacles in greenhouses.
