Product Detail

This plant seaweed extract organic NPK fertilizer is an eco-friendly agricultural nutrition product integrating organic seaweed active ingredients and balanced macro nutrients. It takes natural deep-sea kelp as core raw material, processed via low-temperature biological extraction technology to retain abundant alginic acid, seaweed polysaccharides, betaine and natural plant growth regulators inside seaweed. Different from single chemical NPK fertilizers, this product combines organic components with nitrogen, phosphorus and potassium elements, realizing dual supply of slow-release organic nutrition and quick-acting mineral nutrition.

After being absorbed by crops, seaweed active substances can stimulate cell activity of roots, leaves and flower organs, accelerate root hair germination, expand the nutrient absorption area of plant roots, and effectively alleviate poor growth caused by continuous cropping, soil hardening and saline-alkali land. The matched organic NPK formula supplies stable nutrition in the whole growth cycle, promotes uniform seedling growth, dark green leaf color, neat flowering and stable fruit setting.

The product has good water solubility with few insoluble impurities. It can be fully dissolved in clean water for multiple fertilization methods including foliar spraying, drip irrigation, sprinkler irrigation and root flushing, adapting to both open field planting and modern intelligent greenhouse cultivation. The organic mild formula will not cause chemical damage to crops, and can coordinate with most common insecticides, fungicides and medium trace element fertilizers for combined application to save fertilization labor cost.

Long-term regular application helps increase organic matter content in soil, optimize soil aggregate structure, activate beneficial microbial activity in soil, and continuously improve soil fertility. It also strengthens crop resistance to adverse environments such as low temperature, drought and saline alkali, reduces physiological fruit drop and improves fruit surface luster and taste quality.

Produced under standardized production flow, every batch undergoes strict laboratory detection to control organic matter content, seaweed extract activity and nutrient index. We adopt 10kg and 25kg PP bags with inner PE liner for moisture-proof storage and long-distance transportation. Neutral OEM packaging is supported, and complete export qualification documents such as quality inspection report and MSDS are available to meet the import customs requirements of various countries.

ECHEMI Editorial Reference

Alginic acid is a tasteless, practically odorless, white to yellowishwhite, fibrous powder. Alginic acid found in the walls of brown seaweeds (Phaeophyceae) consists of D-mannuronic acid units and L-guluronic acid units probably linked β (1->4). The chains contain three distinct regions; in one, the D-mannuronic acid units alternate with L-guluronic acid units, whereas the remaining regions are homogeneous and contain either D-mannuronic acid or L-guluronic acid.

Water Solubility:

Insoluble in water.

Storage Conditions:

Alginic acid hydrolyzes slowly at warm temperatures producing a material with a lower molecular weight and lower dispersion viscosity.
Alginic acid dispersions are susceptible to microbial spoilage on storage, which may result in some depolymerization and hence a decrease in viscosity. Dispersions should therefore be preserved with an antimicrobial preservative such as benzoic acid; potassium sorbate; sodium benzoate; sorbic acid; or paraben. Concentrations of 0.1–0.2% are usually used.
