Wholesale Price Sodium Alginate 25KG: For Fertilizer

Sodium alginate powder is a valuable agricultural input that enhances soil quality, improves seed germination, and increases fertilizer efficiency. Its ability to retain moisture and facilitate slow nutrient release makes it an essential component in modern farming practices, particularly in areas prone to drought and soil degradation.

What is Sodium Alginate?

Sodium alginate is extracted from brown seaweed, specifically from the cell walls of algae like kelp. It’s a linear polysaccharide composed of repeating units of β-D-mannuronic acid (M) and α-L-guluronic acid (G). Sodium alginate cas number 9005-38-3, is off-white crystalline powder, dissolves readily in water, forming a viscous solution. As a botanical fertilizer additives supplier GREEN AGRI offers customers FOB Price.

And now you know!

Today, grind and process brown algae extract sodium alginate into crystalline powder and extract forms for use in various products, such as agriculture and food. Since sodium alginate has GRAS (generally recognized as safe) status, experts consider these products safe.

Source and Manufacturing Process

Brown seaweed, particularly species like Laminaria, Ascophyllum nodosum, and Macrocystis pyrifera, naturally produces sodium alginate, which manufacturers extract as a polysaccharide. The extraction process involves the following steps:

Harvesting and Cleaning: Collect brown seaweed and wash it thoroughly to remove impurities.

Alkaline Extraction: Treat the seaweed with an alkaline solution (such as sodium carbonate) to break down the cellular structure and release alginic acid.

Precipitation and Purification: React the extracted alginic acid with sodium carbonate or sodium hydroxide to form sodium alginate.

Filtration and Drying: Filter the solution and spray-dry the purified sodium alginate into a fine powder for agricultural use.

Seedling Cultivation and Soil Application

Sodium alginate is widely used in seedling cultivation and soil improvement due to its ability to enhance soil moisture retention and promote plant growth. Including:

Soil Conditioner: Sodium alginate improves soil structure by increasing water retention and aeration, helping roots absorb nutrients efficiently.

Seed Coating: When used in seed treatment, sodium alginate forms a protective film around seeds, improving germination rates and resistance to drought stress.

Root Development: The polysaccharide properties enhance root elongation and stimulate microbial activity in the soil, creating a more favorable environment for plant growth.

Fertilizer Carrier: Sodium alginate helps slow down nutrient release, improving fertilizer efficiency and reducing nutrient loss due to leaching.

Seedling Cultivation Soil Benefits

Enhances the soil’s ability to retain moisture, preventing excessive drying of young seedlings.

Encourages the proliferation of beneficial soil microbes, aiding in nutrient breakdown and uptake.

Improves soil porosity, allowing proper root aeration and reducing the risk of root rot.

Reduces soil erosion and nutrient leaching, creating a stable environment for early plant development.

Formula and Dosage

The recommended dosage varies depending on the crop type, soil conditions, and application method:

• Soil Application: Mix 0.2%–0.5% sodium alginate powder with organic fertilizers or directly into the soil to improve soil moisture retention and microbial activity.

• Seed Coating: Dissolve 0.5% sodium alginate in water and soak seeds for 12–24 hours before planting to enhance germination rates.

• Foliar Spray: Prepare a 0.1%–0.3% sodium alginate solution and spray on plant leaves to boost stress resistance and improve nutrient absorption.

• Hydrogel Application: Combine sodium alginate with calcium chloride to form a hydrogel that can be used in arid regions to retain soil moisture for extended periods.

Safety

Sodium alginate is non-toxic, biodegradable, and environmentally friendly. It does not pose risks to humans, plants, or soil microorganisms. It is approved for use in organic farming and sustainable agriculture due to its ability to improve soil health without causing pollution or chemical residue buildup.
