Seaweed extract is a naturally derived product from nutrient-dense marine algae (seaweed) that can enhance plants and has been used in agriculture for many years, similar to how millets have been used in Indian kitchens to nourish crops in a gentle, chemical free way. Seaweed extract for plants contains growth hormones, trace minerals, and natural enzymes which support soil health, increase plant immunity, and stimulate root growth and flowering.
Each millet variety has different health benefits and so does each variety of seaweed extract.
1. Kelp Extract (Brown Seaweed): Kelp is one of the better known forms of liquid seaweed extract and is full of natural cytokinins and auxins. Kelp encourages root growth, facilitates nutrient uptake and aids the recovery process when your plants become stressed due to severe heat or dry weather.
2. Red Seaweed Extract (Carrageenan Source): Red seaweed extract can provide antioxidants and trace minerals that augment cell integrity and disease suppression. Red seaweed can be helpful if you want to strengthen immunity and tolerance in your field crops of fruits and vegetables.
3. Green Seaweed Extract (Ulva and Sea Lettuce): Green seaweed extracts encourage chlorophyll development and higher levels for photosynthetic capacity. With this type of seaweed extract, crops can provide more yield as leaf area and enhance quality control by promoting color and robustness in the plant.
4. Blended liquid seaweed extract: In many cases, products may consist of two or three species of seaweed to help balance nutrient contents to create a wider complement of synergy and combinations. Blended seaweed extract can provide better potential in terms of product efficacy at all developmental stages of crops, from seedling, green leaf, flowering and flowering with harvest.
Introduction to Seaweed Extract and Its Importance
Like millets are a natural gift for baby food, seaweed extract is nature’s booster for plants, soil, and even human health.
Seaweed extract is made from marine algae (like kelp) that has been a part of human nutrition and healing in many cultures for thousands of years. Seaweed looped up in blue, green, or brown with a good source of nutrition is now seeing mass popularity for farming, skin care, and wellness due to its nutrient density, eco-friendly nature, and versatility.
What Is Seaweed Extract and How Is It Made?
Seaweed extract is liquid that is made from a variety of types of seaweeds, primarily brown algae like kelp, Laminaria, or Ascophyllum nodosum.
Seaweed is harvested from clean ocean waters and processed to make an extraction using a cold or heat extraction method. The result is any selection of liquid or powder with:
- Natural growth hormones (cytokinins, auxins)
- Trace minerals (magnesium, zinc, boron)
- Amino acids and vitamins
- Plant support enzymes and antioxidants
The most common and popular format is liquid seaweed extract. Liquid seaweed extract is the easiest to apply, the fastest to react, and is compatible with organic and conventional farming systems.
