Top 18 Best Seaweed Fertilizers in India: Benefits and Prices

Gardeners and farmers have used seaweed for plants for thousands of years. Seaweed fertilizer is an organic fertilizer from seaweed used in agriculture to increase soil fertility and plant growth.

Benefits of seaweed fertilizers

Seaweed fertilizer is usually a kelp-derived soil additive rich in micronutrients (also contains NPK content). It has been used for a long time, especially by farmers near the coast, and can be prepared in many ways. You can even add Kelp to the soil (but it may take some time to break down). In addition, seaweeds have cultural and ecological importance. They are valuable ingredients used in various traditional cuisines, and their production is a significant industry for many coastal nations.

Furthermore, seaweeds, including giant Kelp, provide food and shelter for other marine species. Additionally, due to their ability to convert carbon dioxide (CO2) into biomass through photosynthesis and their faster growth rates than land plants, they are critical players in carbon sequestration and the fight against climate change. Below are some of the benefits of seaweed fertilizers:

Improves plant vigor, root growth, and chlorophyll synthesis.
Promotes early flowering, fruit set, and fruit uniformity.
Prevents rancidity and extends product shelf life.
Improves nutritional quality.
Provides stress tolerance, drought, salinity, and frost.
Eliminates disease, bacteria, and fungi.
Helps control pests of insects and soil nematodes.

Price of seaweed fertilizer

India’s average market price of seaweed fertilizer is Rs 275 per kg.

What is Liquid Seaweed Fertilizer?

Liquid seaweed fertilizers are fertilizers derived from a natural source, seaweed. The making process involves collecting the seaweed, carefully washing the grass to remove some salt water, and finally letting the grass decompose in the water. The plant material is left in the water until it breaks down into a liquid or becomes quite a slurry. Kelp, a large brown seaweed, is a typical example of seaweed used in seaweed fertilizing.

Liquid seaweed is extracted from the fermentation of these leaves, and these extracts have been used for over a decade. Most seaweed fertilizers are kelp-derived and have rich soil amendments with plenty of micronutrients. They also contain an essential N-P-K factor that contributes to plant effectiveness.

Types of Seaweed Fertilizers

1. Liquid seaweed – I find liquid seaweed one of the best possible options for container growers. It makes it easier for plants to access the nutrients in the fertilizer produced by pressing and soaking the Kelp in water.

2. Seaweed/Kelp Meal – While seaweed is prepared by soaking liquid seaweed directly in water, seaweed meal is made by air-drying the seaweed or Kelp.

3. Seaweed extract powder – Seaweed extract powder is usually made by heating seaweed to remove all water content present. After heating, a solid material can be smoothed into a powder for use.

4. Calcified seaweed – Calcified seaweed is not an example of a seaweed fertilizer made from Kelp. It has a variety of calcified corals and some unique algae, all sourced from the sea. Generally, this variety contains about 50% of calcium and the usual minerals, which are very useful for plant growth.
