All About Seaweed Fertiliser

Seaweed Fertiliser

There is evidence that Celtic and Scandinavian farmers have used seaweed fertilisers for centuries. Farmers noticed that the plants thrived faster in places that were fertilized with algae. Seaweed fertiliser is a fertilizer of organic origin that contains extracts of seaweed obtained from the ocean.

This fertilizer primarily improves the health and immunity of plants. Also, the seaweed fertiliser contains nutrients, minerals, and vitamins. They are rich in micronutrients such as nitrogen, potassium, and magnesium. This fertilizer has been used by gardeners who want to avoid using chemical fertilizers and those who do not wish to use it from animals such as cows, sheep, horses, chickens, etc.

Seaweed fertilizer can be in liquid, powder, or granular form. The most commonly used seaweed fertilisers come in liquid form due to the properties of rapid degradation and absorption by plants.

Where and How to Use Seaweed Fertiliser

Seaweed fertiliser is entirely organic and natural so that it can be used for all purposes, from lawns to orchards. The effect of applying this fertilizer is noticeable on all plants, while it will be mostly seen on those plants that have a greater need for nutrients.

It is crucial to understand the application of this fertilizer. Modern plant protection products such as many fertilizers come in tiny packages.

Namely, modern fertilizer technology is produced in high concentrations for more accessible transport, application, and the like.

The application of this fertilizer varies significantly from different purposes (ornamental plants, lawn, orchard, etc.) to the type of plant. Not all plants have the exact nutritional needs, so the concentration of this fertilizer is applied differently.
