The benefits of Seaweed in plant fertilizers

Seaweed And Plants

The relationship between plants and seaweed has always been well known commercially, however from a plant science perspective, the multiple benefits this natural growth hormone provides is kept quiet. Covered in this article is how seaweed and the plant world go hand in hand, to work together on a symbiotic level.

What Are Cytokinins, Auxins And Gibberellins?

Used as a biostimulant in many modern day commercial grow nutrients, seaweed is packed full of beneficial trace elements as well as rich in naturally produced plant hormones. These hormones consist of auxins, cytokinins and gibberellins. Used to provide growth signals to the plant and aid in the development from seed germination until harvest. Used at the very earliest stage of growth and produced within the root zone, these three hormones naturally found in seaweed, play a massive role in the life span of the plant.

What Exactly Do They Do?

At molecular level cytokinins play a huge role in sending biological signals to the plant, which determine the growth and development of cell division. Produced in the roots, seeds and fruits, travelling upwards towards the xylem, to promote lateral growth and to slow down the symptoms of ageing and keeps the plant’s leaves green for longer time. As well as performing mitosis, the development of chloroplast, root cell tissue, the structure of branching and leaf formation. The way the cytokinin works is by binding itself to a protein receptor within the cell membrane, which will then be attached to a phosphate group in the cytosol. The protein will then activate once moved into the nucleus, where it binds to the genes of the plant which will dictate what direction of growth will commence.

Auxins are a group of plant hormones. These Auxins promote plant growth above ground but also promote the production of roots and root hairs. Auxins also regulate the growth of fruits and flowers.

Gibberellins are what determine stem growth as well as flower and fruit development. Sometimes used as a way of nursing old stubborn seeds, gibberellins can stimulate dormant seeds by producing an enzyme that will supply the seed with some nutrient energy. This is then transferred into the roots then upwards to the growing tips. As with everything too much of these three hormones can in fact inhibit plant development. Providing too much auxin can restrict and stunt root growth, too much gibberellin can in fact reduce germination rates in seeds and excess amounts of cytokinin can burn plant leaf tissue.

Organic certified Seaweed as ingredient in Cellmax products

Now we know the all the powerfull benefits of seaweed for plants. We also need to mention the downside of this beautifull ingredient. Seaweed is a natural filter of the sea. over time, mankind has seriously polluted the sea, which means that seaweed in the sea is needed more than ever. it is therefore important that seaweed is harvested responsibly and properly treated so that all the harmful substances in this natural filter ultimately do not reach your plants. This is also the advantage of seaweed, because seaweed contains a wide range of trace elements that plants can use again when they grow and bloom.

a few products from Cellmax contain Certfied Organic Seaweed because of the amazing properties we explained in this article. The Cellmax Rootbooster and BIO-Rootbooster both contain a lot of Seaweed extracts and this is why these products have a very strong odour that can smell like soj sauce, or rotten fish.

Like the name suggests the Cellmax Alga-Max is a pure seaweed algea extract that is enriched with Phosphorus and Potassium. Alga-Max accelerates flower and fruit production because of the P205 and the K20. While the seaweed extracts aid in plant resistance againt heatstres and provides the neccesary Natural plant growth hormones.

Finally the Cellmax Flowerstimulator also contains small traces of Seaweed.

Tip: Rootbooster as a Foliar Spray

Applying a fine mist of Rootbooster mixed with water (at 2ml/L dillution) on the tops and undersides of leaves, can be extremely beneficial in the vegetative stage of the plant. In fact, this even increases final yield.  Not only is Rootbooster as foliar application an instant treatment of natural hormones and algae, it will also improve the water retention within the leaf as well as the building process of cell walls. Excellent to treat stress or the open wound of a plant, applying a foliar spray can allow for a better uptake of nutrient and drastically improve vigour. Adding a mild solution to a spray bottle will deliver best results and always ensure that you are feeding on both sides of the leaf.

Studies And Research

Below is an short testament taken from the studies of Cadi Ayyad University /Department of Biology, Laboratory of Biotechnology, Valorization and Protection of Agro-Resources, Morocco. Here studies have proven the effects of seaweed on the bean plant, used for farming in Africa.

The seaweed extract application on bean plant (Phaseolus vulgaris c. v. Paulista) enhanced the vegetative growth at lower concentrations 25% of Fucus spiralis and 25% of Ulva rigida that was found to have maximum influence, on growth parameters as shoot length and root length. When Seaweed liquid extracts (SLE) applied by foliar spray or incorporated in the medium with the Hoagland nutrient solution under hydroponic system, biochemical parameters such as chlorophyll pigment and proteins content were also enhanced when compared to untreated bean plants. High proportions of seaweed extract in medium culture (100% of Fucus spiralis extract; 75% and 100% of Ulva rigida extract) were found to show negative effect. The examining of nitrate reductase activity showed that foliar application of seaweed extract increased this enzymatic activity.”
