Seaweed biostimulants

Exploring the eco-friendly potential of seaweed-derived solutions in agriculture

As the importance of sustainability and ecological food production increases, the appeal of biostimulants, especially those derived from seaweed, is on the rise. These natural products from the sea are gaining attention as a more environmentally conscious choice compared to traditional, oil-based biostimulants.

Biostimulants, in general, are most impactful during the initial growth phases of plants. Among the varieties of seaweed, sugar kelp (Saccharina Latissima) is noted for its potential sustainability and environmental benefits compared to others such as kelp (Laminaria Digitata) and knotted wrack (Ascophyllum Nodosum). This is primarily due to the cultivation methods that some companies employ, which ensure the preservation of wild seaweed populations and minimize disturbance to marine life. Sugar kelp is known for its rich nutrient profile, which might include higher levels of specific nutrients beneficial for plant growth and yield improvements when compared to other species. These nutrients can include:

  • Essential macronutrients like nitrogen (N), phosphorus (P), and potassium (K) that support plant growth and development.
  • Vital micronutrients such as iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu), required in trace amounts for plant health.
  • Organic compounds, including amino acids, which are the protein's building blocks, and natural plant hormones that could positively influence plant growth and development.

The production of biostimulants from seaweed is typically considered more environmentally friendly compared to the production of oil-based alternatives, which involves extracting raw materials from fossil fuels with potential negative environmental and climatic impacts. Seaweed-derived biostimulants are sourced from sustainable marine harvesting, contributing to marine conservation and reducing reliance on non-renewable resources.

Opting for biostimulants as an alternative to synthetic fertilizers hints at a move towards more sustainable gardening and agricultural practices. These biostimulants have the potential to enhance soil quality,  plant resilience to stress, and diminish the necessity for artificial fertilizers and pesticides, contributing to more environmentally sound and potentially economically advantageous agricultural practices.
