How Seaweed Extract Is Used in Horticulture and Agriculture Products
Recently, seaweed extract has been increasingly embraced as a sustainable and eco-friendly alternative or addition to chemical fertilizers. This substance is derived from various seaweed species. It is also a natural and can be an organic source (if harvested from organic sectors) of essential minerals, vitamins, and trace elements that foster healthy plant development and enrich soil quality.
In this article, we will explore everything you need to know about seaweed extract in the horticulture and agriculture industries.
Seaweed Extract in Agriculture and Horticulture Products
Seaweed and kelp extracts are widely recognized and utilized in horticulture and agriculture. They are frequently applied to vegetables, fruit, turf, trees, ornamentals, and flower crops to fortify frost resistance and facilitate seed germination.
Most seaweed extracts employed in agriculture come from brown algae, especially Ascophyllum nodosum, which is abundant in the intertidal region of the Northern Hemisphere. Brown seaweeds contain substances that aid in boosting plant resistance to different environmental pressures, such as drought, salt, and extreme temperatures.
The Alkaline Extraction
Alkaline extraction is a popular technique used to extract seaweed extract from Ascophyllum nodosum. This method utilizes Potassium carbonate (K2CO3)or Potassium hydroxide (KOH) to break down the cell walls of the seaweed and release the beneficial bioactive compounds.
Removing any debris or impurities is the first stage in the extraction procedure. The seaweed is then heated to a precise pH level and temperature and mixed with an alkaline solution. After extraction, the mixture is neutralized with an acid to prevent an alkaline reaction. Lastly, the residual particles are filtered out of the solution.
Seaweed Extract Products
Most products are offered in both organic-use (OMRI) and non-organic variations. OMRI-listed seaweed extracts undergo a stringent certification process to meet the required standards. Moreover, the raw materials utilized in producing organic use seaweed extracts must be natural, and the extraction process must be free of synthetic chemicals and other harmful substances.
On the other hand, products that do not have an organic label may incorporate synthetic chemicals, preservatives, or additives. These products are still widely used, however, they are incompatible with organic farming or gardening practices.
The products are normally available in liquid and soluble powder forms. The liquid form is popular due to its versatility and ease of use. It can be sprayed straight onto the plant or mixed with irrigation water. Meanwhile, soluble powder products are designed to dissolve in water for easier application. They are suitable for large-scale farming or gardening operations.
Types of Application Method
Seaweed extract products can be applied to plants and crops through various methods, such as irrigation or foliar. Irrigation refers to blending seaweed extract with water and administering it to the soil or root zone through irrigation systems. This approach enables the plants to consume the advantageous components via their roots, which can foster robust root development.
Foliar application is a spraying method of applying seaweed extract directly to the plant’s leaves. The plant absorbs the beneficial compounds through the leaves, improving the plant’s ability to withstand stress. This technique is commonly used to prevent diseases and insect infestations or to address nutrient deficiencies.
