What are the biostimulant properties of seaweed extracts in plants?
Seaweed biostimulants enhance plant growth, nutrient uptake, stress tolerance, and soil health through the synergistic effects of bioactive compounds. Various application methods, including foliar spraying, soil amendment, seed priming, and fertigation, are discussed for improving crop resilience and productivity. Seaweed extracts are able to act as biostimulants affecting plant growth, biochemical composition, and yield, eliciting a plant defense response [9] , which in turn assists the plant in resisting salinity, drought, and other stresses [10].Limited nutritional profile: Despite being rich in trace minerals and plant hormones, most seaweed extracts tend to have a low content of nitrogen, phosphorus, and potassium-major nutrients, or what is more often called NPK. Risk of salt buildup: Seaweed extract contains salt by nature.Seaweed Extract is a natural stimulant that promotes healthy tissue regeneration in plants. This extract imparts added strength to crops, fortifying their structure and resilience.Seaweed functions as an organic bio-fertilizer. Because seaweed is rich in micro and macronutrients, humic acids, and phytohormones, it enhances soil fertility.Enhanced Growth and Stress Tolerance: Studies show that seaweed extracts can stimulate rooting, enhance chlorophyll content, and improve stress tolerance (Ferrante et al. Rasul et al.
What is the use of seaweed extract in plants?
Seaweed extract contains amino acids and vitamins that aid in the synthesis of proteins and enzymes, facilitating overall plant growth and vigor. These are called ‘phytostimulatory’ properties that allow for faster and optimal plant growth. Seaweed is rich in trace elements (nutrients that plants only need small amounts of) including iron, manganese, zince, copper and boron, which are often lacking in common fertilisers such as Growmore and fish, blood & bone, but which are nevertheless important for plant health.Laminaria japonica The scientific name for seaweed extract can vary depending on the species of seaweed being used. Commonly-used varieties include *Laminaria japonica*, *Ascophyllum nodosum*, and *Fucus vesiculosus*.Seaweed extracts are considered biostimulants in agriculture, as they promote growth and defense responses to plants. Brown seaweeds is the class of macroalgae which have been used as a biomass source to produce seaweed extracts [11].Plants that don’t like seaweed fertilizer tend to be those that thrive in low-nutrient soils. For example, drought-tolerant herbs such as lavender, rosemary, and other Mediterranean herbs do not benefit from the nutrients provided by seaweed and prefer leaner, well-drained soils.Seaweed (Marine algae) extracts have been reported to be beneficial to plants for early seed germination, better plant growth, improved crop yield, and also in preventing biotic and abiotic stress.
What bioactive compounds are in seaweed?
As pharmaceuticals, seaweeds are rich sources of bioactive compounds like polysaccharides, protein compounds, pigments, and polyphenols, which have demonstrated various pharmacological activities such as antioxidant, antibacterial, anti-inflammatory, antiviral, anticoagulant, and potentially anticarcinogenic effects. Seaweed Extract is a liquid fertilizer that is 100% organic, extracted from seaweeds which contain more carbonates and nitrates.Seaweed extract contains amino acids and vitamins that aid in the synthesis of proteins and enzymes, facilitating overall plant growth and vigor. These are called ‘phytostimulatory’ properties that allow for faster and optimal plant growth.Uses of Seaweed Extract For Plants Generally, natural seaweed extract is mainly used for seed soaking, foliar spraying, and soil application. Foliar spraying is a common fertilization method in plant production.Farmed seaweed is also an ingredient in cosmetics, animal feed, and fertilizer. Seaweed farms absorb nutrients and carbon dioxide to grow. The farms can help improve water quality and buffer the effects of ocean acidification in surrounding areas.Brown seaweeds are the most used of the seaweeds in agriculture, and the base for most commercially available liquid seaweed extract products. Ascophyllum nodosum: Brown seaweed collected from the North Atlantic Ocean that is rich in natural plant growth hormones (cytokinins, auxins), mannitol and trace elements.
Which plants benefit from seaweed?
Seaweed plant biostimulants have been shown in hundreds of studies to improve root development, synchronize fruit sets, accelerate flowering, increase yields, and improve drought and stress tolerance in plants or crops such as marigolds, soybeans, broccoli, chili peppers, watermelons, shallots, corn, tomatoes, and . Seaweed contains auxins and cytokinins that promote root growth and new shoot growth. Enzymes that introduce greater photosynthetic rate and energy production within the plant. Trace elements such as iron, magnesium, and zinc introduce a natural defence mechanism for the plant.Here’s what you need to know: Broad compatibility: Liquid seaweed fertilizer is generally safe for most plants, including herbs, vegetables, and flowers. Its organic and gentle nature makes it a versatile choice for various gardening needs.Seaweed is a high nitrogen and potassium, fast acting liquid fertiliser which contains additional seaweed. The combination of a high concentration of nitrogen and potassium encourages top growth and increases stress tolerance.Because seaweed is rich in micro and macronutrients, humic acids, and phytohormones, it enhances soil fertility. In addition, seaweed-derived fertilizers contain polysaccharides, proteins, and fatty acids which improve the moisture and nutrient retention of soil, contributing to improved crop growth.
What is the name of seaweed extract?
Benefits Seaweed Extract (Ascophyllum Nodosum) It increases the count of the microbes in the soil that can invoke nitrogen from the air. Solve the soil salinization effectively caused by over fertilization. Improves germination of seeds and enhances the root growth and development. The common macronutrients that present in seaweed extracts include calcium (Ca), magnesium (Mg), phosphorus (P), sodium (Na), potassium (K) and sulphur (S).Therefore, the combined application of seaweed and humic acid to rapeseed can improve salt tolerance and increase growth, as well as antioxidant enzymes that mitigate damage caused by salinity stress.In this study, when both treatments were compared, it was found that the seaweed + humic acid application was more effective in reducing the effects of stress.Seaweed extract contains amino acids and vitamins that aid in the synthesis of proteins and enzymes, facilitating overall plant growth and vigor. These are called ‘phytostimulatory’ properties that allow for faster and optimal plant growth.What potential of seaweed extracts as a biostimulant for improving salt stress tolerance of solanum lycopersicum?Seaweed extracts (SWE) increased chlorophyll levels in tomato under salt stress. SWE mitigated salt stress by enhancing enzymatic antioxidant activities. SWE reduced salt stress by improving non-enzymatic antioxidant activities. Tested SWE can be used as biostimulant to improve salt stress tolerance of tomato. The common macronutrients that present in seaweed extracts include calcium (Ca), magnesium (Mg), phosphorus (P), sodium (Na), potassium (K) and sulphur (S).Additionally, naturally high levels of iodine in some brown seaweed can be particularly harmful to foetuses and the young so pregnant and breastfeeding women, and children, should not eat seaweed.Seaweed is rich in essential nutrients such as nitrogen, phosphorus, potassium, and trace elements like iodine, iron, zinc, and magnesium. These nutrients benefit healthy plant development, promoting robust root growth, improved flowering and fruiting, and overall plant vigor.Seaweed is rich in trace elements (nutrients that plants only need small amounts of) including iron, manganese, zince, copper and boron, which are often lacking in common fertilisers such as Growmore and fish, blood & bone, but which are nevertheless important for plant health.Seaweed polysaccharides isolated from the cell walls of various species of algae, possess immunomodulatory, anti-inflammatory, antiviral, antitumor, antithrombotic, anticoagulant and antioxidant bioactivities. Within the group of polysaccharides extracted from algae there are the phycocolloids.
