Seaweed aquaculture contributes to climate change adaptation by damping wave energy and protecting shorelines, and by elevating pH and supplying oxygen to the waters, thereby locally reducing the effects of ocean acidification and de-oxygenation. Farmed seaweeds act as a temporary forest, providing food and shelter for small aquatic animals and fish. As a soil conditioner, seaweed fertilizer can improve the physical qualities of soil, such as aeration and water retention. Clay soils that lack organic matter and porosity benefit from the humic acid and soluble alginates found in seaweed. At present it's thought seaweed stores around 175 million tonnes annually of carbon, or 10% of the emissions from all the cars in the world. The possibility seaweed could join other blue carbon storage in mangroves and wetlands as a vital tool in the fight to stop climate change. Thus, seaweeds play an essential role in the food webs of saltwater ecosystems through photosynthesis and primary production, which translates into a rise in the production of fish, abalone, sea urchins, and other animals consumed by humans. Due to this, seaweed farming is viewed as ecologically sustainable and beneficial because of its inherent positive environmental characteristics, such as its ability to add oxygen to water and filter seawater of excess nutrients, offering solutions to such problems as terrestrial agricultural. Providing a food source, both directly, for grazing species such as sea urchins and indirectly by releasing organic matter into coastal waters; and. providing spawning grounds and nursery grounds for juveniles.

Seaweeds contribute to carbon sequestration, coastal safety, carbon sink, food security, and the control of ocean deoxygenation and acidification; therefore, seaweed is remarkably regarded as a promising blue carbon adaptation and climate change mitigation strategy. At present it's thought seaweed stores around 175 million tonnes annually of carbon, or 10% of the emissions from all the cars in the world. To many scientists, this suggested the possibility seaweed could join other blue carbon storage in mangroves and wetlands as a vital tool in the fight to stop climate change. Here's how it's supposed to work. Seaweed has been removing carbon dioxide from the atmosphere for at least 500 million years. A type of seaweed known as kelp is being developed for its nutritional value and its ability to absorb and lock away huge quantities of carbon dioxide. Seaweed absorbs CO2 more effectively than trees. It also improves water quality by extracting harmful nutrients such as nitrogen from the sea.

Some liquid seaweed fertilizers may be applied as foliar feeds, where the nutrients are sprayed onto the foliage and taken up through the leaves. Fresh seaweed, or dried and processed seaweed products are not true fertilizers because their plant nutrient content is not guaranteed or standardized.The seaweeds contain organic matters and specific nutrient content that stimulate plant growth. It was also shown that adding up different seaweeds in sufficient quantities enhanced soil conditions and growing parameters in field harvests. Seaweed Fertilizers functions as an organic bio-fertilizer. Because seaweed is rich in micro and macronutrients, Humic acids, and phytohormones, it enhances soil fertility. Seaweed fertilizers have the broadest range of benefits to plants beyond plant nutrition. They also promote bacterial activity in soil mediums. I addition to enhancing stress tolerance, nutrient uptake, growth, and yield, seaweed-based biostimulants have also been shown to help reduce seed dormancy and enhance root systems, flowering, fruit quality, and taste and even the quality of produce.Farmed seaweeds act as a temporary forest, providing food and shelter for small aquatic animals and fish. One study found 73% more species in our seaweed farm compared to the surrounding sea. Seaweeds are rich in nutrients, such as fibre, iodine and vitamin K, and have been an important source of food, animal feed and fertilizer for coastal communities for thousands of years. Seaweed fertilizers are organic plant feeds containing extracts of seaweed sustainably derived from the ocean. Ascophyllum nodosum is a variety particularly renowned for its ability to boost overall plant health. Containing beneficial nutrients such as magnesium, potassium, nitrogen and more.

Seaweed also offers coastal protection via wave reduction, and it can enhance fish production and marine biodiversity. It's also great at capturing carbon. In fact, seaweed captures up to 20 times more carbon per acre than terrestrial forests. Seaweed could play a vital role in the sustainable future of our planet; it has a low carbon footprint, doesn't require fresh water, needs minimal land-based infrastructure, and can be used in a number of industries aside from food, including agriculture, cosmetics and pharmaceuticals, and as a biofuel. The seaweeds create forage and refuge habitat for commercially important fish and diversity of marine life. Seaweeds also act as a sponge soaking up what's in the water. These marine plants could potentially be cultivated to reduce heavy metals and other coastal pollutants.
