Algae Covered Pond. Algal nutrient solutions are made up of a mixture of chemical salts and seawater. [1] Sometimes referred to as "Growth Media", nutrient solutions (e.g., the Hoagland solution, along with carbon dioxide and light), provide the materials needed for algae to grow.
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
Marine and aquatic biomass tentatively demonstrates high yield while requiring minimal use of arable land. Major advantages of algae are: no competition with food crops for arable land, high growth rates, and low fractions of lignin which reduces the need for energy-intensive pretreatment and compatibility with biorefinery approach implementation.
Other seaweed may be used as fertilizer, compost for landscaping, or to combat beach erosion through burial in beach dunes. [54] Seaweed is under consideration as a potential source of bioethanol. [55] [56] Seaweed is lifted out of the top of an algae scrubber/cultivator, to be discarded or used as food, fertilizer, or skin care.
A soil ball with indigenous worms in soil amended a few weeks previously with bokashi fermented matter. Bokashi is a process that converts food waste and similar organic matter into a soil amendment which adds nutrients and improves soil texture. It differs from traditional composting methods in several respects. The most important are:
The algae, especially some species which contain over 50 percent oil and a lot of carbohydrates, can be used for producing biodiesel and bioethanol by extracting and refining the fractions. The algae biomass is generated 30 times faster than some agricultural biomass, [15] which is commonly used for producing biodiesel.
Foliar applications of seaweed fertilizer extract have been shown to improve the uptake of nitrogen, phosphorus, potassium, and sulfur in soybeans such as Glycine max. [59] Research has also demonstrated that brown algae seaweed extracts can improve tomato plant growth, overall crop yield, and resistance to environmental stressors. [60]
Ascophyllum nodosum is an autotroph, meaning that it makes its own food by photosynthesis, like other plants and algae. The air bladders on A. nodosum serve as a flotation device, which allows sunlight to reach the plant better, aiding photosynthesis. [6] Epiphytic red algae on knotted wrack at Roscoff, France
