  2. Algal nutrient solution - Wikipedia

    en.wikipedia.org/wiki/Algal_nutrient_solution

    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. Nutrient solutions, as opposed to fertilizers, are designed specifically for use in aquatic environments and their composition is much more precise. [2]

  3. Ocean fertilization - Wikipedia

    en.wikipedia.org/wiki/Ocean_fertilization

    Adding urea to the ocean can cause phytoplankton blooms that serve as a food source for zooplankton and in turn feed for fish. This may increase fish catches. [54] However, if cyanobacteria and dinoflagellates dominate phytoplankton assemblages that are considered poor quality food for fish then the increase in fish quantity may not be large. [55]

  4. Algaculture - Wikipedia

    en.wikipedia.org/wiki/Algaculture

    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 ...

  6. Algae - Wikipedia

    en.wikipedia.org/wiki/Algae

    Algae can be used to capture fertilizers in runoff from farms. When subsequently harvested, the enriched algae can be used as fertilizer. Aquaria and ponds can be filtered using algae, which absorb nutrients from the water in a device called an algae scrubber, also known as an algae turf scrubber. [129] [130]

  7. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    Eighty per cent of the mined phosphorus is used to make fertilizers. Phosphates from fertilizers, sewage and detergents can cause pollution in lakes and streams. Over-enrichment of phosphate in both fresh and inshore marine waters can lead to massive algae blooms which, when they die and decay leads to eutrophication of freshwaters only.

  8. Seaweed - Wikipedia

    en.wikipedia.org/wiki/Seaweed

    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.

  9. Reactive oxygen species production in marine microalgae

    en.wikipedia.org/wiki/Reactive_oxygen_species...

    Since iron is necessary for phytoplankton growth, the auto-reduction of reactive oxygen species may be a way for algae to get usable iron from free or organically bound ferric iron. [73] For instance, Cakman et al. [ 74 ] showed that ROS may increase the amount of iron available through extracellular ferric reduction.
