  2. Algal nutrient solution - Wikipedia

    en.wikipedia.org/wiki/Algal_nutrient_solution

    One outcome is the manifestation of algae blooms or eutrophication, primarily triggered by runoff from land sources. This leads to an excessive nutrient influx, fostering the overgrowth of algae. Upon the decay of these algal blooms, bacteria consume a substantial amount of dissolved oxygen, depleting oxygen levels in the water.

  3. Biofertilizer - Wikipedia

    en.wikipedia.org/wiki/Biofertilizer

    Since a bio-fertilizer is technically living, it can symbiotically associate with plant roots. Involved microorganisms could readily and safely convert complex organic material into simple compounds, so that they are easily taken up by the plants. Microorganism function is in long duration, causing improvement of the soil fertility.

  4. High-nutrient, low-chlorophyll regions - Wikipedia

    en.wikipedia.org/wiki/High-nutrient,_low...

    Algae grown in floating farms could be harvested and used for food or fuel. All biological life is made up of lipids, carbohydrates, amino acids, and nucleic acids. Whole algae could be turned into animal feed, fertilizer, or bio-char. Separating the lipids from the algae could also create bio-diesel from the lipid content and bio-char from the ...

  5. 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. Iron fertilization - Wikipedia

    en.wikipedia.org/wiki/Iron_fertilization

    Ocean iron fertilization is an example of a geoengineering technique that involves intentional introduction of iron-rich deposits into oceans, and is aimed to enhance biological productivity of organisms in ocean waters in order to increase carbon dioxide (CO 2) uptake from the atmosphere, possibly resulting in mitigating its global warming effects.

  7. 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]

  8. 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.

  9. Diazotroph - Wikipedia

    en.wikipedia.org/wiki/Diazotroph

    So it does not require extreme conditions and specific catalysts in fertilizer production. Therefore, produce available nitrogen in this way can be cheap, clean and efficient. Nitrogen-fixing bacteria fertilizer is an ideal and promising biofertilizer. [12] From the ancient time, people grow the leguminous crops to make the soil more fertile.
