Blue-green algae is used as a biofertilizer. A biofertilizer is a substance containing living micro-organisms which, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant.

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.
Commercial and industrial algae cultivation has numerous uses, including production of nutraceuticals such as omega-3 fatty acids (as algal oil) [3] [4] [5] or natural food colorants and dyes, food, fertilizers, bioplastics, chemical feedstock (raw material), protein-rich animal/aquaculture feed, pharmaceuticals, and algal fuel, [6] and can ...
Scientists in attendance were interested in how harvesting algae could become a method to maintain and improve water quality. Algae to fertilizer: Harvester could help defend against Florida's ...
Other seaweed may be used as fertilizer, compost for landscaping, or to combat beach erosion through burial in beach dunes. [55] Seaweed is under consideration as a potential source of bioethanol. [56] [57] Seaweed is lifted out of the top of an algae scrubber/cultivator, to be discarded or used as food, fertilizer, or skin care.
Nutrient solutions, as opposed to fertilizers, are designed specifically for use in aquatic environments and their composition is much more precise. [2] In a unified system, algal biomass can be collected by utilizing carbon dioxide emanating from power plants and wastewater discharged by both industrial and domestic sources.
The seaweed was also used as fertilizer for crop land in the same areas in which it was harvested. [8] [Note 1] Fucus species can also be used for thalassotherapy, along with other species such as Turkish towel (Chondracanthus exasperatus), feather boa (Egregia menziesii), and finger kelp (Laminaria digitata).

Maerl has been extracted for centuries mainly for use as an agricultural fertilizer. The amount extracted increased in the late 20th century and in 2000, maerl was extracted at c. 5,000 tonnes per year in Ireland and c. 500,000 tonnes per year in France. [19] Large scale maerl extraction over the past 40 years has removed and degraded maerl ...
