Irish farmers and growers have long used fertilizers to make their crops grow faster and to prevent soil erosion.
But in recent years the fertilizers have become a major source of pollution in Irish waters, which also suffer from pollution from industrial chemicals.
Now, scientists at Trinity College Dublin have developed a new fertilizer made from algae that can be used to make fertilizers that are less polluting and to provide farmers with better water quality.
The research was carried out in collaboration with the US Food and Drug Administration and the Irish Ministry of Agriculture and Fisheries, according to a press release.
The research team found that the algae is a promising new source of biofuel for agriculture.
The algae can be grown in a water system that is more acidic and has higher levels of dissolved oxygen, which is needed for plants to grow.
This reduces the need for fertilizer and therefore can make fertilizer more efficient.
The researchers said the algae can also be used as a biofuel because it has a lower carbon footprint compared to traditional fertilizers.
The researchers found that their algae-based fertilizer has lower greenhouse gas emissions and that it can be more economically produced than conventional fertilizers by replacing other chemicals in fertilizers with algae.
