Considered the smallest flowering plant on the planet, duckweed isn’t your typical weed.
Although it’s still termed invasive, research has consistently shown that this aquatic plant has more benefits for the environment than we probably know.
What is Duckweed?
Duckweed, also known as common duckweed or water lentils, is a rapid-growing aquatic plant that forms large mats on still or slow-moving water.
They are considered invasive plants because they can adapt to any environment, double their mass in a matter of days, and quickly colonize a body of water.
Duckweed is found in all continents except Antarctica.
The Power of Duckweed in the Environment
Set aside the invasive nature of duckweed that comes to mind and you’re in for a surprise on what these small plants can do.
Here are the benefits of duckweed for the environment:
1. Natural Water Purifier
Duckweed can maintain the clarity of water bodies by absorbing excess nitrogen and phosphorus, which are responsible for murky waters.
Environmentalists are now focusing on leveraging industrial-scale duckweed cleanup of wastewater from agriculture and sewage works.
2. Carbon Sequestration
Think of duckweed as the mini-forest on the frontlines of climate change.
Their sheer numbers allow them to absorb huge amounts of carbon from the air, making their giant, yet unnoticed, mark in fighting for our planet.
3. Enhances Aquatic Habitats
Duckweed’s blanket-like mats offer shade and shelter for smaller pond-dwelling species.
They also deter unwanted algae growth and mosquito breeding, providing a balanced and safe aquatic habitat.
4. Sustainable Food Source
The plant is known as a valuable food source for fish in aquaculture farms, however, it’s also incorporated into diets for animals such as pigs and poultry.
Its high-value protein can also be exploited as a protein supplement for the industrial production of ruminants such as cows and goats.
5. Sustainable Biofuel and Fertilizer
Duckweed could be the green fuel we’ve all been waiting for! Scientists have successfully found a sustainable way to convert the plant into sustainable biodiesel for transportation and heating.
The plant’s ability to grow on wastewater and absorb nutrients such as phosphorus provides another benefit for the environment, a green and sustainable fertilizer.
With essential fertilizer production resources dwindling globally, duckweed may be one of the viable alternatives available.
The next time you see duckweed in your pond or a nearby swamp, remember this mini powerhouse is highly beneficial for your environment in many ways.
