University of New Hampshire scientists said a common aquatic plant called duckweed could help filter polluting runoff from dairy farms and so-called manure lagoons. They are investigating how ...

The food and fuel that farms itself Date: April 1, 2025 Source: Cold Spring Harbor Laboratory Summary: Scientists have released new and more accurate genome sequences for five species of duckweed.

The nutrients in the waste water also lead to quicker growth of the duckweed which could be used as a protein-rich feed for livestock. Hywel Dafis, who has 400 dairy cows on a farm in Talgarreg ...

With Wales' 500,000 cows each producing 50kg of waste a day, could duckweed be the answer? ... By growing duckweed on the farm, waste nitrogen and phosphates are taken out of the water, ...

Duckweed consumes nitrogen, phosphorous, calcium and iron, making it a potential source of remediation not only for the lagoons in which farm waste accumulates, but any type of wastewater.

Under the right conditions, duckweed essentially farms itself. Wastewater, ponds, puddles, swamps—you name it. If there's enough sunlight and carbon dioxide, the aquatic plant can grow freely.

In an effort to decrease nitrate-nitrogen levels in waterways, Southeast Missouri State University's David M. Barton Agriculture Research Center in Gordonville has set up a bioreactor -- an ...

But for the biofuel industry, the growing focus on duckweed is probably a good thing; in the future, what was a watery pest may provide a viable way to work yet another part of the planet's ...

Second, duckweed can thrive in agricultural pollution from, say, pig and poultry farms—potentially cleaning up some of the nitrogen and phosphorus such farms release into the water. Credit ...

Before the water can leave a 179-acre field on the farm, it is pumped into the bioreactor. It is a 360-foot-long, earth-covered trench filled with wood chips.
