Scientists are hoping duckweed and slurry could help farmers "make money from muck".

A new project hopes to provide low-cost animal feed while stopping livestock waste polluting rivers.

Duckweed, a protein-rich water plant, has been described as a "miracle plant" as it is one of the fastest growing on the planet.

There are around 500,000 dairy cows in Wales which excrete about 50kg (110 pounds) of waste each per day.
