Duckweeds could be a rice companion plant!
What the duckweeds do. They clean the water, provide bio-fertilizer, allege control, and limit mosquitoes. These are things that humans are not able to control without adding chemicals. Also, duckweeds contain high amounts of protein, more so than soy bean. Duckweeds are a good food resource in some parts of Asia for both animals and humans. Duckweeds spread quick, colonies of them could cause a problem of oxygen. But, don’t worry, other good friends working together in the water.
In Korea, we call Keguri Bap (duckweeds), means 'Bullfrog’s rice'. A lot of time bullfrogs live in the rice paddies. The duckweeds are extremely dense on the surface of the water that when they swim out of the water, their face is covered with duckweeds. So, it looks like bullfrogs are eating the duckweeds. That’s how we named it? In Korea, while the little children are eating rice and if they leave some rice on their face, the parents say ” You have bullfrog’s rice on your face”. I love the sound of word 'Keguri Bap'.
