Duckweed

Duckweed is an aquatic plant found in marshes. It has a tremendous capacity for rapid growth, being able to double its mass in 24 hours!   Its nutrient composition depends on the availability of nutrients, and achieving up to 43% crude protein (dry-matter basis) is not impossible. Although it can contain about the same level of protein as soybean meal, for example, its high yield capacity means that it is possible to produce about 10 tones of protein per hectare per year, compared only to 1 ton
