Get Ready to Eat Pond Plants
Meet the amazing azolla, a nutritious fern that grows like crazy, capturing carbon in the process. Could it be a food—and fertilizer and biofuel—of the future?
Testing for polyphenolic content, Winstead found this azolla to have much, much lower levels than other species, actually more in line with the mainstay fruits and vegetables Americans eat. Not only does azolla provide lots of free nitrogen, but the plant cover helps suppress weeds and reduces the emission of methane, a far more potent greenhouse gas than CO 2. It’s been used for thousands of years to feed cows and chickens, and still is, says David Hughes, founder of PlantVillage, which is using technology to help farmers in Africa adapt to climate change.
