Duckweed thrives off nutrients and grows best when the water contains higher levels of nitrogen and phosphate (Wedge and Burris 1982). Check out some recent scientific papers about Azolla's green potential! According to a study by the UN’s Food and Agriculture Organization (FAO), duckweed acts as a nutrient sink — absorbing primarily nitrogen, phosphorus, calcium, sodium, potassium, magnesium, carbon and chloride from waste matter. Growth rates of pigs on different levels of duckweed meal are shown in Table 7. Wolffia globosa, a tiny, rootless duckweed, or water lens, apparently has what it takes to achieve great things, report scientists. Chlorophyll concentration was determined as described with modification. Dr. Bugbee for his passion for plants and environmental instrumentation. While our hypothesis was not proven to be correct through this experiment, other studies have found conclusive data on the effects of temperature with duckweed. S.Vanitha, NVN.Nampoothiri, C.Sivapragasam, Anitha M. e. non.M. When the warm conditions return the duckweed will return to the surface of the water (Wang and Messing 2012). Briefly, after fresh weight measurement, the duckweed plants were … The research was carried out at Texas Tech University to utilize duckweed species as part of a system for recycling cattle wastes from feedlots. Conclusion Literature In conclusion, the results of the experiment were pretty close to what was hypothesized: If duckweed is exposed to various levels of pH, its growth will be closely correlated with how close the pH level is to 6 Although the duckweed living in the petri dish But the best thing about duckweed is that it is also edible for humans.

A handful of studies have concentrated on using duckweed merely as toxicity indicators of aquatic environments (Tront et al., 2007; Saygideger et al., 2004) and a few of these studies have used duckweed to identify sentinel species. We generated this hypothesis due based on the fact that duckweed needs sunlight to gain the nutrients it needs to survive, and warmer climates commonly have more sunlight to help the growth and reproduction. Advances across the board in duckweed genomics, physiology, microbiomes, ecosystems and ecotoxicology, nutrients and natural products, biofuels and biomass production, will make up the subject matter and scientific content of the symposium. a toxic herbicide ‘ Glyphosate Each beaker was labeled with different colored tape to differentiate the beakers.
