2. Duckweed is the common name for any of 11 species of aquatic plant, known scientifically as Wolffia. A single root (or root-hair) protrudes from each leave. I’ve got some suggestions for your blog you might be interested in I’m not doing this to be contrary, but rather to bring out the truth. Aerobic bacteria thrive off increased oxygen levels, resulting in improved water quality and natural decomposition of organic matter—reducing duckweed and other plant life. Fact: Duckweed dies in marine ecosystems due to the salt content. Great post! So, duckweed using up oxygen in the water is not a myth. Out of interest do you know if Duckweed, or other nutrient greedy plants, can be used as a way to take nutrients out of ponds by letting it grow then removing the bulk of it over and over? These marvelous creatures do not need constant sun on them, so the filter of duckweed on the water might work to their advantage. In Thailand, the species used for huma… Additionally, that combined with the mat blocking out sunlight can result in the death of submerged vegetation which can have cascading effects on the rest of pond life. Duckweed (scientific name Lemna) is a small bright- green plant, about the size of a fat flake of oatmeal, which floats on top of water bodies. I loved as much as you’ll receive carried out right here. I’m copying text right out of articles I am finding on the Internet about duckweed “invasions.”  Here’s the real scoop: 1. A dense cover of duckweed on the surface of water inhibits both oxygen entering the water by diffusion and the photosynthetic production of oxygen by phytoplankton because of the poor light penetration. Fact: Living duckweed takes CO2 from the air and some from the water column. This small, cress-like weed can ‘carpet’ the surface of the water and choke off oxygen to other aquatic life, so it’s important to stop it taking hold. Fact: the grey water itself is an issue as well. It really depends on how clean the pond is at the start – I am sure that using rainwater rather than tap water would also dilute any nutrients from a ‘polluted’ pond. Add duckweed. Fact: Living duckweed takes CO2 from the air and some from the water column. The link didn’t show up as shown, so I went to the main site and found it at http://dspace.nehu.ac.in/handle/1/2035 Apparently, you can’t link directly to the article itself, but only to the lead-in, and then click on View/Open in the gray box. Alternatively, a water oxygenator can be used. (marine equals oceans, estuaries, etc…).” In tidal systems, duckweed that is flushed out to coastal and estuarine areas does die, but massive amounts of decomposing duckweed can decrease water quality. Wade, I WISH you were my next-door neighbor because I would take all your duckweed all summer long and be thankful for it. I live in a part of Thailand where duckweed has long been consumed by humans. Maybe that is what the writer is referring to. Of course, while duckweed may have its place in the laboratory or in the feeding trough, it doesn’t belong in your small pond. Here the range of animals is pretty much the same as we’ve seen throughout the year – including at those times when there was much more oxygen in the water. The low values in the Old Pond are pretty low - at this time of the year 12-15 milligrammes per litre would be about fully saturated. Thank you a million and please carry on the enjoyable work. Boaters can help reduce the growth of duckweed by using environmentally friendly cleaning products, such as Ecover, which do not contain the nutrients that the weed feeds on. Duckweed improves water quality, while algae causes taste and odor problems in water and can plug water treatment filters. Duckweed can invade ponds and bodies of water. This is absolutely true. It should be between 6 and 7.5. You’ll have a really clean pond, a beautiful garden (or happy chickens) and can rest assured that your pond is art. I suppose In fact, they are very real when managing duckweed in natural systems. And this makes me think about you and me. Does duckweed oxygenate water? I love duckweed. Thanks for your thoughts. Of course, while duckweed may have its place in the laboratory or in the feeding trough, it doesn’t belong in your small pond. Everyone says that duckweeds reduce the amount of oxygen in the water. BTW: Beauty is in the eyes of the beholder. Duckweed does not like moving water or windswept water even if the nutrients are high. Create a free website or blog at WordPress.com. The nitrate nitrogen removal in the pond Introduce Duckweed Predators. However, at night photosynthesis stops (because it requires light), but plant growth and tissue repair, which both require respiration to release energy, can continue. ( Log Out /  It also blocks wind action across the surface of the water, blocking the oxygen-transferring interface between the surface of … Apparently you’ve got some nutrient inputs that the duckweed are responding to, either from foliage or leaching waste nutrients from nearby fields, etc… Stop the inputs and let the existing duckweed remediate your pond. 1. This isn’t a myth in and of itself, but it cracked me up as it speaks to humans thinking that they are in charge of a natural process. ( Log Out /  I’m having problems locating it but, I’d like to send you an e-mail. What’s also interesting is that the New Pond currently has no submerged plants. i.e., for ammonia re-moval, there is no difference between original pond water and pond water with Duckweed. The New Pond is always  highest and the Old Pond, covered in duckweed, is lowest. ( Log Out /  Aquatic habitats have, in general, degenerated throughout the world because of pollution by both industry and other activities. A dense cover of duckweed on the surface of water inhibits both oxygen entering the water by diffusion and the photosynthetic production of oxygen by phytoplankton because of the poor light penetration. It also reduces water evaporation out of ponds helping to conserve water. Duckweed is naturally occurring and we shouldn’t fight it (unless it is taking over a water to the detriment of other plant and animal species, but that is usually a result of humans adding nutrients and disturbing natures delicate balance). It doesn’t use it up. Therefore, despite the duckweed drawing more oxygen from the water, unlike fish, the turtles can leave the water. to breathe. You are correct that duckweed absorbs CO2 and releases oxygen during photosynthesis. So, it is best to use eco-friendly cleaners which have reduced phosphorous. We’re closely monitoring the weed and it should disperse itself naturally. Duckweed on a pond helps prevent algae that causes bad-tasting water. Duckweed can grow in hard or soft water, and thrives in bright light, but will grow in low light conditions as well. I need to look more into the fact that duckweed can pull heavy metals and toxins from the water column. It is small and free floating and grows on the surface of still or slow moving water in carpet-like groups. It tends to grow in dense colonies and in still water quickly covers the entire surface of the water depleting oxygen and cutting out the sunlight that submerged plants need for their growth. By respire, I am referring to using oxygen to break down sugars and other molecules for respiration, to respiration in the context of using lungs etc. Nitrification of ammonia occurs within the aerobic root zone of duckweed. Anyway, I think you are doing a great job with your work, but some of what your said in this post was a little misleading. Each vertical bar covers a 24 hour period. You can grow duckweed indoors by following these simple steps: Buy about 50- 100 duckweed pods and place them in a container.
