  1. NARDC's Aquaponics yield and variety trials at Nanniode.. this is what we have this season. I am feeling a wee bit better today than over the past week or so. Noteworthy new stuff under aquaponics sand culture trials are the carrots, pumpkin, and colocasia bog filter (last picture). Arka Rakshak Tomatoes under a very old trial are now being removed and replaced with stevia, strawberry, cauliflower, various amaranthus, spinach, and beets. FYI.. We at NARDC intends to provide direct unbiased yield comparisons and results of our various heirloom vegetables and hybrid varieties/species produced in many different aquaponics sand culture environments, irrigation, nutrient distribution, plant scheduling, fish/feed input schedule, balanced fish growth, risk management, etc. Hopefully NARDC's legal status would soon be confirmed (fingers crossed) and most of our data will be posted online soon after that. I appreciate all our followers. Thanks for following NARDC's facebook page "aquaponicsfuturist."
  2. Dear all, I have created this topic to document our own IAVS progress and findings.. In brief, we have over 2+ years of hands-on experience working with various commercial-scale Aquaponics systems.. media beds, NFTs, DWCs, etc. We are now building our first batch of sand beds believing in the IAVS vision. This is to apply as an extension to our current systems. Next, I will update you the progress with some pictures. I look forward to your support. Please share your questions, comments, suggestions.. Thank you.. Kind regards, vkn
  3. And this Weekend high from Chennai! In their own words, "The first ever trial of corn in Circle of Life Aquaponics is a success. This is the first harvest, 20 mins ago. Amazingly perfect golden sweet corn. Weight of this ear of corn is 340 gms."
  4. Received this from Team Circle of Life Aquaponics, Chennai. I hope you all would like it. They are now 4 months old and their best stories are yet to come.. Let us wish the team all the best!
  5. I wish you all the best. Three years is a long time. I am sure you may have learned quite a bit. Dont you think it is high time you apply your knowledge gathered, start an aquaponics system for yourself and then share your experiences. What is stopping you in starting a small unit for yourself?
  6. Arun, aren't you the one who is also following my FB profile and FB group? Good to see you choose to asking questions here. I have also read your recent aquaponics 'teaching' bouts at FB which is interesting. Volume to volume is about 1:1.5. Starter stocking density for tilapia I follow in my projects is as usual 100 fingerling fish per 1000L. I am currently traveling and do not recollect the exact length of this biofilter. I guess it is about 14 meters or so.
  7. Not really clay, they are dug up and shaped using the same native earth.
  8. Earthen aquaponics is in the making at Thodupuzha.. Both the floor and side walls of these aquaponics sand biofilters are being made of native earth. An another replication of NARDCs low-cost commercial aquaponics build design, considering the labor costs alone for the construction, we accomplish a significant development cost savings in this project as well. Here is a picture. More later. We haven't given it a business name yet.. Any suggestions are welcome.
  9. Poles made of bamboos or any other wood are used as stakes in between. You can use galvanized iron also. Usually the bird's net over larger pond is done in summers here when water level is low or when pond is dry.
  10. Hi Cecil, I use a thick nylon bird's net to ward off similar birds from our aquaponics fish culture tanks. Your pond is slightly big but it is very much doable in large areas as well. Just thought this would help before your Form 37 gets you a killing licence..:)
  11. Nsidibe, hearty welcome to APN and to my thread here. Time has become the scarcest resource to me these days. So many things to do and so little time.. My suggestion would be to ask lots of questions and participate in the forum discussions. Who has the time to read and reply lecture kind of questions. Ask one question at a time? Or, two if they are related. Not more than that at any given time. Having your own thread at APN to share your practical experiences would greatly help you and others too. I wish you all the best.
  12. Working on a new project this month. Build area is 400 m2. Rain/sun shelter protected cultivation to boost sustainable year-round aquaponics food production is a low-cost alternative to greenhouse/polyhouse farming in India. Here is a picture update.
  13. Rooted plant cuttings.. This is the first time we trial Stevia rebaudiana plant in aquaponics sand culture..
  14. Amazing work! WOW!
  15. For lunch today.. Here is a one-year-old snakehead fish from our aquaponics system at Nanniode. This is part of the second yield trial we began an year ago.
  16. Thanks Joe. I was being careless.. just didn't zoom in to find those blue crosses. Reading through to understand more of it. Thanks for the highlights of your interesting work. Very true.. I could relate that to our own old farm and working with nature - cows, goats, hens, rabbits, quails, etc. where animals roam free-ranging. Dad was focusing on planting trees mainly for shade and timber. Later they became coconut, banana, guava, and cocoa groves as far back I can remember.
  17. Some nice landscape pictures there, Togaji.. All I could find were a few blank templates. Could you briefly say what were your inferences from your report? It would help.
  18. Yes, very interesting Ande.. Not yet finished reading but it looks like Savory holistic techniques are almost similar to what these scientists have been doing in the name of Silvopasture at CEFS (The Center for Environmental Farming) www.cefs.ncsu.edu, the intentional mixture of trees and pasture, integrating Agriculture and Forestry. What do you think are the differences?
  19. FYI..Our Malaysian Aquaponics dreams might come true soon..Just received the completed paperwork, signed NDA document, etc. as part of the due diligence. Anyone from Malaysia here in our forum?
  20. One of my good friends here in India at a potato research station has been growing potatoes using aeroponics techniques. However, their focus has been on seed production. They have been my inspirations for our own aquaroponics experiments and the continued yield trials of high value Chinese potatoes. Here is one of their papers. I hope it helps you some way in your pursuits. https://www.researchgate.net/publication/308874872_Aeroponics?ev=auth_pub
  21. JFYI.. We at NARDC are celebrating our fifth anniversary of micro-focusing on aquaponics tomorrow. Here is sharing with you a banner we made for the day, hoping someone reads this at our forum. I would like to thank you very much for having me here. Your feedback is highly appreciated; it will help us to improve our ability to serve others in India. Kind regards, vkn
  22. Someone wanted to see the root of a plant growing in aquaponics sand culture..here is a portion of it.
  23. Bllooming Innocence water lily in Aquaponics koi sump tank.. With pure white petals, it stands high above the water. @Circle of Life Aquaponics, Chennai
  24. For lunch today..assorted red/green amaranth and bottle gourd from our Easy trial systems. Chinese potatoes are on second yield trial with spacing and feed rate changes.
  25. Mike/Ande, I know this is a late response but then if I were to choose, I would take 20% of #12, 60% #18, 20% of #35 and then mix it thoroughly. I am not saying that some other particle size distribution will not work. This arrangement really is helping in lateral water movement.
