  1. 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.
  2. 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.
  3. 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?
  4. 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?
  5. 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
  6. 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
  7. Someone wanted to see the root of a plant growing in aquaponics sand culture..here is a portion of it.

  9. 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.
  10. 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.
  11. I am sorry Ande. Not done yet. I have several video clips.. will collate one for you.
  12. We had gone live on this new project recently. Here is a Live video, FYI. https://www.facebook.com/vk.narayanan/videos/10154493130267091/
  13. Thought you might like this panoramic photo of 'circle of life' project @ Honeyland Aquaponics Sholinganallur, Chennai. This is what we could complete in about 10 days and where we are as of today. Click/zoom to enlarge and move around.
  14. Aufin, Neem oil seems to be a good choice in managing nematodes. Let us know how your trials went. I have been using it as a diluted foliar spray for various pests as a general purpose insecticide, miticide, fungicide, etc. Even if it drips a bit in the sand beds, there are no adverse effects seen for most all fish. Some fish like climbing perch were found sensitive to it and we saw some mortality. There could be other reasons for that episode though. I forgot to say you can also use Marigolds (Tagetes spp) as a companion plant. They are known to repel/suppress/reduce soil nematodes naturally. Planting them densely before two months of introducing host plants such as tomatoes is another option.
  15. Are you sure they are nematodes? I have not observed any nematode infestations in our sand culture yet. However, I am asking the operators to closely examine the plants especially those growing in older beds to look out for yellowing of leaves, smaller leaves, less yields, stunted growth, etc. They may have come through infested sand (river/beach sand), nursery saplings (used directly without removing potting mix), or soil attached to tools used elsewhere, etc. Sanitation is important. One of the many reasons, I use gravel in the pathways as mulch to the soil surface around the beds and not allow any visitors to step on the bed walls (seen people doing it), etc. Management of it organically is quite difficult in soil culture as nematodes spread everywhere easily. Soil farmers try to reduce infestations by fallowing, crop rotation (not very effective), soil solarization, etc. You may want to try solarization in your sand beds. One way to do it is to moisten the bed and cover it with a translucent plastic tarp for about 6 weeks during hot summer. This would kill all your nematodes. I am sure there are better/quicker ways to tackle your situation. What do others think? 'Circle of Life' project is shaping up well and we are equally excited in seeing its go live in about 2 weeks from now. Good news is it is going to be all sand culture/iAVs. No other growing techniques are deployed here. I will update the status.
