  1. So I have inquired about the soil texture: Texture of most soil to be excavated: Clay: 20-25% Silt: 30% Sand: 35-40% Gravel: 5-10% Does that help someone to give me an idea of time/m3? Can the vacuums move the soil from one point to another instead of just into the barrel? I need to place it nearby and then move it back once I am done with the tree. Thanks
  2. You might want to get a phone from India or China. Most of them come with two sim slots(dual sim phone). Normal brands such as Samsung, Lenovo etc... Both sims are active for phone at all times so you choose which one to use when you call. It doesn't matter who you are with; the network operators work independently. Numbers can be made to forward to another number when the other is not reachable so if one sim has reception people should be able to reach you even if the other has no reception. Mobile internet only works on one sim at a time though but I think that may be changing. https://www.mysmartprice.com/mobile/pricelist/dual-sim-mobile-price-list-in-india.html
  3. Thanks, all pits will be worked on with wet soil so I guess this will be ok. Its almost like stone when dry. Digging bars go in about 2 cms at a time then.
  4. Thanks for the reply. 1-2 days with the hgv mounted vac or just with the airspade? I am, so far, thinking of using an airspade 2000, 105 cfm or 150 cfm 4ft barrel, with this: 55 Gallon Single Venturi Static Conductive Drum Vacuums GUARDAIR.COM Powered by compressed air, Guardair 55 Gallon Static Conductive Drum Vacuums are ideal for vacuuming up chips... It all depends on what I can source and the price. India has limited choice for this sort of stuff.
  5. Is that with a soil extractor? I just checked the soil volume from the pic that I posted above. It is 20m3... So we are looking at 20 to 40 hours per tree, assuming not extra difficulties...That is a lot. Anyone have experience with clayey soil? Cheers, Island
  6. Thanks for the reply. Its certainly more on the clayey side but no stones. I really need to refine my soil understanding. Soil here is often zero to 20 cms of sandy loam topsoil followed by clayey homogenous soil. Here is a typical section: Shared album - Island Lescure - Google Photos PHOTOS.APP.GOO.GL
  7. Thanks Craig Johnson! So I guess the main question is: how much time does it take to remove 1m3 of soil from the ground going around roots? Cheers!
  8. Thanks! Good point about moving the soil out. Are you familiar with any particular extractor that would suit? I had a look and cannot find much. Only thing in India so far is this: Compressed air for the mining industry - Atlas Copco WWW.ATLASCOPCO.COM Robust, energy-efficient and safe mining air compressors and blowers for all mining applications. Perform in the harshest... I haven't contacted them yet but I might be better off getting something from the UK or US as it may not be available here. Any links or search words welcome please. Cheers, Island
  9. root exploration drawing.dae Hi, Depth would be till extent of roots so it really depends. I imagine that we wont be going further than a meter down in general. Width would be a quarter of a circle (the canopy being the circle) but up to RPA radius. So again, generally I would assume max 10 meters out but less deep as we go out. Roots will be deeper closer to the trunk and less so farther out no? Soils would be mainly (I am not yet certain of the structure of these but will find out): Laterite Soil: The term is derived from the word 'Later' which means 'brick'. Laterite soil is found in those regions of the country which receive heavy rainfall with alternate dry and wet period - particularly, near the coasts. This kind of soil becomes soft when wet and hardens when dry. In these climatic conditions, leaching of soil takes place which is a process in which fertile portion of the soil gets washed away by heavy rains. They are formed from the decomposition of rocks and contain iron oxide which gives them red or pink colour. This type of soil is normally deficient in nitrogen and is poor in lime content; it is an acidic soil. and Alkaline Black cotton soil: Characteristics of Black Soils A typical black soil is highly argillaceous [Geology (of rocks or sediment) consisting of or containing clay] with a large clay factor, 62 per cent or more. In general, black soils of uplands are of low fertility while those in the valleys are very fertile. The black soil is highly retentive of moisture. It swells greatly on accumulating moisture. Strenuous effort is required to work on such soil in rainy season as it gets very sticky. In summer, the moisture evaporates, the soil shrinks and is seamed with broad and deep cracks. The lower layers can still retain moisture. The cracks permits oxygenation of the soil to sufficient depths and the soil has extraordinary fertility. Thanks for the help! root exploration drawing.dae
  10. Hi, I am writing a project to inspect root systems of trees to prove photographically that they are shallow (generally) in India. Could someone with experience give me an idea of how long it would take to dig with an airspade to say a meter by a quarter of a tree's root system? The idea is to dig within only a quarter of a mature tree's root system so as not to strain it. The trees would be 10- 15 meters tall, canopies similar to sycamores of that height. Any ideas, research or experience related to this also welcome! Thanks! Cheers, Island
  11. Sure, if you are into it! I just want a depiction in a slightly more understandable form really. She will then draw it to suit the style present in the rest of the book. No specific time-frame. Still lots to do. As it turns out, making a 15 page children's book takes a lot of work... Below is an example of the theme and the draftsmanship. Cheers, Island
  12. So attached is probably the worst picture I have ever drawn but it is just to convey that I am looking for this sort of drawing to show to a friend who is illustrating a children's book for me. I would like this to be in it in some form. I have seen this somewhere but cannot remember where. Anyone know where or have a nice drawing of it please? Just to be clear: it is depicting what happens in a tree's growth where one tree grows on itself and then again and again till death... Thank you, Island
  13. Was there the other day 🙂 https://photos.app.goo.gl/RpsTdGJQin5a24Yu8 It's actually made of lots of pieces of wood (maybe driftwood) stuck together. This is one of many really cool sculptures there. Amazing place: Gardens by the Bay.
  14. Ya we teach both. To give people more perspective but also because ddrt is still more widely accepted. We climb on srt though.
