it's a very informative thread indeed.i am a regular follower of that.
but dada, I already have 12kg of gravel (2mm-4mm). they call it chini Dana at galiff.
how much more should I get?
next, u mentioned your combos with mostly sand or sand gravel.won't it get compact over time which might hamper healthy root growth.
should I cure vermi before use? if yes,then what is the procedure.
should I mix soil with vermi and Laterite??
and then mix it with 8 mm gravel.then cap it with 0.5 inch of coarce sand.at the top 1.5-2 inch of gravel.Is it a viable idea to prevent leaching of vermi- laterite- soil mix???
in this way can the compaction of soil be prevented???
Thanks a lot for ur inputs....
