gas tanker is it really worth it for what 20.00 for some organic line of soil then to have a world of hurt or problems in your next grow dont matter to me i will never reuse my soil have tryed it before and seen loses in yield you can't sell me on it i own a botanic garden center family owned you think we save our soil if people don;t buy our plants not likely nor will anyother botanic garden
Here in Cali, where we have amazing soil for cheap, yards of good amended soil go for $40-$65/yard. You say you go through 140 yards - that's $5,600-$9,100 you would save in soil costs. If you are buying per pallet then you would save much more than this.
Every botanic garden I know composts. What state do you live in?
And what are you trying to prove, other than you personally can't seem to recycle soil?
OP's question - Is it possible to recycle soil?
Your answer - I tried and failed so now I throw away 140 yards of soil on a regular basis, fields of corn in poorly drained areas have salinity problems, here are pictures of my bud. I said I don't recycle soil!
Notice how you don't address the initial question? Just talk about yourself and your personal situation? Is this helpful?
