Dear Babak Malekian, I have used EM with some success but not under high pH and EC. I have the suggestion of using Sulfur for high pH looking to get soil pH about 7 to 7.3 and no more. In addition gypsum to reduce sodium saturation. I believe some great results can be gotten with mycorrhizal fungi through inoculation tests. There are quite a few commercial products out there. If you can make sure that the transplants are well colonized your field and garden results should improve. I would also suggest using mature compost at the planting site as part of your strategy. Sincerely, Paul Reed Hepperly
