The liquid inoculum contains a consortium of efficient microorganisms (10 to power 8-9 CF U).The soil was contaminated 4 years ago. The soil is clay loam, pH above 8,with low content of N,P and organic matter.
Hello Awad
if you can adjust your soil moisture and add a source of substrate either chemical ( e.g. Urea) or organic substrate (e.g. animal manure) that would substantially enhance the removal rates of indigenous soil microbial. Use either land-farming or co-composting technology as your first approach to clean-up your soil. Need some articles to read see some of my attached work. Hope that could help you!!!!
Good luck in your work
Hi Awad.
You can follow the advice of former colleagues. You can use bioaugmentation, a microorganism or plant endemic. However, you can add agroindustial residues as coffee husk and bagasse, which serve as organic substrate and "donor" of microorganisms for contaminant remotion, given the concentration of the contaminant you mention, is a good process with considerable time and can be exploited for soil improvement. If you like you can go to this link and access my own research about it, plus some other interesting process for you. Success. Regards

Hi Awad,
I agree to all the answers that are given earlier. I would suggest you to find a suitable substrate and run a small pot experiment to see the survivability of your organisms in the experiment. The factors that may affect may be the climatic condition and also the soil moisture content. The substrate that you are using must have the nutrients to support your organism. As pointed out earlier baggase or saw dust may be a good choice of substrate. Go for the cheap and easily available substrate.
Hope this helps you
I agree strongly with Karthik. You need to optimize the soil conditions first. pH 6.5 to 7.5, maintain moisture to ~60% field capacity, aerobic conditions need to be maintained, adequate nutrients (N,P,K,S) before you add any (if needed) microorganisms . You need to optimize the soil condition for microbial populations as well as plant growth. We have added compost to sites with success and the compost will aid in buffering the lower pH.
Good luck
