Citric acid infiltrates and weakens or kills microorganisms through direct antimicrobial effect, lowering the Product's pH-level thereby combatting microorganisms, and through sequestration. However, use of multiple inoculation through crop specific microbial consortium, especially AM-based consortium in combination with nutrients (organic or inorganic in nature) provided a much better option in fruits with an added element of much better labile pool of microbial (taxonomic, function, and metabolic diversity) and nutrient pool of the rhizosphere for stronger soil carbon sink ultimately. Both plants and microorganisms obtain their nutrients from soil and change soil properties by organic litter deposition and metabolic activities, respectively.
