In a given quantity of soil, there is a given amount of nutrients. Unless the microorganisms can add extra nutrients (K, N, P and trace elements) to the soil (not counting nitrogen fixing microbes) it will not increase the soil’s nutrient quantities. Althought they may or may not increase the rate of nutrient depletion by the plants, they certainly cannot improve the soil's quality in terms of nutreints.
Therefore I have a hard time understand the following:
“---------------in ways that can improve soil quality, enhance crop production and protection, conserve natural resources, and ultimately create a more sustainable agriculture and environment------------------“

I'm not sure the exact answer to your question, but I do know that adding organic matter and microorganisms benefits soil. I moved into a brand new housing complex, the top soil that was brought in was very poor. 2 years of improvements has seriously benefitted the quality of soil.
