The article is great....really speaks to the soil food web elephant in the room. but then closes with accounting, said SOC elephant, little weight beyond 3.66 X elemental carbon. The compost & compost tea focus, the 74% NH3 savings, 110,000 plant chemical signals, speaks elegantly to what husbandry of wee-beasties can achieve.
The Meta-Study on Syn-N Research conducted on the Morrow plots, that Barry Hayes mentions in the article, I cite often myself. Even with crop genetics being pushed to concentrate sugars in above ground biomass, that study by Illinois and ISU settled the SOC question.
