Alternative Fertilizers?

Interesting article in the Wall Street Journal from April 30th (link) highlighting the hesitancy of producers to switch from the tried and true traditional fertilizers for cheaper unproven alternatives - the article highlights Pivot Bio microbes.

In the current inflationary environment producers have been more willing to try out small acre amounts on these new products. More information on Pivot Bio (WSJ article link + website link).

Do these alternatives fertilizers work? How do they stack up against popular synthetic fertilizers? Are Canadian producers interested in these alternatives, or are we afraid to make changes in fears of yield drops?
