You bring up an interesting point about these rejuventors. To my knowledge, they are advertised to improve the soil by breaking down crop residue faster in order to increase nutrient availability. I am not aware of any University research that has looked at these products in depth, so I am unable to provide specifics about the cost-efficiency and payback of these products.
I would suggest talking with a local University Extension Agent about the particular product you are interested in trying.
