This article completely glances over the fact that most of the fixed nitrogen is in urine (should be kinda obvious with “urea” ) and not the solid manure. Same goes for potassium and other dissolved plant nutrients.
This is a waste stream that is very much underutilized and currently processed at immense cost in waste water treatment plants.
Given this very obvious oversight, you can probably already guess the quality of the other points made…
Weve replaced the nutrient cycle with a drain to waste system unfortunately , our cities commingle out urine with toxic waste in the sewerage systems and its not economically recoverable.
Iiving rural its illegal to use and probably near impossible to legalize.
so its accessible only to rural outlaws, its not a systemic solution and still leave N deficits that have to be made up for with synthetic fixation.
