They sell that stuff "nitrohumus". I've used it about 28 (1982 I think) years ago in a 3' deep x 10" wide trench at about 10 tons/acre on 160 new Flame Seedless planting. Covered the trench and planted young vines over the nitrohumus. It's treated and composted human shit from the sewer plants.
I would never use it again. Although high in nitrogen, it's salt content and high metal levels make today's compost look like gold.
Didn't know any better back then. Vineyard still is producing though.
That is completely different than composted humanure. It's made into toxic sludge at the waste treatment plant. Once it enters water, it becomes pollution.
So, yeah, that would be horrible stuff, full of all the chems and byproducts used to 'clean' it.
Like comparing Miracle Grow to Foxfarms.
