Problem is they generally only look at one crop at a time, some compare different hydroponic methods, others look at the economics of different systems.
Results are of the swings and roundabouts types.

 

Use of human waste on farms was banned over 100 years ago in the UK due to public health issues. Prevention of TB, Cholera etc, was the reason. Now with heat treatment it may be OK again but I doubt it's use for food crops would be acceptable to the public. I know some councils used to make it available for non edible plants, a school friends father used it on his roses every year. Not sure of the situation nowadays.

 

I have never used this material but it is widely used on cereal land, especially where no livestock manure is available.It is regulated by the Environment Agency and requires special licence for storage. It is required to be incorporated (ploughed) within 24 hours of spreading.Contracts for vegetable crops usually exclude its use, not sure about potatoes. I have reason to believe it is permitted for grow bags but not ,I think in growing media compost.

 

Not manor farm, ages away. Only unusual as hes never done it before, at least not in my 26 years.

Thanks for the info. I assumed the hay was dried with that herbicide, how else were the horses eating it? was it being sprayed on their grass fields or something?

Hot fermentation can degrade drugs and hormones, and potentially some plastics, but heavy metals and really persistent things like pfas, yeah. And it could end up just super accumulating in our food chain, each year the fields get worse and worse.

Solution to this is only to remove the source contamination! Anything to avoid the ultimate apocalypse: the slow building of a giant undegradable stinking pile of s-
