The end of soya, maybe?

Buford T. Justice XIX

Farmyard slurry has been transformed from a waste product needing storage into a way for farmers to grow animal feed thanks to pioneering research being carried out by UCC scientists.

So, basically, they use the watery fraction of slurry to grow duckweed on and this can be harvested and fed to cattle of sold for use in cattle rations. It seems to need something like reed beds to grow on and there's a demonstration unit going to be set up to demonstrate the conditions needed.

Could be a game changer for feeding animals.

Hoe will you harvest it, a tractor hovercraft sound like more cost. If slurry is removed as a fertlizer on silage ground and arable crops what will replace it. Artificial fertlizer. Solution to slurry for Ireland anyway is the fixing of the N component to a niece a higher N utilisation

Replace duckweed with spirulina and this technology has been out these past thirty years.
Actually replace duckweed with spirulina and the question is why are you feeding that food source to cattle and not humans?
It can also be used as a fertilizer greater than the sum of the nutrients used to feed it.

About 35% protein is a behind soya and it is very wet.
Other than that it looks promising
