I fully expect you to pay no attention to the content and instead throw shade on the sources, but here’s your opportunity to show good faith.

This quote is directly from the DPRK in 2014:

It is necessary to apply large quantities of manure to paddy and non-paddy fields to fertilize land and increase unit-area yield sustainably. Manure production is just increased grain production. The agricultural sector should channel efforts into manure production to turn out more than 20-30 tons of it per hectare of paddy and non-paddy fields. Cooperative farms should find out and use all sources of manure such as domestic animal excrement, night soil, compost and ditch-bed soil.
