Making compost from dairy manure solids 

Cool. I don't understand why anyone uses synthetic fertilizers.

Can u send or suggest a document or website for studying more about composting from manure.

This is good stuff. Have been suffer with disposal of dung. What is the name of the implement on the tractor.

How does a person order loads of that?

Not sure how a dairy farmer can compost most of his cow manure, sell the compost then use mostly commercial fertilizer for his cropland and be selected as "wisconsin sustainable dairy farm of the year". Seems pretty sketchy to me.

What ratio of Straw and manure is?
