sorry for being sloppy, James. I mean the innovations of agricultural improvement movement in the 17th and 18th century (i.e. early capitalist agriculture), most of which were simply appropriated from the surrounding farmers by doing a careful study of best practices. They were also very big on "manurance" so much so that it became a metaphor for all kinds of culture, not just agriculture.
