Over recent years the concept of `knowledge' in the singular has been increasingly challengedby ideas of differentiated, contextualized `knowledges'. In this paper we propose the concept of`knowledge-cultures' as a way of exploring the fluidity of diverse forms of knowledge and the rules,norms, and values that enable or constrain their production. Elaborating on Shotter's idea of knowl-edge-from-within, we argue that knowledge-cultures are social achievements that equip those whoembody them with a relational ^ responsive kind of understanding of events and surroundings built onmultiple knowledge-forms. To explore this contextual nature of knowledge-culture construction andillustrate our arguments, we draw on detailed empirical research of farmers' experiences with theprecision-farming technique of yield mapping in the English counties of Lincolnshire and Suffolk.
