dc.description.abstract Future changes in crop composition could contribute to more sustainable food systems, optimizing land and fertilizer use. Changes in crop composition strongly affect how much soil nutrients need to be withdrawn per unit of food output. The paper explores three aspects of major global crops and to what extent crop choice offers the potential to increase food outputs at a faster rate than soil nutrient withdrawals and fertilizer use on the same available land. While soil nutrient needs shift in response to basic biological attributes of crops; fertilizer additions are more dependent on the economic context of crop production. en
