Abstract Nutrient management has led to unprecedented increase in crop production, but with significant carbon (C) trade-off that has close nexus with energy flow. We quantified the impacts of nutrient management on emission of greenhouse gases, net ecosystem C budget (NECB) and energy flow in three cropland ecosystems (rice–wheat, maize–wheat and cotton–wheat). Carbon dioxide ( CO2) and nitrous oxide ( N2O) emissions were significantly (p
