Interpretive Summary:

Technical Abstract: Modern crop production requires large inputs of energy and these inputs represent a substantial cost. Management practices such as crop rotation and choice of tillage practice influence the energy balance for a production system. Legumes support bacteria that are capable of fixing nitrogen (N). This fixed N not only meets the crop needs but a portion is also available for subsequent crops thereby reducing the need for inorganic N fertilizer. Primary tillage practices vary in energy input requirements with no-tillage requiring %15 less energy than moldboard plow tillage (Rathke, 2007). Producers can utilize crop rotations that include a legume and reduced tillage intensity to improve the energy efficiency of their production systems.
