The growing human population will drive global demand for food and feed, which impacts major grains production (Tilman, 2011). A substantial increase in grain production of as much of 70 is needed, coupled with ensuring that the agriculture environmental footprint created is kept as low as possible. Given the limited resources and availability of uncultivated land, it is projected that grain production needs to come mostly from existing farmland (Gan, 2014).The rising greenhouse gas emissions globally have elevated concerns of the impact on the planet and effects on climate change. The United Nations have established the 17 global Sustainable Development Goals which aim to restore and promote social, economic and environmental sustainability. Goal 13: "Take urgent action to combat climate change and its impacts" emphasises that actions need to be integrated into national policy, strategies and planning. Therefore, identifying measures to reduce on-farm emissions is a contribution to this goal, in reducing carbon emissions. Sixty-five percent of Agricultural energy emissions in 2050 is expected to come from on farm energy use (World Resources Institute, 2020).
