Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate-smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented and modeled two climate-smart practices (diverse cover crops and innovative manure management). Our results show the need to optimize addition amounts to ensure sustained yield with lowered GHG emissions. Moreover, we completed a successful collaboration that led to farmer adoption of recommended practices.
