Livestock integration into soybean systems improves long-term system stability and profits without compromising crop yields

Abstract Climate models project greater weather variability over the coming decades. High yielding systems that can maintain stable crop yields under variable environmental scenarios are critical to enhance food security. However, the effect of adding a trophic level (i.e. herbivores) on the long-te...
