Food security is among the most fundamental of national interests and productive farmland is essential for secure grain supply. With the increase of agricultural intensification and the impact of global climate change, the soil in the earth is facing various degradation problems such as compaction, acidification, and salinity. Such soil degradation is usually caused by inadequate or excessive fertilizer input and insufficient litter return to boost soil organic matter, resulting in food insecurity and a need for more sustainable management. Thus, improving soil quality or health is foundational for sustainable crop production, provide greater internal capacity to reduce external input and resistant to environmental changes. As soil is a complex and multicomponent system, the effect of single practices on soil quality are limited and systems engineering by incorporating various innovations and practices to improve soil quality and crop yield is required. Therefore, it is imperative to demand holistic research from multiple disciplines to minimize soil degradation while simultaneously promoting soil health and crop production.
