Agriculture green development (AGD) is the future for modern agriculture, and soil health is the cornerstone of AGD. This article summarized the connotation, research progress and trend of soil health in domestic and overseas. By summarizing the main management strategies for healthy soil cultivation, this paper puts forward novel ideas and approaches for promoting soil health, and discusses the challenges and opportunities for soil health engineering. The cores for the promotion of healthy soils are: eliminating the limiting factors of soils; increasing the content of soil organic carbon and nutrient use efficiency; exploiting the biological potentials; promoting synergistic interactions between above-ground and below-ground. The aim of soil health engineering is to synergize the production and other ecosystem services delivered by soils by optimizing the internal regulatory processes whilst minimizing the external inputs. The cultivation of healthy soil needs holistic engineering, which requires comprehensive integration of whole industry chain in the nexus of external input, crop production, products-processing, and waste recycling. Meanwhile, cross-disciplinary innovation, government-farmer-research-extension institute collaboration, and policy support and incentive systems are crucial for realizing soil health towards AGD.
