Research Progress of Agricultural Soil Health Evaluation System

Soil health plays a vital role in global food security and ecological security. The decline of soil quality caused by human activities and other factors is widespread. How to improve soil health has been one of the most important hotspots and frontier issues on a global scale. The study systematically introduces the soil health evaluation system and its application status in domestic and foreign, summarizes the application of the existing soil health evaluation systems in agricultural management practice, and examines the development trend of the soil health evaluation system in China. The existing soil health assessment system needs to add some new indicators and new technologies, establish China′s agricultural soil health network, use big data to understand the relationship between agricultural management practice and soil health, and develop an agricultural soil health assessment system which is suitable for China′s climate environment and soil conditions. Finally, to provide theoretical support for improving China′s agricultural soil health and realizing the goal of sustainable development, the solutions to maintain China′s agricultural soil health are proposed based on the establishment of a soil health evaluation system and the cognition of social level on agricultural soil health.
