EnglishThis field was established in 2016 to systematically monitor the dynamic processes of solid, liquid, and gaseous forms of water, carbon, and nitrogen and reveal their interaction mechanisms; to build an optimal agroecosystem with typical crops and planting methods, standard crop varieties, optimal water and fertilizer management methods, and no obvious disaster in the North China Plain; to build a new set of sample plots for studying the critical zone. A new set of sample plots for studying soil and water processes in the critical zone will be established to form a stable long-term monitoring system for soil and water processes in the critical zone. The sample plots will provide reliable long-term observation data for the improvement of soil fertility and efficient management and regulation of nutrient and water in North China, and provide data, theoretical and technical basis for research and decision making on food security, ecological security and environmental security. At the same time, it provides a platform that can be referred to for the research of national stations of farmland ecosystem, especially the networking of stations of northern farmland ecosystem.
