Resumen
Descripción
Black soils cover around 1.03 million square metres in Northeast China and produce between 22.5 and 25 million tonnes of commercial grains annually. However, unlimited exploitation and unsustainable farming practices on these fragile soils through intensive tillage, which has led to depriving the land of soil organic carbon (SOC), as well as excessive removal of organic matter and unregulated use of chemical fertilizers over the past few decades have produced significant land degradation, nutrient imbalance and an annual average loss of 0.3-1.0 cm of the black soil layer. Due to its inherent fertility, recovering black soils is essential to ensure food security in China, and maintaining SOC is crucial to enhance black soils resilience against droughts and extreme temperatures caused by climate change. Jilin Province in Northeast China is one of the most affected, given that great part of the area is rich in black soils. Although the government implemented several regulations, the province is facing several technical challenges to increase SOC and return crop residues to the land. In order to address this situation, this project aimed to develop sustainable and appropriate technical guidelines and policy recommendations to improve black soils management in Northeast China, which would contribute to food security and sustainable production systems.
