3–7 September 2017 • Rothamsted Research • Harpenden (United Kingdom)
Chair: Fanqiao Meng (Chinese Agricultural University, CN)
Soil organic matter (SOM) is essential for soil health, land productivity, climate change and ecosystem function. SOM is greatly affected by social, economic and particularly policy factors. The status of SOM varies by agro-ecological zones, by soil types and by cropping patterns, for instance, a deterioration in some African counties but an improvement in North China Plain. This section welcomes the examinations of national/international policies’ impacts on SOM and how the improvement or maintenance of SOM can be achieved from the perspective of policy. The polices include but not limited to land tenure arrangements, financial subsidies, carbon trading, food production goal, fertilizer usage, crop residues and animal manure management, renewable energy, and national/international action plans. SOM research polices is also an important issue within this section.
