Session 4: Nutrients for Food
Time slot:
Nov 27, 2020 — 08:00-10:00
(UTC Change)
Nitrogen (N) and Potassium (K), Phosphorus (P) are the essential nutrients in plant growth. Commercial food production is largely dependent on fertilizers, and feeding the world’s burgeoning population will require a plentiful supply of nutrients in the years to come. The non-substitutable property of nutrients in agriculture production process and for sustaining most of life on the earth makes securing stable supply chains of agricultural nutrients and their proper managements particularly pressing issues. We will discuss these issues in this session with a line of four speakers covering local and global supply and demand, and circular economy aspects.
