Session: Symposium--Partnering to Understand Complexity: Biogeochemical Cycles in Agricultural Systems (ASA, CSSA and SSSA International Annual Meetings (2015))

200 Symposium--Partnering to Understand Complexity: Biogeochemical Cycles in Agricultural Systems

Oral Session

Special Sessions

The increasing food demand and the emerging environmental challenges, including nutrient loads in ground and surface water and greenhouse gas emissions, call for fine tuning of nutrient management in agricultural systems. Grazing and manure additions add to the complexity of biogeochemical cycles in agricultural systems, by impacting soil, water, air and biota processes and relationships. This special session is focused on the partnering for solutions across societies to study the complexity of nutrient cycling in agricultural systems by fostering of interdisciplinary research approaches. The session aims to bring 3-4 presentations per project that will showcase how the interdisciplinary approach contributes to the synergy in science and the results across disciplines.

Approved for 3.5 PD CEUs.
