196 Symposium--Quantitative Assessment of Management Impacts on Soil-Plant-Water Relations

Oral Session
ASA Section: Climatology & Modeling
This session addresses identifying management (M) factors of the G x E x M interaction to maintain/enhance crop water productivity and the quantitative measures for understanding soil-plant-water relations in achieving maximum crop productivity.  The level and timing of abiotic factors, control of biotic factors, and methods and timing of crop establishment or maturity, but not limited to, the choice of adaptive G will be emphasized and quantified. 

Approved for 3.5 SW CEUs.
