Session: Symposium--the Agronomy of Precision Water Management (ASA, CSSA and SSSA International Annual Meetings)

42 Symposium--the Agronomy of Precision Water Management

Oral Session

ASA Section: Agronomic Production Systems

Sponsored by DuPont Pioneer, Monsanto Company, Valmont Industries, and Lindsay Corporation. Water continues to be the dominant factor affecting crop production. Both water excesses and deficiencies exist in spatial and temporal dimensions. Precision water management taking into account variations in time and space offers tremendous opportunity for improved management efficiencies and increased crop production. This symposium will address the agronomic factors that should be considered for precision water management, explore approaches for doing so, and highlight with case study examples.
