Research Project: DEVELOPING SUSTAINABLE 'IN ROW' MANAGEMENT PRACTICES FOR IMPROVING WEED MANAGEMENT AND SOIL NITROGEN RETENTION

Location: Crops Pathology and Genetics Research

Project Number: 5306-21220-005-04
Project Type: Trust

Start Date: Apr 14, 2010
End Date: Apr 15, 2013

Objective:
Develop alternative 'in row' weed management practices that both provide effective weed management, do not negatively impact grapevine growth and juice, and improve soil nitrogen (N) retention by minimizing inorganic N leaching and nitrous oxide (N2O) emissions.

Approach:
Frequent monitoring of weed establishment, bimonthly N2O emissions, and vine nutrient status. Specific periods of dynamic N transformations such as fertigation will be monitored to accomplish objectives.
