Research Project: REDUCING OUR FOOTPRINT: MINIMIZING GREENHOUSE GAS EMISSIONS AND NITROGEN LEACHING IN VINEYARDS, AND ENHANCING LANDSCAPE CARBON STOCKS Project Number: 5306-21220-005-02
Project Type: Reimbursable

Start Date: Oct 01, 2009
End Date: Jun 30, 2012

Objective:
Characterize soil variability through a landscape-targeted approach emphasizing major soil landscape relationships to stratify the two winegrowing regions into geographic management templates; link greenhouse gas (GHG) emissions and vineyard nitrogen retention to these templates; Extend research findings.

Approach:
Characteriztion of GHGs in response to vineyard floor management; Assessment of tradeoffs for weed pressure and N loss through leaching; Performance of life cycle analyses to assess whole vineyard GHG footprints; Repackage digital soil survey into geographical management templates that depict specific soil properties (and microclimates) that govern C and N dynamics and their respective affinities for C and N within the soil landscape; Develop a publication using a grower-friendly format, and include practical methods for measuring carbon (C) sequestration and reducing GHG emissions and nitrate leaching.
