Abstract:
Using advanced technologies such as electromagnetic induction (EMI), geographic positioning systems (GPS), and geographic information systems (GIS), in concert with geomorphic site descriptions and soil profile analyses, a soil scientist can: 1) assist the viticulturist in choosing an optimal site, 2) recommend cultural practices to modify an existing site, and 3) provide guidelines to avoid site development altogether.
Cultural methods in a udic soil moisture regime include vertical tillage (“ripping”), placement of a subsoil drainage tile system (“tiling”), installation of wind machines, bioaugmentation, cover cropping, and intensive canopy management.
Geomorphic site descriptions include physiographic, geomorphic, and land surface morphometric descriptors. These data can be valuable to assess parameters such as surface air drainage, disease pressure, and winter injury, all of which affect grape quality and vineyard health.
By using EMI to map a solum, the soil scientist can determine optimal placement of soil profile analyses in order to provide various pedon descriptions within a polypedon.
