Excerpt:
Scientists at the University of California at Berkeley are using
ground penetrating radar (GPR), a tool better known for its
military uses, to help winemakers create tastier, more uniform
wines. "GPR is an electromagnetic signal that travels in the ground.
What we do is try to understand how fast that signal travels
and that tells us a lot about the moisture content of the soil,"
said Susan Hubbard, a hydrogeophysicist at University of California,
Berkeley, and staff scientist at Lawrence Berkeley National
Laboratory. Understanding soil moisture is a critical part of the art and science
of winemaking. Cabernet Sauvignon and other red wine grapes
prefer drier soil. Chardonnay and other white wine grapes do better
in moist soil.Reggie Bautista More On Site Maru
