Willcox AVA Soil
Soils derive from the geology of an area and their physical and chemical properties help determine characteristics like water infiltration, storage, and draining, erodibility, and acidity or alkalinity. These components can inform winegrape growers on site and variety suitability, vineyard design and infrastructure, vine growth and yield, as well as potential wine styles for which their fruit may be best.
