"Soil is like any other variable... such as pest populations or vine canopy parameters, yield, crop uniformity and distribution, light exposure or shoot density. To manage them well and be able to reliably predict and control the quantity and quality of the crop, we need to be able to accurately assess them."
- Dr. Cliff Ohmart from 2009 Wines and Vines article on STI
