WebMar 1, 2015 · Quantifying soil structure, in a sense is characterizing the soil physical condition, or relationships of an integrated soil solid–liquid–gas system. Quantitative relationships of soil three phases can be characterized in various ways but fundamentally must begin by considering their mass or volume ratios ( Kay, 1990).
