Fig. 2. Minimum equivalent pore radius, C₀ (Eq. [3], dark points), and representative mean pore radius for two consecutive soil water tensions, , (Eq. [6], white points-) estimated under conventional tillage (CT), reduced tillage (RT), and no-tillage (NT). Macropores are defined as those pores that drain at > –4 cm (C₀ > 0.375 mm) and mesopores as those pores draining at between –4 and –14 cm (0.375 > C₀ > 0.107 mm). Asterisks indicate significant difference between C₀ and (P < 0.05, t-test).
