Temporal change of pore volume (mean of planted and unplanted columns) at different pore classes according to SSSA (2013) between initial and final drainage experiment in the upper (0–30 cm) and lower (30–60 cm) layers of the soil columns

	Volume change cm 3 cm −3
	Upper layer	Lower layer
Micropores1 (r < 2.5 μm)	0.0304	0.0274
Micropores2 (2.5≤ r < 15 μm)	−0.0146	−0.0451
Mesopores (15≤ r < 37.5 μm)	−0.0136	−0.0230
Macropores1 (37.5≤ r < 500 μm)	−0.0167	−0.0269
Macropores2 (r ≥ 500 μm)	0.0011	0.0049
