The average coarse mesoporosity of GB (0.0040 m3 m−3) and AB
(0.0039 m3 m−3) treatments were almost the same for the first five
scan depths. The AB and GB treatments had 32 and 19 times higher
coarse mesoporosity for the 10- to 20-cm depth than the RC
treatment. For the third depth zone, RC and GB had the same porosity
values (0.0032 and 0.0033 m3 m−3) while AB had (0.0040 m3 m−3) a
higher value. The average coarse mesoporosity of 30- to 40- and 40- to
50-cm depth zones was higher for the AB treatment (0.0048 and
0.0022 m3 m−3) than the GB (0.0028 and 0.0012 m3 m−3) and RC
(0.0019 and 0.0005 m3 m−3) treatments.
