The results showed a significant positive correlation (r = 0.287, 0.01) between infiltration rate and organic matter, whereas other parameters showed no significant correlation (Table 2). Several studies also found a significant positive relation between infiltration rate and organic matter (Osuji et al. 2010; Haghnazari et al. 2015; Wang et al. 2018). Soil organic matter was considered to be the chief component for determining soil quality (Tiwari et al. 2006), hence the soils with high infiltration rates are of good quality index due to high organic content. During the dry season, soil moisture decreases resulting in an increase in absorption capacity (sorptivity) of soil and cumulative infiltration (Yasin & Ghazal 2021). However, in the present study, there seems no apparent impact of soil moisture content on the basic infiltration.
