Humic acid (HA) is an environmentally friendly and efficient soil amendment that plays a crucial role in the improving of saline-alkali soils. This study investigated the effects of HA on soil water retention, maize growth characteristics, water use efficiency (WUE), and economic benefits (∆NP) in c...
