“…Although there is vegetation in riparian areas where the groundwater table is deep and capillary rise is insufficient, they can be susceptible to desiccation. A method has been proposed using clinoptilolite zeolite's (CZ) hydraulic properties as a wicking material to grow plants [12][13][14]. However, the alleviation of water stress in riparian plants using zeolite as a wicking material to grow plants is not well understood.…”

“…It is composed primarily of aluminosilicates in a three-dimensional crystal lattice with loosely bound cations and can hydrate and dehydrate without altering its crystal structure [22]. Dung et al [13] showed that CZ could be used as a wicking material to raise water to 1.5 m and as an amendment to sandy soils to improve their water retention properties. Piñon-Villarreal et al [14] also tested the capillary rise of CZ and riparian soils in a field experiment and compared it with a simulation model using Hydrus-1D.…”

Plants in riparian areas are well known for their beneficial functions such as providing biodiverse habitats, maintaining water quality, and stabilizing streambanks. However, riparian plants are declining in semi-arid environments due to long-term drought, a decline in groundwater table, and an increase in soil salinity. A new technique using clinoptilolite zeolite (CZ) as a wicking material with minimum artificial irrigation to grow desert willow [Chilopsis linearis (Cav.) Sweet] under field conditions is introduced; desert willow is native to riparian regions of the southwestern United States. For this study’s experiment, desert willow seedlings were planted in boreholes filled with clinoptilolite zeolite (CZ) as a substrate and in situ riparian sandy loam soil (RS) as a control. The boreholes extended to the groundwater table at two distinctive depths, shallow (avg. depth = 1.21 m) and deep (avg. depth = 2.14 m). The plants’ viability was then assessed by measuring their midday water potential (Ψmd) as an indicator of water stress. There was no significant difference in Ψmd (p > 0.05) between the plants grown in CZ and RS (mean Ψmd = −0.91 vs. −0.81 MPa) where the groundwater was shallow and a significant difference (mean Ψmd = −0.75 vs. −2.03 MPa) where the groundwater was deep. The proposed method is promising as an alternative method for growing desert willow or other plants for riparian rehabilitation with no artificial irrigation. However, its effectiveness depends on groundwater being accessible at the base of the boreholes used for planting.
