ABSTRACT: In this study, evaluation of two‐superabsorbent effects, Super‐AB‐A‐300 and Super‐AB‐A‐200 in a sandy soil on the water retention capability and saturated hydraulic conductivity ( Ks ) at different water quality and soil temperature were done. The Super‐AB‐A‐200 was less effective in water uptake than Super‐AB‐A‐300. The efficiency of these polymers in water retention was negatively influenced by the water quality and temperature. The efficiency of these polymer treatments in water uptake reduced significantly (P < 0.05) with increasing soil temperature. In the control soil, the Ks stayed nearly constant with increasing soil temperature. As compared to the untreated control, the treated soil demonstrated a significant (P < 0.05) linear increase of Ks with increasing soil temperature. In the control soil, the water holding properties curve did not change with increasing soil temperature.
