Evaluating the effectiveness of solarization for enhancing phosphorus availability in acid sulfate soil: a pilot study in plain of reed, Vietnam

Year: 2025

Type: article

Abstract: This study evaluated effectiveness of solarization on the available P in acid-sulfate soil (ASS). The pilot study was conducted in a yam-growing area in Long An, an active ASS in the Plain of Reed. The experiment was conducted for 45 days, with two types of cover sheets and two types of irrigation regimes. The available P in the solarization experiments (from 15.87 to 90.46 mg/kg DW) was higher than the control (from 23.94 to 47.18 mg/kg DW). The highest available P was obtained in treatment (Clear plastic, irrigated) (81.96 ± 6.26 mg/kg DW), followed by treatment (Black plastic, no irrigation) (64.78 ± 14.74 mg/kg DW). The soil pH of the treatment plots (mean of 3.91) was similar to the pH of the controls (mean of 3.83). There was an interaction between the two treatments during the incubation period, which affected the concentration of available P in ASS.
