Short summary
The main problem of acid sulfate soil is that it has a low soil pH and contains a high amount of aluminum (Al). There have been several approaches to improve this soil. In this study, the application of calcium silicate was found to be a suitable soil ameliorant as it alleviated Al toxicity below the critical level for rice production, as well as also providing a sufficient amount of silicon (Si) and calcium (Ca), which are also needed for rice growth.
