RETRACTION: Ibrahim, A. & Horton, R. (2021). Biochar and compost amendment impacts on soil water and pore size distribution of a loamy sand soil. Soil Sci Soc Am J., 85, 1021–1036. https://doi.org/10.1002/saj2.20242

The above article, published online on 16 March 2021 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal's Editor, William Horwath, the Soil Science Society of America's Editor-in-Chief, Craig Rasmussen, the Soil Science Society of America, and Wiley Periodicals LLC.

The retraction has been agreed following concerns raised from the corresponding author of (Al-Omran et al., 2021), who claimed that he was omitted as an author and was unaware of the article's submission as he pursued the publication of (Al-Omran et al., 2021) in another journal. An investigation by the journal, society, and Wiley observed that (Al-Omran et al., 2021) is based on the same research as this article, with evidence of significant overlap. Therefore, these parties consider this a duplicate publication.

Additionally, further investigation by the author's institution concluded that the article does not disclose the university's funding, nor does it appropriately acknowledge the omitted author. As such, the institution formally requested that the article be retracted.

Corresponding Author A. Ibrahim disagreed with the retraction. Co-author R. Horton collaborated during the investigation and agreed to the retraction.
