Correction: Environmental materials: CO₂-adsorbing clays for enhancing soil fertility and agricultural sustainability (Materials Advances (2025) DOI: 10.1039/D4MA01246A)

The authors regret that affiliation ‘‘a’’ was provided incorrectly in the original manuscript. The corrected affiliation is as shown herein. Furthermore, the authors regret two further errors within the manuscript. The equations displayed at the end of Section 4.7 were displayed incorrectly and should be as follows: Si–OH (kaolinite) + RNH₂ (amine) - Si–O^→ N⁺ H₃R CO₂ + 2RNH₂ - RNHCOO^→ + RNH₃ ⁺ Finally, the caption to Fig. 8 contained an error. The corrected figure caption is as follows; Fig. 8 Digital photos of samples used in the current study: (a) roller mixer, (b) sand, PK, CKP-0, CKP-30, and CKP-50, after mixing with sand coded as S-PK, S-CKP-0, S-30, and S-CKP-50, (c) hydroponic apparatus use (open and closed), (d) thermometer for temperature measurement and (e) digital lux meter used to measure light intensity inside the hypophonic apparatus. The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
