Combined biochar and water-retaining agent application increased soil water retention capacity and maize seedling drought resistance in Fluvisols.

Global climate change has accelerated the occurrence of agricultural drought events, which threaten food security. Therefore, improvements in the soil water retention capacity (WRC) and crop drought resistance are crucial for promoting the sustainability of the agricultural environment. In this study, we explored the effects of applying biochar and water-retaining agent (WRA) on soil WRC and crop drought resistance in a Fluvisols, along with their potential mechanisms.

Remediation of arsenic-contaminated paddy soil: Effects of elemental sulfur and gypsum fertilizer application.

Heavy metal(loid) contamination represents an immense challenge in sustainable agriculture. Arsenic, in particular, poses a great risk to the quality of agricultural products (e.g.
