Implication

Integrated pot and field experiments confirm biochar boosts root growth and photosynthesis in maize, suggesting improved agricultural practices in arid regions.

Key Points

Biochar application at 7.5 t ha−1 increased soil-saturated water content by 11.4%, enhancing water retention in arid soils.
Root weight density in maize grew by 21.0% with 7.5 t ha−1 biochar, indicating improved growth conditions.
Net photosynthesis and stomatal conductance under drought were reduced by 24.5% and 21.4% with biochar, suggesting better drought resilience.
The study highlights a sustainable strategy for agriculture in arid regions by optimizing soil properties and crop response.
