Implication

Randomized trial demonstrates enhanced yield and quality of Amorphophallus konjac with biochar and LREE, implying improved soil health.

Key Points

This study aims to investigate the effects of biochar and light rare earth elements on the productivity of Amorphophallus konjac under degraded soil conditions.
3 × 3 factorial experiment involving 1–3% biochar and LREE-based composite with control
Soil chemical profiling, metagenomic analysis, and physiological assessments conducted
Evaluation of corm yield, KGM content, and rhizosphere responses
Corm yield increased by 21.6% and KGM content by 26.2% with 3% biochar and 2% LREE interaction
Biochar × LREE interactions significantly influenced soil pH and inorganic nitrogen stabilization, contributing to NH4+-N levels
Metagenomic analysis showed shifts in microbial communities, enriching specific taxa and upregulating carbon and nitrogen cycling genes
