DESCRIPTION:Enhancing Soil Biosolarization: Evaluating the Mechanisms and A
 pplication Impact of Eggshell Waste as an Amendment\nAbstract:  ** Lectur
 e will be given in English**\nSoil biosolarization (SBS) is a sustainable 
 approach for managing soil-borne pathogens through the incorporation of or
 ganic amendments into solarized soil. Eggshell waste (ESW)\, a mineral-ric
 h agricultural byproduct generated in large quantities\, remains underutil
 ized despite its potential value for soil management. In addition\, the ap
 plication of mineral-rich waste materials as SBS amendments has received l
 imited attention. This study investigated the use of ESW as a novel SBS am
 endment and further explored bioaugmentation as a microbial inoculation st
 rategy for enhancing ESW-SBS performance.\nThe impacts of ESW-SBS were eva
 luated through laboratory simulations and field experiments\, focusing on 
 underlying mechanisms and application effects. ESW amendment increased soi
 l pH and calcium availability\, while promoting shifts in microbial commun
 ity composition during SBS. Microbial community analyses further suggested
  enrichment of taxa potentially involved in organic matter decomposition a
 nd biocontrol-related functions\, together with increased microbial activi
 ty. Greater bacterial network complexity indicated enhanced microbial conn
 ectivity during the SBS process. In addition\, volatile organic compound (
 VOC) profiling showed increased signal intensity of compounds with potenti
 al pathogen-suppressive activity. Residual phytotoxicity remained reversib
 le\, with no inhibition of seed germination and improved plant performance
  observed under ESW-SBS treatments. Bioaugmentation resulted in strain-dep
 endent improvements in ESW-SBS performance.\nOverall\, this research provi
 des new insights into the mechanisms and application potential of ESW-amen
 ded SBS. The findings support the development of sustainable soil disinfes
 tation strategies that integrate agricultural waste valorization\, microbi
 al community modulation\, and soil management.
