DESCRIPTION:Research Topic: Enhancing Soil Biosolarization: Evaluating the 
 Mechanisms and Application Impact of Eggshell Waste as an Amendment\nAbstr
 act:  ** Lecture will be given in English**\nSoil biosolarization (SBS) i
 s a sustainable approach for managing soil-borne pathogens through the inc
 orporation of organic amendments into solarized soil. Eggshell waste (ESW)
 \, a mineral-rich agricultural byproduct generated in large quantities\, r
 emains underutilized despite its potential value for soil management. In a
 ddition\, the application of mineral-rich waste materials as SBS amendment
 s has received limited attention. This study investigated the use of ESW a
 s a novel SBS amendment and further explored bioaugmentation as a microbia
 l inoculation strategy for enhancing ESW-SBS performance.\nThe impacts of 
 ESW-SBS were evaluated through laboratory simulations and field experiment
 s\, focusing on underlying mechanisms and application effects. ESW amendme
 nt increased soil pH and calcium availability\, while promoting shifts in 
 microbial community composition during SBS. Microbial community analyses f
 urther suggested enrichment of taxa potentially involved in organic matter
  decomposition and biocontrol-related functions\, together with increased 
 microbial activity. Greater bacterial network complexity indicated enhance
 d microbial connectivity during the SBS process. In addition\, volatile or
 ganic compound (VOC) profiling showed increased signal intensity of compou
 nds with potential pathogen-suppressive activity. Residual phytotoxicity r
 emained reversible\, with no inhibition of seed germination and improved p
 lant performance observed under ESW-SBS treatments. Bioaugmentation result
 ed in strain-dependent improvements in ESW-SBS performance.\nOverall\, thi
 s research provides new insights into the mechanisms and application poten
 tial of ESW-amended SBS. The findings support the development of sustainab
 le soil disinfestation strategies that integrate agricultural waste valori
 zation\, microbial community modulation\, and soil management.
