    <title language="eng">Assessing the Impact of Pyrolysis Biochar Derived from Sewage Sludge on Growth Responses and Plant Compatibility across Various Plant Species</title>
    <abstract language="eng">Sewage sludge, a byproduct of municipal wastewater treatment, poses challenges in disposal due to its increasing global production. The pyrolysis process is explored to address this issue, converting sewage sludge into biochar with advantages such as eliminating pathogens, reducing odors, and stabilizing organic carbon. This research underscores the environmental benefits of utilizing biochar as a soil amendment, given its porous structure, carbon and nutrient retention capacity, and potential to enhance plant development and soil quality. By evaluating the impact of pyrolysis biochar from sewage sludge on plant growth and compatibility, the research aims to provide valuable insights for sustainable agricultural practices and waste management strategies.&#13;
Pot trials were conducted in the university greenhouse, incorporating findings from a range of prior studies as a guiding framework. Diverse plant species were selected for experimentation, aiming to assess both plant compatibility and the influence of pyrolyzed biochar. This research investigates the contextual influence of sewage sludge biochar on water-holding capacity (WHC) across different soil types. Contrasting effects were observed, with silty clay loam experiencing decreased WHC and sandy loam exhibiting an increase, highlighting the soil- specific impact of biochar on water retention. Gaseous toxicity and phytotoxicity tests confirmed the absence of harmful gases, challenging previous findings. Plant compatibility tests underscored species-specific responses, emphasizing the need for tailored approaches when utilizing biochar as a soil amendment. Germination tests supported the idea that biochar does not adversely affect seed germination. Root analysis revealed biochar-induced fine root proliferation, suggesting enhanced nutrient availability for plants. In the context of Rhizobium inoculation, common beans in the biochar medium have exhibited smaller dimensions, influenced by the interaction between biochar and Rhizobium inoculation rates. This study provides valuable insights into the multifaceted impacts of sewage sludge biochar in diverse agricultural contexts.</abstract>
