20.500.12556/RUL-184494 Environmental applications of agricultural waste-derived biochars for soil improvement and lead adsorption Okoljska uporaba biooglja, pridobljenega iz kmetijskih odpadkov, za izboljšanje tal in adsorpcijo svinca Biochar, a carbon-rich material produced by the pyrolysis of organic waste, has emerged as a low cost and sustainable material for several environmental applications including the enhancement of soil fertility and adsorption of heavy metals. This study evaluated and compared the potential of four plant-based biochars (wheat straw, pine straw, corn cob and parthenium biochars) for environmental applications by analyzing their physicochemical properties. The results showed that of all the analyzed biochars, parthenium biochar was found to be most effective in enhancing soil fertility as it contained the highest total organic carbon (79.50 %) and N contents (2.50 %). Moreover, the concentration of toxic heavy metals was found below safe limits in all the biochars studied in this research which favors their suitability for environmental applications. On the other hand, adsorption studies revealed that the corn cob biochar exhibited the highest lead removal efficiency (98 %) at an adsorbent dose of 2 g l1. Based on these findings, it is concluded that the agricultural waste-derived biochars can be used as sustainable and effective materials for environmental management, including soil quality enhancement and heavy metal remediation. agricultural waste biochar soil fertility enhancement environmental remediation lead adsorption sustainable soil management waste valorization biooglje iz kmetijskih odpadkov povečanje rodovitnosti tal okoljska sanacija adsorpcija svinca trajnostno ravnanje s tlemi valorizacija odpadkov true false true Angleški jezik Slovenski jezik Članek v reviji 2026-07-08 13:10:59 2026-07-08 13:11:03 2026-07-09 04:14:25 0000-00-00 00:00:00 2026 0 0 10 str. no. 2 Vol. 122 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63 1854-1941 10.14720/aas.2026.122.2.25944 284066819 BATOOL+et+al.+(P).pdf BATOOL+et+al.+(P).pdf 1 B449879B8FA6292E8E0D0A8F6A07B922 6564eeb0b07c006f03b22146601d9d6ded9852d85883f052aa31b56001ec0fe4 ae52b3f5-7abd-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=237355 https://journals.uni-lj.si/aas/article/view/25944 1 99382200-7abd-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=237354 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
