We tested whether pine-wood-derived biochar can enhance soil \u201csponge function\u201d and reduce erosion in a repeatedly burned pine plantation soil from Central Portugal. In an outdoor box-lysimeter experiment (Oct 2019\u2013Sept 2020; 11 rainfall events; 25% slope), we compared control, with 2% (B2) and 4% (B4) biochar-amended soils on a dystric\/humic (skeletic) Leptosol, all sown with a biodiverse seed mixture. Both biochar treatments reduced runoff (B2 \u221219%; B4 \u221217%) and erosion (B2 \u221267%; B4 \u221249%) and increased vegetation cover (B2 +141%; B4 +113%). Using sediment organic matter, estimated soil organic carbon (SOC) loss declined by 58% under B2 and 13% under B4 versus the control. The stronger performance of 2% indicates an efficiency threshold relevant to post-fire soil conservation and land management.<\/jats:p>","DOI":"10.2139\/ssrn.6465282","type":"posted-content","created":{"date-parts":[[2026,3,24]],"date-time":"2026-03-24T20:43:56Z","timestamp":1774385036000},"source":"Crossref","is-referenced-by-count":0,"title":["Material
