Biochar is a promising amendment for degraded soils with low fertility and high levels of heavy metals contamination, since it can reduce Cd2+ levels in vegetables. However, these reductions depend on the nature of the soil and biochar properties. This pot experiment in greenhouse conditions evaluated the effect of biochars amendments under Cd stress conditions on lettuce (Lactuca sativa L. var. crispa L.) plants grown in four soils: Ferralsol (FS), Andosol (AS), Umbrisol (US) and Technosol (TS). Six treatments were compared: Biochars doses at 3, 6, 9 and 12 t ha-1, conventional fertilization (NPK) and control absolute. Biochars were obtained by slow pyrolysis from five agricultural residues: Palm empty fruit bunches (PEFBB), palm kernel (PKB), wood waste (WWB), coffee pulp (CPB) and rose stems (RSB). The CPB amendment resulted in a fresh weight plant increase of 238% to 323% in 3 to 12 t ha-1 comparing with control treatment, while WWB induced a fresh weight decrease of 90.85%. The PKB amendment presented a 20% additional fresh weight in comparison to PEFBB in Ferralsol. These results indicate that biochar positively contributes to the water status. Application of RSB at 12 t ha-1 resulted in a decrease of 50.61% in Cd concentration and a decrease of 37.4% in Cd concentration in CPB at a 12 t ha-1, both results representing promising alternatives to remediate contaminated soils. The AS+CPB and US+RSB assays showed a significant negative correlation of leaf Cd concentration when increasing biochar doses were used indicating the mitigation of the phytotoxic effect of Cd in plants.http://purl.org/coar/resource_type/c_6501Rivera, JulioReyes, JhonCuervo, JairoMartínez-Cordón, MaríaZamudio, AdrianaTHUMBNAILArtículo de investigación indexado con enlace de consulta de manera referencial (2).pdf.jpgArtículo de investigación indexado con enlace de consulta de manera referencial (2).pdf.jpgIM Thumbnailimage/jpeg8825https://expeditiorepositorio.utadeo.edu.co/bitstream/20.500.12010/32115/4/Art%c3%adculo%20de%20investigaci%c3%b3n%20indexado%20con%20enlace%20de%20consulta%20de%20manera%20referencial%20%282%29.pdf.jpg8f22f8006469106381df5badf16cfc1bMD54open access0718-5839-chiljar-82-02-244.pdf.jpg0718-5839-chiljar-82-02-244.pdf.jpgIM Thumbnailimage/jpeg23978https://expeditiorepositorio.utadeo.edu.co/bitstream/20.500.12010/32115/5/0718-5839-chiljar-82-02-244.pdf.jpgd4064335f5fcf9656477f24086b75ed6MD55open accessORIGINALArtículo de investigación indexado con enlace de consulta de manera referencial (2).pdfArtículo de investigación indexado con enlace de consulta de manera referencial (2).pdfapplication/pdf48864https://expeditiorepositorio.utadeo.edu.co/bitstream/20.500.12010/32115/1/Art%c3%adculo%20de%20investigaci%c3%b3n%20indexado%20con%20enlace%20de%20consulta%20de%20manera%20referencial%20%282%29.pdfad3fe84c3dde038025c42938f551e755MD51open access0718-5839-chiljar-82-02-244.pdf0718-5839-chiljar-82-02-244.pdfapplication/pdf2131671https://expeditiorepositorio.utadeo.edu.co/bitstream/20.500.12010/32115/3/0718-5839-chiljar-82-02-244.pdf704d14e9c39f9566210d4884b5b14d70MD53embargoed access|||2223-10-06LICENSElicense.txtlicense.txttext/plain;
