“…However, it can be highlighted that plant organs in soils with biochar had 11.6% more HM retention. These results coincide with those reported in the literature, in which the addition of biochar to the soil can modify soil properties such as pH and EC. ,, …”

“…These results coincide with those reported in the literature, in which the addition of biochar to the soil can modify soil properties such as pH and EC. 42,43,64 The concentration of HM retained in plant organs by the HM group was also compared. A marginally significant difference was found in the effect of the HM type on the concentration of HM in plant organs.…”

“…Biochar also helps to reduce greenhouse gas emissions from agricultural residues. This is because it has a high recalcitrant carbon content, which contributes to increased soil carbon sequestration. ,, In Colombia, more than 71 million tons/year of crop residues are produced, among which sugar cane and coffee stand out, of which only 17% is used . The waste produced in the coffee industry is 5 million tons/year between pulp, husks, and stalks, , while the waste generated in the sugar cane industry in the case of leaves is estimated at 9 million tons/year .…”

Soil contamination with heavy metals (HM) poses significant challenges to food security and public health, requiring the exploration of effective remediation strategies. This study aims to evaluate the remediation process of soils contaminated with Cd, Cr, and Pb using Lolium perenne assisted by four types of biochar: (i) activated coffee husk biochar (BAC), (ii) nonactivated biochar coffee husk (BSAC), (iii) activated sugar cane leaf biochar (BAA), and (iv) nonactivated biochar sugar cane leaf (BSAA). Biochar, loaded with phosphorus (P), was applied to soils contaminated with Cd, Cr, and Pb. L. perenne seedlings, averaging 2 cm in height, were planted. The bioavailability of P and heavy metals (HM) was monitored every 15 days until day 45, when the seedlings reached an average height of 25 cm. At day 45, plant harvesting was conducted and stems and roots were separated to determine metal concentrations in both plant parts and the soil. The study shows that the combined application of biochar and L. perenne positively influences the physicochemical properties of the soil, resulting in an elevation of pH and electrical conductivity (EC). The utilization of biochar contributes to an 11.6% enhancement in the retention of HM in plant organs. The achieved bioavailability of heavy metals in the soil was maintained at levels of less than 1 mg/kg. Notably, Pb exhibited a higher metal retention in plants, whereas Cd concentrations were comparatively lower. These findings indicate an increase in metal immobilization efficiencies when phytoremediation is assisted with P-loaded biochar. This comprehensive assessment highlights the potential of biochar-assisted phytoremediation as a promising approach for mitigating heavy metal contamination in soils.

“…In addition to the previously discussed points, it has been reported that pyrolysis contributes added value to soil properties. For instance, a review on biochar application to Mediterranean soils -known to be vulnerable to water scarcity and loss of organic matter-concluded that biochar can effectively improve soil water content under limited water conditions during summer and drought periods due to its potential to store carbon [ 139 ]. Water holding capacity was reported to improve in soils amended with biochar produced at high temperatures of 800 °C compared with biochar produced at lower temperatures [ 140 , 141 ].…”
