Abstract Large amount of wastes are burnt or left to decompose on site at landfills where they cause air pollution and nutrient leaching groundwater. Waste management strategies that return these food agricultural soils recover the carbon nutrients would otherwise have been lost, enrich improve crop productivity. The incorporation liming materials can neutralize protons released, hence reducing soil acidity its adverse impacts environment, security, human health. Biochar derived from organic residues is becoming a source input provides multifunctional values. be alkaline in nature, with level alkalinity dependent upon feedstock processing conditions. This study conducted characterization biochar pyrolysis process eggplant Acacia nilotica bark temperatures 300 °C 600 °C. An analysis was kinds determine their pH, phosphorus (P), as well other elemental composition. proximate by ASTM standard 1762-84, while surface morphological features were measured using scanning electron microscope. exhibited greater yield higher fixed possessing lower content ash volatile components compared eggplant. exhibits ability acacia bark-derived biochar. calcium carbonate equivalent, potassium (K), (P) levels biochars increased temperature increased. results suggest could beneficial resource for storing soil, addressing enhancing availability, particularly acidic soils.

Soil contamination with cadmium (Cd) and chromium (Cr) pose serious threats to food safety ecosystem stability. In current study, pristine biochar (BC) iron-modified (Fe-BC) were prepared, the potential of BC Fe-BC reduce bioavailability Cd Cr in soil, their uptake, toxicity rapeseed (Brassica napus L) mechanisms involved examined. a pot experiment varying levels applied Cr-contaminated soil. The results indicated that soil supplementation highest level (2 %) incremented dry weights roots, shoots, seeds by 65 %, 33 149 respectively. Additionally, treated plants showed increase photosynthesis, transpiration, stomatal conductance, intercellular CO2 emissions, chlorophyll contents 43.2 39.5 33.5, 36.9 % 28 Plants amplified superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) activities. regarding saturated unsaturated fatty acid treatment exhibited greatest linolenic acid, oleic erucic linoleic contents, increasing these acids 21 6.5 53 14.5 Moreover, depicted increased oil protein 14 29 application dramatically decreased 44 88 16 38 57 addition significantly lowered concentration exchangeable (Exc) bound carbonate (B-C) fractions while iron-manganese (B-Fe-Mn) bounded residual (Res) fractions. conclusion, amendment could be used as sustainable approach ecological environmental risks associated soils contaminated Cr, ensure safer crop production.
