WebOct 28, 2014 · Amending polycyclic aromatic hydrocarbon (PAH)-contaminated soils with biochar may be cheaper and environmentally friendly than other forms of organic materials. This has led to numerous studies on the use of biochar to either bind or stimulate the microbial degradation of organic compounds in soils. However, very little or no attention … WebNov 12, 2024 · Rezaie et al. ( 2024) noted that applying 2.5% biochar to soil (w:w), then irrigating with water having an electrical conductivity (EC) of 5 dS m −1, helped to improve faba bean yield. Elshaikh and She ( 2024) applied 0, 5, and 10% biochar to soil, and then irrigated with increasing NaCl containing solutions (up to 7.0 dS m −1 ).
