Biochar-based fertilizers are a new attractive alternative to P supplementation for crops, as they can gradually release the nutrient, avoiding losses and improving soil quality. In this regard, the evaluation of the P amount in biochar-based fertilizers is extremely important for their quality control. Analytical techniques that require sample solubilization are not very efficient for …

Biochar amendment had minimal effects on uptake of nano-ceria by crop plants. Biochar production temperature (350°C or 600°C) and to a lesser extent, soil type, had the greatest impact on uptake, pigment production and lipid peroxidation, especially at the highest doses of nano-ceria, which are environmentally unrealistic.

The modified biochar prepared by H 2 SO 4 produced a large amount of C═O (C3). The production of C3 was due to the high oxidation state of C in the C═O and HO–C–OH structures, which produced a large amount of ketones. Analysis showed that the strong oxidation of sulfuric acid led to an increase in double bonds.

Ash-biochar composites with high alkalinity increase soil pH, favouring the electrostatic interactions for metallic cations and negatively charged soil colloids (Lei et al., 2020). Nano zero valent iron– and iron sulphide–biochar composites promote soil Cr(VI) reduction (Liu, Yang, et al., 2020; Lyu, Zhao, et al., 2018; Wang et al., 2019).
