“…Increases in soil exchangeable K (Exhibit 7) have resulted from the easy release of this nutrient from biochar (Figueredo et al., 2017). Conversely, increases in available P (Exhibit 7) may be due to the interaction of different mechanisms, such as: (i) increase in soil pH (Glaser & Lehr 2019); (ii) direct release of P from biochar, and residual biochar ash, especially in biochar derived from ash‐rich feedstocks containing P, such as animal waste (Online resource 1); (iii) reduction of P sorption in the clay fraction of biochar‐treated soils (Glaser & Lehr 2019); and (iv) effect of biochar on favoring the population of P‐solubilizing bacteria (Caniato et al., 2020; Zheng et al., 2019). Brazilian soils have shown a wide variation in P adsorption capacity and clayey soils usually has high P adsorption capacity (Poggere et al., 2020).…”

Biochar has been intensively researched worldwide. In Brazil, there is a variety of feedstock production that can be turned into soil amendments of high performance through biochar conversion, especially solid wastes. However, advances in biochar research in Brazil have not been systematically evaluated to indicate possible gaps and suggest future research for eco-friendly applications. Thus, in this work we evaluated biochar properties and effects on air, water, and soil quality based on data gathered from researches performed in Brazil. Biochar has been mainly evaluated as soil conditioner (37%), material characterization (17%), water treatment (12%), and greenhouse gases emissions (9%). Based on the data synthesis of 68 feedstocks used for biochar production, we observed that the pyrolysis temperature profoundly affects biochar properties. Meta-analysis indicated benefits of biochar addition to soils for chemical, physical, microbiological and biochemical attributes that have resulted in increases in root growth (+30%), and plant shoots (+45%). Pyrolysis temperature and feedstock are key choices to design biochar properties aiming to retain dyes, aromatic hydrocarbon, pesticides, and metals in water and wastewater treatment. It was also observed an increase in CO 2 and a decrease in N 2 O emissions after biochar application to soils in short-term experiments. Although there is a growing interest in the development of electrochemical sensors and biochar-based fertilizers, technological applications of biochar are still incipient in Brazil. Future research should prioritize long-term and mechanistically evaluations of biochar under field conditions and the development of eco-friendly technological applications.
