“…Biochar is a solid compound that results from organic matter decomposition under high temperatures under low oxygen concentrations in a pyrolysis process (Lehmann et al, 2011). Silva et al (2021) has studied the use of biochar as a low-cost alternative for waste reuse in agriculture, benefiting the soil, microorganisms, culture, and the environment. Biochar improves the soil physical, chemical, and biological parameters.…”

A better understanding of the use of biochar with Trichoderma spp. (TRI), considered the most studied tool for biological control, would increase our ability to set priorities. However, no studies exist using the two inputs on plant disease management. Here, we hypothesized that biochar and TRI would be used for the management of soilborne plant pathogens, mainly due to changes in soil properties and its interactions. To test this hypothesis, this review assesses papers that used biochar and TRI against plant diseases and we summarize the handling mechanisms for each input. Biochar acts by mechanisms: induction to plant resistance, sorption of allelopathic and fungitoxic compounds, increase of beneficial microorganisms, changes the soil properties that promote health and nutrient availability. Trichoderma as biocontrol agents by different mechanisms: mycoparasitism, enzyme and secondary metabolic production, plant promoter agent, natural decomposition agent, and biological agent of bioremediation. Overall, our findings expand our knowledge about the reuse of wastes transformed in biochar combined with Trichoderma has potential perspective to formulate products as alternative management tool of plant disease caused by soilborne fungal pathogen and add important information that can be suitable for development of strategy for use in the global health concept.

“…Moreover, in the context of climate change with forecast increases in extreme rainfall events and longer dry periods, it is essential to hold water and nutrients in order to conserve or increase soil fertility. To preserve and maximize the efficiency of scarce water and nutrient resources of these marginal lands, the use of biochar can be a promising sustainable solution (de Melo Carvalho et al, 2014;Dharmakeerthi et al, 2010;Lima et al, 2018Lima et al, , 2021Medeiros et al, 2020;Silva et al, 2021).…”

“…An increasing number of publications around the world have reported the effect of biochar amendments on all kind of soils under different climates (Adekiya et al, 2019; Al‐Wabel et al, 2018; Farhangi‐Abriz et al, 2021; Kavitha et al, 2018; Lima et al, 2018, 2021). Initially inspired by the Amazonian dark soils, ‘Terra Preta do Indio’, it is advocated to restore the fertility of tropical soils and especially in acidic sandy soils (Glaser & Birk, 2012; Lehmann et al, 2006; Lima et al, 2018; Silva et al, 2021). More generally biochar is the carbon‐rich product obtained when biomass, obtained from wood or plant waste feedstocks, is pyrolysed in oxygen‐free conditions (Lehmann & Joseph, 2015).…”

Pradoo wood biochar has been tested in order to explore sustainable solutions to the development of agriculture on poor sandy soils in marginal areas in Northeast Thailand. Some basic physicochemical properties of biochar, for example pore size distribution, cation exchange capacity (CEC), specific surface area (SSA), and water and nutrient adsorption, were determined and compared to soil properties in order to determine appropriate biochar application to soil. Pradoo wood biochar showed important adsorption properties with high SSA, CEC and nutrient adsorption. The water retention properties were also improved on the dry end of the water retention curve. Phosphorous and ammonium adsorption–desorption isotherms were established and their respective affinity for the biochar surface was quantified, by the means of a retention index and thermodynamical parameters. We found that despite excellent retention properties, biochar needs to be added in large amounts (between 10 and 70 kg m−2) to soil to be able to modify noticeably the resulting soil properties.
