“…In general, manure and sludge-based BCs possess higher pHs than wood-based BCs because their ash fractions contain higher proportions of alkali metals (mainly Na and K) Srinivasan et al, 2015). Functional groups (-OH, -COOH groups) that primarily determine BC reactivity and raise soil CEC, collapse at high PTs (> 500°C) ( Table 1; Cheng and Lehmann, 2009;Singh et al, 2010;Subedi et al, 2016aSubedi et al, , 2016b.…”

“…On the other hand, nutrient retention and availability relate to BC adsorption capacity Ippolito et al, 2015;Zornoza et al, 2016). Overall, manure-and sludge-based BCs are richer in plant available nutrients as compared to grass-and wood-based BCs, which is mostly a reflection of their original feedstock properties, although C, N, and S losses at high PTs are unavoidable Jensen, 2013b;Subedi et al, 2015Subedi et al, , 2016aSubedi et al, , 2016b. Other nutrients (P, K, Ca, Mg, and Na) found mainly in the ash fraction, are plantavailable depending on the soil-BC matrix, pH, and the presence of chelating substances that regulate their mobilisation (Cui et al, 2011;Wang et al, 2015).…”

Nitrogen content and availability correlates highly to PT, rate of heating, and feedstock type and composition (Wang et al, 2012a;Clough et al, 2013;Subedi et al, 2016b). Differential response to PTs showed that at low PT (<400ºC) BCs favour greater recovery of C and other nutrients (both macro and micro) compared with high PT (>400°C) BCs because these nutrients are increasingly lost at higher PTs.…”

Crop response to soils amended with biochar: expected benefits and unintended risks

Biochar (BC) from biomass waste pyrolysis has been widely studied due to its ability to increase carbon sequestration, reduce greenhouse gas emissions, and enhance both crop growth and soil quality. This review summarises the current knowledge of BC production, characterisation, and types, with a focus on its positive effects on crop yield and soil properties vs the unintended risks associated with these effects. Biochar-amended soils enhance crop growth and yield via several mechanisms: expanded plant nutrient and water availability through increased use efficiencies, improved soil quality, and suppression of soil and plant diseases. Yield response to BC has been shown to be more evident in acidic and sandy soils than in alkaline and fine-textured soils. Biochar composition and properties vary considerably with feedstock and pyrolysis conditions so much that its concentrations of toxic compounds and heavy metals can negatively impact crop and soil health. Consequently, more small-scale and greenhouse-sited studies are in process to investigate the role of BC/soil/crop types on crop growth, and the mechanisms by which they influence crop yield. Similarly, a need exists for long-term, field-scale studies on the effects (beneficial and harmful) of BC amendment on soil health and crop yields, so that production guidelines and quality standards may be developed for BCs derived from a range of feedstocks.

Due to environmental issues, many methods of exploiting renewable natural resources are alternatives to reduce the dependence on non‐renewable agricultural inputs. Phosphate fertilization on weathered tropical soil and waste reuse, for example, requires better management strategies. Thus, biochar from organic residues can be a strategy to reduce pressure on natural resources, in addition to having the potential to mitigate climate change. This study aimed to evaluate the availability of P in tropical soils from the interaction of biochar and arbuscular mycorrhizal fungi (AMF) in the aboveground and root systems of the plant and its impact on greenhouse gas (GHG) emissions. The results indicated that the addition of biochar was an alternative for C sequestration and GHG mitigation, causing no damage to the plant. The applied biochar amount had, for the most part, emission equal to or less than the control treatment (soil only). The sugarcane straw biochar (BCS) showed higher emissions, mainly in the presence of P and AMF. Biologically speaking, there was no significant effect in the presence of mycorrhizae. However, with regard to plant production, treatments where mycorrhizae were inoculated, longer and wider leaves were found. In the production of maize (Zea mays L.) plant material (aboveground and root), the upper and lower values were related to the poultry manure biochar (BPM) , and the presence of P, the values were lower, indicating that, for the good development of the plant, only the presence of the biochar is sufficient, without requiring the addition of phosphate fertilizer.
