“…Nitrous oxide emissions were detectable only at very few occasions. Low to absent N 2 O emissions are in line with field measurements conducted at the Traismauer site from June 2011 to September 2012 (Soja et al., 2013). The general lack of detectable N 2 O emissions may be explained by soil conditions favorable for the reduction of N 2 O to N 2 , that is, a high pH (7.5), sufficient C available for complete denitrification as suggested by EOC/NO 3 ratios (Table 2) markedly above the minimum supply C/N ratios for heterotrophic microorganisms (≈ 3), and the positive relation between N 2 fluxes and NO 3 –N concentrations (Lan et al., 2017; Zhang et al., 2020).…”

Four years after a single biochar (BC) application of 72 t ha−1, significantly higher N2 fluxes were measured from BC‐treated soil using the helium gas flow soil core method compared with the control. Nitrous oxide was below the detection limit. Soil moisture and temperature significantly affected N2 fluxes, which were highest at 70% water‐filled pore space and 5°C. The BC‐treated soil was characterized by higher organic C and NO3–N concentrations and a wider C/N ratio of the microbial biomass.

“…In addition to directly supplying nutrients, biochar can help retain critical soil nutrients by decreasing losses from leaching (Laird et al, 2010). Nitrogen runoff, for example, decreases in temperate soils due to the adsorption by the char (Dong et al, 2020; Laird et al, 2010; Soja et al, 2016; Zheng et al, 2017). Randolph et al (2017) studied over 30 different agricultural‐waste biochars produced at different pyrolysis temperatures and rates, and found that all but one feedstock decreased

Produced through pyrolysis, biochars are used as a soil amendment. Differences in feedstock and processing result in differentiated products which impact their values in different soil conditions. Despite the enormous potential, biochars have not been widely used. This paper overviews the benefits and potential demand for biochar and features of supply chain, and identifies opportunities for viable introduction of biochars. The value of biochars should be evaluated as a part of the pyrolysis system that coproduces biochars and biofuels. Biochars can improve agricultural productivity and soil functioning and contribute to climate change mitigation through carbon sequestration. Furthermore, it can provide extra benefit by contributing to fire prevention. The cost of biochar system depends on the costs of feedstock acquisition, transportation, and processing. Biochar is most likely to be adopted in locations with marginal land and high‐value crop, and near low‐cost feedstock sources. The adoption of biochar can be enhanced by compensation for carbon sequestration, further investment in research, and learning of producers to enhance efficiency of the supply chain.
