“…Moreover, the CO 2 efflux of the BC1 and BC4 treatments decreased in the early stage but rose abruptly on the 9th day, because the CO 2 efflux from biochar was highest on that day, but it should be noticed that the CK treatment also increased, indicating that other mechanisms may exist which are worthy of further study. Throughout the incubation period, the CO 2 emissions of BC1 and BC4 were lower than those of CK, which was in line with the studies by Sakin et al [16] and Herath et al [13]. The ability of biochar addition to reduce soil CO 2 emissions was attributed to the negative priming effect of biochar addition on native SOC mineralization [46,47].…”

“…Meanwhile, Tang et al [10] found that CO 2 emissions increased with the increasing biochar addition ratio. However, some investigations contradict the conclusions shown above [13][14][15][16]. For example, Sakin et al [16] found that biochar addition reduced soil CO 2 emissions, and the CO 2 emissions were lowest at the highest addition ratio.…”

For example, Sakin et al [16] found that biochar addition reduced soil CO 2 emissions, and the CO 2 emissions were lowest at the highest addition ratio. It has also been found that biochar addition reduced CO 2 emissions in forest soil but had no significant effect on CO 2 emissions in grassland soil [7].…”

Biochar addition has been recommended as a potential strategy for mitigating climate change. However, the number of studies simultaneously investigating the effects of biochar addition on CO2, N2O and CH4 emissions and sequentially global warming potential (GWP) is limited, especially concerning its effect on native soil organic carbon (SOC) mineralization. An incubation experiment was conducted to investigate soil physicochemical properties, CO2, N2O and CH4 emissions and GWP in the treatments with 0% (CK), 1% (BC1) and 4% (BC4) cornstalk biochar additions, and clarify the priming effect of biochar on native SOC mineralization by the 13C tracer technique. Generally, biochar addition increased soil pH, cation exchange capacity, SOC and total nitrogen, but decreased NH4+-N and NO3--N. Compared with CK, BC1 and BC4 significantly reduced CO2 emissions by 20.7% and 28.0%, and reduced N2O emissions by 25.6% and 95.4%, respectively. However, BC1 significantly reduced CH4 emission by 43.6%, and BC4 increased CH4 emission by 19.3%. BC1 and BC4 significantly reduced the GWP by 20.8% and 29.3%, but there was no significant difference between them. Biochar addition had a negative priming effect on native SOC mineralization, which was the reason for the CO2 emission reduction. The negative priming effect of biochar was attributed to the physical protection of native SOC by promoting microaggregate formation and preferentially using soluble organic carbon in biochar. The N2O emission decrease was rooted in the reduction of nitrification and denitrification substrates by promoting the microbial assimilation of inorganic nitrogen. The inconsistency of CH4 emissions was attributed to the different relative contributions of CH4 production and oxidation under different biochar addition ratios. Our study suggests that 1% should be a more reasonable biochar addition ratio for mitigating greenhouse gas emissions in sandy loam, and emphasizes that it is necessary to furtherly investigate nitrogen primary transformation rates and the relative contributions of CH4 production and oxidation by the 15N and 13C technique, which is helpful for comprehensively understanding the effect mechanisms of biochar addition on greenhouse gas emissions.

“…In our study, the effects of different AMFs on CAT, DGH, and urease enzymes were generally different from the control and these changes were statistically significant (p < 0.05). Urease is an agent that catalyzes the hydrolysis of soil-applied urea or existing urea to ammonia, causing the release of NH 3 and pH increase, and is also the first step of the nitrification process [ 56 ]. In our study, there was a statistically significant correlation between urease and NH 4 + (r = 0.38, weak positive), APA enzyme (r = 0.36, weak positive), and N plant (r = 0.51, moderate positive) ( Fig.…”

“…Shahzad et al (2014) reported an increased activity of phosphatase on biochar addition, which signify greater proportion of bio-available phosphorus. Sakin et al (2021) reported that addition of almond shell biochar had significant positive effect on dehydrogenase and urease activities. Jing et al (2020) reported no significant correlation between enzyme activity and soil organic carbon.…”

Intensive cultivation of agricultural soils causes soil degradation which emphasizes the need for sustainable soil management. Biochar, a pyrolysed carbon rich material has gained great interests among the researchers because of its eco-friendly benefits in addition to soil quality enhancement. Reviews on biochar, mainly confined to its environmental benefits like carbon sequestration and climate change. In this review, we summarize i) the effect of biochar application on soil properties (physical, chemical, biological), ii) remediation potential of biochar in heavy metal contaminated soils and iii) its impact on crop productivity. The properties of biochar like pH, greater surface area, cation exchange capacity, and nutrient content positively influences the soil properties and ultimately improves the soil fertility. Their effectiveness depends on biochar type, its dosage, soil type, etc. General trends from this review indicated that biochar as an effective amendment in acid soils than the alkaline or calcareous soils. Furthermore, the biochar effects are studied mostly under controlled conditions in laboratory, which needs to be validated under field conditions having varied soil types and agro-climatic zones.
