“…These positive results of essential nutrients might be due to the pronounced effects of biochar on soil organic carbon and the physical properties of soil that improved the soil retention capacity to prevent the nutrients leaching and increased the availability of these essential nutrients in biochar treated soil. The current results of our study can be correlated with increased cation and anion exchange capacities under biochar addition (Mavi et al, 2018), which caused a decrease in nutrient loss from soil and increased retention and concentrations of NO − 3 -N and NH + 4 -N (Abbruzzini et al, 2019). The biochar amendment can also cause negative and adverse effects on soil nutrients availability due to the high C:N ratio of biochar which can increase immobilization of nitrogen in the soil and decrease the availability of N for plant uptake (Lehmann and Joseph, 2012).…”

The amendment of biochar has been proposed to improve soil fertility and crop yield. However, consolidated information lacks explaining the role of biochar on soil and plant enzymatic activities involved in nutrients cycling in soil and accumulation in plants improving utilization of applied inorganic fertilizer and crop growth. In the current study, we evaluated the integral effects of biochar levels (B0:0, B15:15, B3:30, and B60:60 t ha–1) and nitrogen fertilizer levels (N0:0, N75:75, N225:225, and N450:450 kg ha–1) on soil physicochemical properties, enzymatic activities, nitrogen use efficiency (NUE) and grain yield of rapeseed for 2 years in the pots during 2020 and 2021. The findings revealed that compared to control (B0 + N0), a combination of B30 + N450 increased soil urease activity by 73 and 75%, and B60 + N450 increased activities of soil catalase by 17 and 16%, and B60 + N225 increased alkaline phosphatase by 17 and 19%, respectively, in the first and second year. Moreover, a single application of high nitrogen at 450 kg ha–1 reduced the activities of plant nitrogen metabolism-related enzymes, however; the integration of biochar at 30 t ha–1 compensated the high nitrogen toxicity and improved the activities of nitrate reductase (NR), nitrite reductase NIR, glutamate synthase (GS) and glutamine synthetase (GOGAT) at seedling stage (SS) and flowering stage (FS) in both years. The integration of biochar at 30 t ha–1 with nitrogen at 450 kg ha–1 induced synergetic effects on rapeseed growth through sorption of excessive nitrogen in soil and significantly improved the plant height up to 11 and 18%, pods plant–1 39 and 32% and grain yield plant–1 54 and 64%, respectively, during the first and second year. Moreover, biochar at 15 t ha–1 along with nitrogen at 225 kg ha–1 resulted in the highest NUE of 29% in both years suggesting that biochar can also offset the deficiency of lower nitrogen. This study highlighted the ameliorative effect of biochar suppressing high nitrogen toxicity and decreasing lower nitrogen deficiency effects on rapeseed growth by improving nitrogen use efficiency via enhancing soil conditions, enzymatic activities and soil nitrogen utilization potential and thus improving rapeseed growth and yield.

“…Furthermore, compared to control, plant height, tillers number, and leaf area were significantly enhanced under the combined application of biochar and nitrogen fertilizer than the single application of either biochar or nitrogen fertilizer, which might be due to high and increased nutrients availability (Table 4). Generally, the availability and uptake of nitrogen greatly influence the aboveground biomass of plants by promoting tillering before stem extension, and the stored nitrogen in plant biomass redistribute from leaves and stem for grain protein formation during the grain filling stage (Abbruzzini et al, 2019; Hgca, 2008; Ullah et al, 2021). The possible mechanism for this might be due to the high binding forces in soil with high biochar concentration that decreased the availability of the nutrients and increased the salt concentration due to its liming effect.…”

The quality and nutritional status of agricultural soils are depleting gradually, and biochar is widely used in soil quality improvement. A sustainable approach of biochar application needs a better understanding of its interaction with nitrogen application and the final effect on crop growth. In our study, the effect of different biochar application levels (0, 15, 30, and 60 tons ha−1) in combination with nitrogen fertilizer levels (0, 150, 300, and 450 kg ha−1) on soil properties, rice growth, and nitrogen use efficiency were investigated. The results showed that sole application of biochar (B60) did not promote the rice growth except the soil organic carbon (SOC), total nitrogen, total phosphorous, and available potassium compared with no biochar addition, while a single application of 450 kg N ha−1 (N450) adversely affected the rice physiological and yield traits by destroying rice leaf ultrastructure and reducing the stomatal length by 13%, stomatal width 3% and density 12%, plant height 5%, dry biomass plant−1 4%, spike weight plant−1 8%, and grain weight plant−1 9% compared to N300 unless it was treated in combination with biochar. Biochar can significantly compensate the toxicity of excessive nitrogen and deficiency of low nitrogen fertilizer on rice growth. Compared to a single application of B0+N450 (450 kg N ha−1), combined application of biochar and nitrogen B30+N450 could elevate rice plant nitrogen content by 13%, plant height 30%, aboveground dry biomass plant−1 136%, spike weight plant−1 34%, and grain weight plant−1 36% while increments in total nitrogen accumulation (TNA 79%%) and nitrogen use efficiency (NUE 35%) were noted in B30+N300 treatment. These results suggest that biochar amendment combined with a proper amount of nitrogen fertilizer is an effective approach to promote soil conditions, manage nitrogen utilization, improve plant growth and increase crop yield on a sustainable basis.

“…Furthermore, the interaction between soil and biochar can affect the N transformations in the soil profile by changing its CEC, porosity, aeration, pH, and microbial activity [173]. Abbruzzini et al [174] reported that biochar applied at 0.4-1.9% (w/w) with N fertilizer reduced N 2 O emissions up to 71% compared to soil where N was applied without biochar. Moreover, biochar enhanced the available P by 30% and increased wheat grain yield by 27% and shoot biomass by 16% compared to un-amended soil with biochar.…”

Biochar is gaining significant attention due to its potential for carbon (C) sequestration, improvement of soil health, fertility enhancement, and crop productivity and quality. In this review, we discuss the most common available techniques for biochar production, the main physiochemical properties of biochar, and its effects on soil health, including physical, chemical, and biological parameters of soil quality and fertility, nutrient leaching, salt stress, and crop productivity and quality. In addition, the impacts of biochar addition on salt-affected and heavy metal contaminated soils were also reviewed. An ample body of literature supports the idea that soil amended with biochar has a high potential to increase crop productivity due to the concomitant improvement in soil structure, high nutrient use efficiency (NUE), aeration, porosity, and water-holding capacity (WHC), among other soil amendments. However, the increases in crop productivity in biochar-amended soils are most frequently reported in the coarse-textured and sandy soils compared with the fine-textured and fertile soils. Biochar has a significant effect on soil microbial community composition and abundance. The negative impacts that salt-affected and heavy metal polluted soils have on plant growth and yield and on components of soil quality such as soil aggregation and stability can be ameliorated by the application of biochar. Moreover, most of the positive impacts of biochar application have been observed when biochar was applied with other organic and inorganic amendments and fertilizers. Biochar addition to the soil can decrease the nitrogen (N) leaching and volatilization as well as increase NUE. However, some potential negative effects of biochar on microbial biomass and activity have been reported. There is also evidence that biochar addition can sorb and retain pesticides for long periods of time, which may result in a high weed infestation and control cost.
