“…Application of biochar at the rate of 2%-5% has been reported to increase the carbon sequestration significantly by 46%-58% from rice and beet fields (Lai et al, 2013). Biochar derived from apple wood residues and re-applied in apple orchards promoted the soil organic carbon sequestration, which increased by 316.52%-354.78% in a 2-year study in the Loess Plateau of China (Han et al, 2022). Soil carbon sequestration was increased significantly (1.87-13.37 t C/ha) under wood-derived biochar application, compared to rice straw application which reduced carbon sequestration, driven by highly recalcitrant carbon contained in biochar vs. labile form in rice straw (Thammasom et al, 2016).…”

“…Soil amendment with biochar is regarded as one of the important ways to improve soil nutrient and water retention and promote soil ecological functioning, as well as a significant tool to combat climate change issues by storing the CO 2 back in the earth (Woolf et al, 2010;Lorenz and Lal, 2014;Han et al, 2022). Because of the highly stable carbon content with high porosity and specific surface area, its application can provide a multitude of benefits as a soil amendment (Lehmann, 2007;Oni et al, 2019;Das et al, 2021;Zhang et al, 2021).…”

“…Biochar amendment with small and medium particle size considerably decreased the soil pH and electrical conductivity (Zeeshan et al, 2020). Additionally, the tiny particle size fraction greatly enhanced the soil's organic matter (OM) content and saturation (Gorovtsov et al, 2020;Han et al, 2022).…”

“…Applying biochar enriched with nitrogen at 4 ton ha -1 promoted rice yields while reducing greenhouse gas emissions (Yin et al, 2021). Biochar derived from apple wood residues and re-applied in apple orchards reduced the net greenhouse gas emission (net global warming potential) by 368.93%-480.91% in a 2-year study in the Loess Plateau of China (Han et al, 2022). A meta-analysis of global biochar application has revealed that biochar, when applied without and with chemical fertilization, reduced the global warming potential by 27.1% and 14.3%, respectively, by reducing the net greenhouse emissions (Xu et al, 2021).…”

With the global food deficit increasing and rising climate change issues, there is a need to find green solutions to improve soil fertility and productivity while enhancing soil biochemical quality and reducing the ecological impact of agriculture. Biochar is a potentially cost-effective, carbonaceous resource with many agricultural and environmental applications. As a soil amendment, it improves soil physical and biochemical properties and increases soil fertility and productivity—particularly over the long-term—increasing soil aggregation, water retention, pH, and microbial activities, thus, improving overall soil quality, potentially helping to reduce chemical fertilizer needs over time. The extent of biochar’s impact on soil physiochemical properties varies depending on biochar source, type, size, inherent soil characteristics, cropping system, etc. Moreover, biochar has significant potential in soil and water remediation, especially through its unique adsorption and chemical properties capable to capture and immobilize pollutants such as metal(loid)s, organic pollutants, and hazardous emerging contaminants such as microplastics. Further, biochar has also emerged as a key strategic, cost-effective material to tackle global issues such as climate change mitigation, reducing the net greenhouse gas emission to minimize global warming potential. However, a knowledge gap remains as to understanding the long-term persistence of biochar on agroecosystem, optimal biochar application rate for the diversity of biochar-soil-crop-environmental conditions, interaction of biochar with inherent soil carbon stock, specific mechanisms of biochar’s effect on soil biotic properties, quantification of carbon sequestration, greenhouse gas emissions, synergy or potential antagonistic effects with other carbon sources such as compost, manure, residues, etc., its modification for environmental applications and associated environmental and human risks over long-term. Further research is needed to evaluate the long-term impacts of types and sizes of biochar on overall soil quality to recommend suitable application practices based on soil management and cropping system. Also, its environmental applications need to be finetuned for wider and target specific applications to tackle pressing environmental issues such as soil and water pollution.

“…Biochars, which are the carbonaceous residues of organic biomass carbonization in the absence of oxygen, have been identified as promising and eco-friendly materials for agricultural soil amendment and soil conditioning [11][12][13][14]. Indeed, it has been clearly reported that these materials: (i) have slow release capacities for the contained nutrients, (ii) significantly improve agricultural soils' physico-chemical, biological and hydrodynamic properties, (iii) present high carbon sequestration potential and low CO 2 emissions to the atmosphere.…”

This work examines in silico the dominant geochemical processes that control inorganic nutrients (Ca, Mg, Na, K) availability in irrigated agricultural soil amended with potassium-enriched biochar (from olive mill wastes) at mass doses of 0.5%, 1%, 2% and 10%. The geochemical modelling step was supported by analytical measurements regarding the physicochemical characteristics of the irrigation water, the agricultural soil and the biochar. Two geochemical approaches, namely equilibrium exchange (E.E.) and kinetic exchange (K.E.) models were applied and compared to assess nutrient release with an emphasis on potassium availability. Equilibrium exchange perspective assumed that nutrient release is controlled by ion-exchange reactions onto the biochar surface, whilst kinetic exchange perspective assumed the contribution of both ion-exchange and dissolution of salts. Results indicated that for the E.E. model, the soluble amount of potassium is readily available for transport within the pores of the porous media, and therefore is leached from the column within only 10 days. For the K.E. model that assumes a kinetically controlled release of potassium due to interactions occurring at the solid-solution interface, the assessed retention times were more realistic and significantly higher (up to 100 days). Concerning the applied doses of biochar, for a 2% biochar fraction mixed with soil, for example, the available K for plants doubled compared with the available K in the soil without biochar. In any case, the use of numerical modeling was proven helpful for a quick assessment of biochar performance in soil, by avoiding time-consuming and laborious experimental set-ups. Validation of the models by experimental data will further establish the proposed mechanisms.
