“…The combination of Bch and AMF stimulates root growth, increases the contact between soil and root and causes more access to soil nutrients [11]. Some reports indicate that the interactions of Bch and different microorganisms can be used to improve nutrient absorption and plant productivity through different mechanisms [55]. It has also been reported that the use of silicon and mycorrhizal fungi will reduce the absorption of toxic sodium ions, improve the conditions of the rhizosphere, increase the absorption of nutrients and regulate plant metabolic processes [17].…”

“…It has been reported that the use of Bch affects the absorption of nutrients and water and causes an increase in RWC and a decrease in ion leakage under salinity stress conditions . Also, the combination of Bch and AMF improves growth and water absorption by inducing the expression of speci c genes and balancing plant hormones [52][53][54][55][56][57][58][59][60].…”

In the studies that have been conducted on resources that increase tolerance to salt stress, their individual use has often been considered. There is little evidence of their synergistic effects, especially for plants grown in saline soil conditions. In this research, a factorial experiment was conducted in the randomized complete block design in 2020 and 2021. The rst factor was 3 maize varieties including 704, 604 and 370 and the second factor was resources ameliorating the adverse effcts of salinity including control, single, dual and combined use of biochar (Bch), arbuscular mycorrhizal fungus (AMF) and silicon foliar application (SiFA). The results showed that leaves sodium concentration in the combined treatment of Bch + AMF + SiFA decreased by 13% compared to the control. In 704 the concentration of potassium and nitrogen in the combination of Bch + AMF + SiFA respectively showed an increase of 25 and 22% compared to the control. Also, dual consumption of ameliorating resources caused an increase in leaf iron, zinc, copper and manganese. Combined use of ameliorating resources decreased ion leakage and increased the relative water content and the photosynthetic pigments. In 604 and 370, the grain yield was respectively increased by 10 and 18% in the combination of Bch + AMF + SiFA compared to the control. Considering the positive effect of ameliorating resources in improving seed yield and seed oil percentage, the combination of biochar + mycorrhiza + silicon can be recommended under salt stress.

“…Bio char functions as a carbon sink, capturing and storing carbon, thereby mitigating greenhouse gas emissions. It also acts as a potent soil amendment, enhancing soil structure, fertility, and water retention capacity, resulting in improved soil health, increased nutrient availability, and reduced nutrient leaching [14]. Biochar's porous nature fosters a rich microbial community, aiding in nutrient cycling and disease suppression.…”

Crop resilience is crucial in the face of climate change, as agricultural regions face unprecedented challenges such as rising global temperatures, altered precipitation patterns, and increased extreme weather events. These changes impact food security, crop yields, and the livelihoods of millions of farmers worldwide. Crops face threats from heat stress, changing pest and disease dynamics, water scarcity, and unpredictable growing seasons. Crop resilience involves a complex interplay of genetics, environmental factors, and agricultural practices. Researchers and agricultural scientists are exploring innovative approaches like selective breeding, genetic modification, and precision agriculture to enhance crop resilience. Integrating traditional knowledge and indigenous farming practices into modern agricultural strategies is essential for securing food production, ensuring the sustainability of agricultural systems, conserving biodiversity, and supporting community resilience in an uncertain climate future. Crop resilience is central to ensuring global food security, supporting rural livelihoods, preserving ecosystems, and advancing sustainable agriculture in the face of climate change challenges. Biochar, a climate-resilient agricultural amendment, is gaining attention for its role in enhancing agricultural sustainability and mitigating climate change. Its porous structure and high carbon content sequester carbon dioxide, improve soil health, and reduce nutrient leaching. Biochar's porous nature fosters a rich microbial community, aids in nutrient cycling, and aids in rehabilitating degraded soils. It also reduces synthetic fertilizer requirements and environmental pollution. Climate change significantly impacts crop agriculture, disrupting traditional growth patterns and threatening global food security. High temperatures cause heat stress, while droughts and floods cause soil desiccation, impairing crop yields. Increased plant diseases and pests spread, while higher CO2 levels stimulate photosynthesis but reduce essential nutrients. Rising temperatures disrupt vegetative and reproductive growth phases, pollination, and seed formation, compromising crop quality and market value. Biochar is a porous material formed through pyrolysis, a process where organic biomass is decomposed under limited oxygen conditions. It is primarily carbon-rich but contains hydrogen, oxygen, nitrogen, and minerals. As a soil amendment, biochar is a stable carbon sink with a high carbon content of 70-90%. Its porous structure allows it to efficiently adsorb and retain water, nutrients, and organic compounds. Its large surface area facilitates interactions with soil microbes and nutrient ions, and its high CEC helps in nutrient retention and soil fertility.

“…Biochar also shields soil bacteria from the harmful impacts of organic and inorganic contaminants. Biochar increases the efficacy of numerous microorganisms such as plant growth-promoting rhizobacteria and phosphorus-solubilizing bacteria a result of favourable biochar-microbe interactions, which promotes agricultural yield through a variety of features [32]. Biochar influences soil microbial activity and biomass, alters soil bacteria-fungi ratios and enzyme activity, and reshapes the microbial community structure.…”

Soil health plays a crucial role in agricultural productivity, environmental sustainability, and global food security. In recent years, biochar has emerged as a promising soil amendment due to its ability to enhance soil fertility, nutrient retention, water holding capacity, and overall soil health. From an agricultural standpoint, using biochar as a soil conditioner has various advantages, including improved physical, chemical, and biological qualities of soils, which leads to enhanced crop output. Biochar can be utilised for soil carbon sequestration, reducing the bioavailability of pollutants impacting living organisms, and water treatment due to its physicochemical qualities This review paper aims to provide an in-depth analysis of the role of biochar in improving soil health.
