Implementation of biochar in plants to improve their abiotic stress resilience
Abstract
Biochar is a sustainable material that can boost agricultural yields and has enormous potential for application worldwide to improve stress tolerance. Crop yield, ecosystem sustainability, and soil health are all significantly impacted by biochar. It affects the diversity, composition, and functional soil microbial communities. The physicochemical characteristics of soil, including pH, organic matter, and nutrient availability, are also affected. It may increase a crop's resistance to abiotic stresses such salt, drought, and extremely high or low temperatures. It enables crops to tolerate stress by triggering hormonal regulation, osmotic adjustment, and antioxidant defence. Crop stress tolerance and its function in regulating the soil microbiota have significant ramifications for sustainable agriculture. It is a useful instrument for enhancing agricultural sustainability because of its advantages for crop productivity and stress tolerance. Biochar can increase crop yields, lessen soil degradation, and support ecosystem services when used in agriculture. As a result, this analysis advances our knowledge of the connections among biochar, soil microbiota, and crop resilience while highlighting biochar's potential as a useful supplement for enhancing crop stress tolerance
