Abstract: Globally, agriculture is the backbone of farmers and plays a crucial role in food security, for a world with increasing population and food demand. As we know that the world’s population is increasing rapidly every year, so the supply of food for the alarmingly increasing world population has become a serious problem. Food insecurity is aggravated by changing climatic conditions, soil degradation, and loss of arable lands due to various abiotic stresses, including salinity. Salinity greatly affects the world’s agricultural lands due to various factors such as low availability of fresh and salt-free water, high temperature, etc. The salinity is caused by both primary and secondary processes. Primary salinity is mainly caused by many natural processes while secondary is mainly caused by human activities. Salinity is a land degradation process, characterized by a high concentration of soluble salts in the soil. It can suppress crop growth by influencing various functions and processes of plants, ultimately leading to significant yield reduction. Biochar is an organic-based material that helps to remediate soil salinity by various mechanisms in the soil system. Biochar has the potential to enrich microbial diversity and enhance activity which plays a vital role in the improvement of soil physical, chemical, and biological activities enhancing the productivity of the crops. The present review contains extensive details about salinity and its remediation using biochar.
Keywords: Abiotic stress, biochar, carbon-rich material, carbon sequestration, food security, microbial activity, plant growth, salinity, soil salinity, sustainable agriculture, water availability to plants.
