Saline-alkali soil has become significant problem for global agriculture and food security as these soils have poor physicochemical conditions reduce crop production by causing a wide range of physiological biochemical changes in plants. More than 800 million hectares (Mha) land throughout the world affected saline-alkali soil, which accounts 6% total area about 62 Mha or 20% world's irrigated is soil. Numerous studies on been conducted years an attempt to plant productivity losses. Utilizing sewage sludge (SS) efficient way improve its physiochemical properties soil's health yield. However, in-depth mechanisms utilization sludge, their nutrient levels, toxic harmful substances such heavy metals, pathogenic microorganisms, antibiotics, resistant genes that affect yield, groundwater quality, ecological risks are still uncertain.

One of the main environmental stresses that hinder crop development as well yield is salt stress, while use signal molecules such calcium (Ca) has a substantial impact on reducing detrimental effects different types. Therefore, factorial pot experiment in completely randomized design was conducted to examine beneficial role Ca (0, 2.5, and 5 mM) promoting physiological, biochemical, growth traits wheat plant under three conditions viz. 0, 30, 60 mM NaCl. Foliar application increased salt-stressed plants through increasing photosynthetic pigments, IAA, proline, total soluble sugars contents improving antioxidant enzymes addition non-enzymatic antioxidants glutathione, phenol flavonoids, β-carotene, lycopene contents, thus causing decreases over-accumulation free radicals (ROS). The activity superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), which scavenge reactive oxygen species (ROS) relieved stress.

Abstract Salt-affected soils urgently need to be remediated achieve the goals of carbon neutrality and food security. Limited reviews are available on biochar performance in remediating salt-affected context climate change mitigation. This work summarized two pathways during using biochars, i.e., production from sustainable feedstock thermal technologies, application for promoting plant productivity mitigating greenhouse gas (GHG) emission. Converting biomass wastes into biochars can reduce GHG emission promote dioxide removal (CDR), collection halophyte as feedstocks, development poly-generation systems with or negativity could promising strategies. Biochar effectively improve growth soils, showing that grand mean response was 29.3%, via improving physicochemical characteristics, shifting microbial communities, enhancing halotolerance. Moreover, mitigate inducing negative priming effect, soil properties, changing communities associated nitrogen cycle, direct adsorption GHG.

Soil salinity is a serious problem facing many countries globally, especially those with semi-arid and arid climates. can have negative influences on soil microbial activity as well chemical physical processes, all of which are crucial for health, fertility, productivity. negatively affect physiological, biochemical, genetic attributes cultivated plants well. Plants wide variety responses to stress classified sensitive (e.g., carrot strawberry), moderately (grapevine), tolerant (wheat) (barley date palm) depending the salt content required cause crop production problems. Salinity mitigation represents critical global agricultural issue. This review highlights properties classification salt-affected soils, plant damage from osmotic due salinity, possible approaches (i.e., applied nutrients, inoculations, organic amendments, physio-chemical approaches, biological nano-management), research gaps that important future food security. The strong relationship between different subdisciplines (mainly, biogeochemistry, microbiology, fertility nutrition) also discussed.
