“…Wheat plants subjected to water stress lessens the metabolic activity, reduces its biomass accumulation, and diminishes photosynthesis activity by curtailing chlorophyll content in leaves, leading to crop reduction [ 13 ]. Water shortage is able to prolong vegetative growth stage and decrease the leaf area, reflecting negatively on crop production [ 14 ]. Furthermore, increasing leaf temperature and reducing leaf water potential, turgor potential, and stomatal movements owing to crops’ exposure to water deficit, which eventually hinder plant growth [ 15 ].…”

Given the expectancy of the water supply becoming scarce in the future and more expensive, water conservation during wheat production processes has become very crucial especially in saline sodic soil. Biochar and salicylic acid (SA) were used to assess the potential to alleviate the influences of depletion of available soil moisture (DAM) on physicochemical, physiological, biochemical attributes, as well as wheat production absorption (Triticum aestivum L. cv. Misr 1) and macro-elements. Two seasons (2018/2019 and 2019/2020) of field trials were investigated using twelve combinations of three water treatments (50%, 70%, and 90% DAM) and foliar- and soil-applied treatments (control, biochar, salicylic acid, and biochar + SA). Biochar treated plots amplified soil physicochemical attributes, leading to improved physiological traits and antioxidant enzymes, as well as yield related traits under water limitation conditions in both years. Similarly, synergistic use of biochar and salicylic acid greatly augmented the designed characteristics such as chlorophyll a, b, K+ content, relative water content (RWC), stomatal conductance, photosynthetic rate, and intrinsic water use efficiency, whilst exhibited inhibitory effects on proline content, electrolyte leakage, Na+ content SOD, POX, CAT, and MDA, consequently increased 1000-grain weight, number of grains spike−1, grain yield, as well nutrient uptake (N, P, K) under water limitation condition in both years, followed by treatment of sole biochar or SA compared to unamended plots treatment (control). Wheat productivity achieved further increasing at 70% DAM alongside synergistic use of biochar and SA which was on par with 50% DAM under unamended plots (control). It is concluded from the findings that coupled application of biochar alongside salicylic acid accomplished an efficient approach to mitigate the injurious influences of water limitation, along with further improvement of the soil, physiology, biochemical attributes, and wheat yield, as well nutrient uptake, under saline sodic soil.

“…For instance, Lin et al (2015) noted that BC application (16 Mg ha -1 ) in saline soil increased the exchangeable K by 44%. The pH of salt-affected soils is > which decreases P availability, however, BC application can increase the availability of P in saltaffected soils because of its inherent capacity to increase P. Also, BC increases the availability of P by increasing the growth of soil bacteria (Flavobacterium, Pseudomonas and Thiobacillus) which solubilize the unavailable P present in soil (Yao et al, 2017;Ding et al, 2020). The application of BC to saline soil reduced Na uptake owing its appreciable adsorption capacity and decreasing osmotic stress, soil moisture, and nutrient concentration (Akhtar et al, 2015a).…”

Soil acidity is a serious problem in agricultural lands as it directly affects the soil, crop production, and human health. Soil acidification in agricultural lands occurs due to the release of protons (H+) from the transforming reactions of various carbon, nitrogen, and sulfur-containing compounds. The use of biochar (BC) has emerged as an excellent tool to manage soil acidity owing to its alkaline nature and its appreciable ability to improve the soil’s physical, chemical, and biological properties. The application of BC to acidic soils improves soil pH, soil organic matter (SOM), cation exchange capacity (CEC), nutrient uptake, microbial activity and diversity, and enzyme activities which mitigate the adverse impacts of acidity on plants. Further, BC application also reduce the concentration of H+ and Al3+ ions and other toxic metals which mitigate the soil acidity and supports plant growth. Similarly, soil salinity (SS) is also a serious concern across the globe and it has a direct impact on global production and food security. Due to its appreciable liming potential BC is also an important amendment to mitigate the adverse impacts of SS. The addition of BC to saline soils improves nutrient homeostasis, nutrient uptake, SOM, CEC, soil microbial activity, enzymatic activity, and water uptake and reduces the accumulation of toxic ions sodium (Na+ and chloride (Cl-). All these BC-mediated changes support plant growth by improving antioxidant activity, photosynthesis efficiency, stomata working, and decrease oxidative damage in plants. Thus, in the present review, we discussed the various mechanisms through which BC improves the soil properties and microbial and enzymatic activities to counter acidity and salinity problems. The present review will increase the existing knowledge about the role of BC to mitigate soil acidity and salinity problems. This will also provide new suggestions to readers on how this knowledge can be used to ameliorate acidic and saline soils.

Organic amendments have emerged as a pivotal component in the trajectory of sustainable agriculture, given their multifaceted contributions to soil health, crop yield, and environmental conservation. This comprehensive review delves into the intricacies of organic amendments, spanning their historical context, types, sources, nutrient profiles, and their interplay with soil and plant health. Special emphasis is laid on the integration of modern technological advancements with traditional amendment practices, exploring the synergistic potential of digital agriculture and precision farming in enhancing the efficacy of organic inputs. The review also sheds light on the economic, social, and environmental ramifications, emphasizing the role of organic amendments in smallholder versus large-scale agricultural systems and their influence on farmer resilience and consumer perceptions. Crucially, this review addresses the challenges and limitations inherent in organic amendment practices, including concerns related to quality variation, scalability, over-application, and regulatory nuances. Concomitantly, the work culminates with a forward-looking perspective, highlighting emergent trends and innovations that portend the future of organic amendments in global agriculture. The findings underscore the significance of organic amendments not merely as soil additives but as integral elements in the blueprint for a sustainable, resilient, and food-secure future.
