Soil salinization has hampered the achievement of sustainable development goals (SDGs) in many countries worldwide. Several have recently launched hyperspectral remote sensing satellites, opening new avenues for accurate soil-salinity monitoring. Among them, Gaofen-5 (GF-5) from China a high comprehensive performance, including spectral resolution 5 nm, 330 bands, and signal-to-noise ratio 700. However, potential GF-5 estimating soil salinity is not well understood. In this study, we proposed strategy that includes bootstrap methods, fractional order derivative (FOD) techniques decision-level fusion models to exploit diagnostic information reduce estimation uncertainty Ebinur Lake oasis northwestern China. The results showed data were suitable assessing salinity. FOD technique enhanced correlation between spectra, identified more improved accuracy estimation, reduced model uncertainty. low-order outperformed high-order FOD. spectra processed by 0.9 most correlated with (r = −0.76). driven 0.8 produced optimal estimated (R2 0.95, root mean square error (RMSE) 3.20 dS m−1 performance interquartile distance (RPIQ) 5.96). had less than based on original integer-order (first- second- derivatives) spectra. This study provides reference using framework low accuracy. great environmental problems facilitating further SDGs.

Climate change has devastating effects on plant growth and yield. During ontogenesis, plants are subjected to a variety of abiotic stresses, including drought salinity, affecting the crop loss (20–50%) making them vulnerable in terms survival. These stresses lead excessive production reactive oxygen species (ROS) that damage nucleic acid, proteins, lipids. Plant growth-promoting bacteria (PGPB) have remarkable capabilities combating salinity stress improving growth, which enhances productivity contributes food security. PGPB inoculation under promotes through several modes actions, such as phytohormones, 1-aminocyclopropane-1-carboxylic acid deaminase, exopolysaccharide, siderophore, hydrogen cyanide, extracellular polymeric substances, volatile organic compounds, modulate antioxidants defense machinery, abscisic thereby preventing oxidative stress. also provide osmotic balance; maintain ion homeostasis; induce salt-responsive genes, metabolic reprogramming, transcriptional changes transporter etc. Therefore, this review, we summarize mitigate its detrimental effects. Furthermore, discuss mechanistic insights towards tolerance for sustainable agriculture.

Among the environmental factors, soil salinity is one of most detrimental factors affecting plant growth and productivity. Nutritional-imbalance also known as negative effects on essential nutrients, phosphorus (P) a nutrient in which uptake, transport, distribution adversely affected by salinity-stress. Salinity-stress-mediated low P availability limits crop production. Adding additional fertilizer generally recommended to manage deficit saline-soils; however, low-efficiency available use salt-affected soils, restricts availability, fertilizers are cause significant concerns. The application salinity-tolerant phosphate–solubilizing-bacteria (ST-PSB) can be greatly effective economical way improve recover P-deficit saline-land.

Salinity stress is one of the significant abiotic stresses that influence critical metabolic processes in plant. limits plant growth and development by adversely affecting various physiological biochemical processes. Enhanced generation reactive oxygen species (ROS) induced via salinity subsequently alters macromolecules such as lipids, proteins, nucleic acids, thus constrains crop productivity. Due to which, a decreasing trend cultivable land rising world population raises question global food security. In response salt signals, plants adapt defensive mechanisms orchestrating synthesis, signaling, regulation osmolytes phytohormones. Under stress, have been investigated stabilize osmotic differences between surrounding cells cytosol. They also help protein folding facilitate functioning signaling. Phytohormones play roles eliciting adaptation plants. These responses enable acclimatize adverse soil conditions. are helpful minimizing stress-related detrimental effects on phytohormones modulate level through alteration gene expression pattern key biosynthetic enzymes antioxidative along with their role signaling molecules.

Agricultural soil degradation is occurring at unprecedented rates, not only as an indirect effect of climate change (CC) but also due to intensified agricultural practices which affect properties and biodiversity. Therefore, understanding the impacts CC on plant physiology crucial for sustainable development mitigation strategies prevent crop productivity losses. The amino acid proline has long been recognized playing distinct roles in cells undergoing osmotic stress. Due its osmoprotectant redox-buffering ability, a positive correlation between accumulation plants’ tolerance abiotic stress pointed out numerous reviews. Indeed, quantification used systematically by physiologists indicator degree measurement antioxidant potential plants under stressful conditions. Moreover, exogenous application shown increase resilience several factors, including those related such salinity exposure metals xenobiotics. However, recent data from studies often refer signal sensitivity with no clear improved activity or higher tolerance, when exogenously reliever. Nevertheless, endogenous levels are strongly modified these stresses, proving involvement responses. Hence, one main question arises—is augmentation always sign resilience? From this perspective, present review aims provide more comprehensive implications induced reinforcing idea that should be employed sole rather complemented further biochemical physiological endpoints.
