Summary: Soil salinity stress is a major obstacle to food production worldwide, with strategies such as plant breeding and genetic engineering improving plant resistance to salinity stress to meet future food demand. The use of PGPR with ACC deaminase activity has shown promise in mitigating the impact of saline conditions and improving seed germination and seedling vigor. The variation of antioxidants and osmolytes in ACC deaminase-producing PGPR treated plants is also examined.

Summary: Aerenchyma formation is crucial for oxygen diffusion in rice roots under low-oxygen conditions. Both ethylene and auxin hormones are involved in regulating aerenchyma formation in rice roots. The study found that ethylene-dependent aerenchyma formation is faster and rice roots have more aerenchyma, enabling efficient oxygen diffusion under low-oxygen conditions. Additionally, in rice, the expression levels of ethylene biosynthesis and responsive genes rapidly increase after root-cell emergence, contributing to the rapid induction of ethylene-dependent aerenchyma formation.

Summary: The objective of this study was to verify the uniform distribution of single superphosphate among seeder-fertilizer rows and its impact on crops. The experiment was conducted in Tibagi-PR, Brazil, involving crop rotation and randomized block design. The results showed no correlation between fertilizer distribution variation and significant differences in crop variables. This may be due to the alternating doses of single superphosphate and the compensation for random fertilizer variation through the years.

Summary: The physico-chemical properties of biochar, such as surface area, pH, and pyrolysis temperature, heavily influence the immobilization of PTMs. Biochar can decrease the bioavailability of PTMs in soil and plants, with specific physico-chemical attributes reducing availability by 40% and 22% respectively. Further research is needed to investigate the efficiency and potential secondary pollution of biochar in large-scale applications for PTM remediation.

Summary: The global climatic energy balance has been altered by the emission of greenhouse gases (GHGs), such as CO2, CH4, and N2O, which has led to disturbances in terrestrial ecosystems. The production of biofuels from plant biomass is seen as a promising source of renewable energy. Soil acidification is a major obstacle to crop production and a significant source of GHG emissions. Dolomite (DM) is commonly used to neutralize soil acidity and control GHG fluxes. However, the effects of DM on GHG emissions under different environmental conditions are still unclear. This meta-analysis examines the impact of DM, climate zones, and soil properties on GHG emissions, filling in the gaps in knowledge.
