“…This natural substance has special electrochemical properties that act as a soil amender. Having alkaline nature (in most cases), a high level of cation exchange capacity, pollutant adsorption capacity, and being rich in nutrients are among the important characteristics of this organic matter ( Boateng et al., 2015 ; Batool et al., 2015 ; Javeed et al., 2022 ). Application of the biochar under different environmental stresses has improved the growth and physiological efficiency of plants.…”

IntroductionChemically modified biochars are a new generation of biochars that have a great ability to absorb and stabilize environmental pollutants. In this research, the physiological performance of mint plants (Mentha crispa L.) under fluoride and cadmium toxicities and biochar treatments was evaluated.MethodsFour levels of soil toxicities including non-toxic, 600 mg NaF kg-1 soil, 60 mg Cd kg-1 soil, and 600 mg NaF kg-1 soil + 60 mg Cd kg-1 soil were applied. The biochar addition to the soil was 25 g kg-1 (non-biochar, solid biochar, H2O2, KOH, and H3PO4-modified biochars).ResultsThe results showed that the application of biochar and especially chemically modified biochars reduced fluoride (about 15-37%) and cadmium (30-52%) contents in mint leaves, while increased soil pH and cation exchange capacity (CEC), nitrogen (12-35%), phosphorus (16-59%), potassium (17-52%), calcium (19-47%), magnesium (28-77%), iron (37-114%), zinc (45-226%), photosynthetic pigments of leaves and plant biomass (about 10-25%) under toxic conditions.DiscussionThe biochar-related treatments reduced the osmotic stress and osmolytes content (proline, soluble proteins, and carbohydrates) in plant leaves. Plant leaf water content was increased by solid and modified biochar, up to 8% in toxic conditions. Furthermore, these treatments reduced the production of stress hormones [abscisic acid (27-55%), salicylic acid (31-50%), and jasmonic acid (6-12%)], but increased indole-3-acetic acid (14-31%) in plants under fluoride and cadmium stresses. Chemically modified biochars reduced fluoride and cadmium contents of plant leaves by about 20% and 22%, respectively, compared to solid biochar.ConclusionThis result clearly shows the superiority of modified biochars in protecting plants from soil pollutants.

Water scarcity limits the amount of maize that can be produced in Ethiopia and around the world. This study was aimed to investigate the effects of amendment application and arbuscular mycorrhizal fungi (AMF) inoculation on maize growth and biomass yield in a greenhouse under both normal and water‐stressed conditions. Biochar, organic matter, and blended inorganic fertilizer (NPSB) were added as amendments. Inoculation of Gigaspora rosea and Rhizophagus clarus with the application of NPSB under normal watering has resulted in maximum heights of 96.7 and 115.0 cm, respectively. When they were subjected to water stress, their maximum heights were 65.7 and 68.01 cm. The leaf number in NPSB fertilization under regular watering was 13.3, comparable to 13.7 in R. clarus + OM and R. clarus + biochar + OM + NPSB. Under normal watering, G. rosea + NPSB and R. clarus + NPSB demonstrated the highest aboveground biomass yields of 57.7 and 47.8 g, respectively. In comparison to the control, G. rosea and R. clarus + NPSB demonstrated the highest yields of 52.9 and 42.8 g. The treatments involving G. rosea + biochar + OM + NPSB and R. clarus + biochar + OM + NPSB exhibited a greater leaf area index of 31.42 and 26.8, respectively. The treatments that were inoculated with G. rosea also showed improvements in root colonization and spore density. The study’s findings showed that both a single and a combination AMF inoculation improved every growth parameter that was looked at. To find out how well native AMF can boost maize plant yield in both normal and water‐stressed environments, more research is necessary.
